This document describes use cases that justify the extension of RDF in the current work in RDF star community group. It is collaborative work and is a non-normative part of this group output.
This document is a community working draft.
This document collects together use cases and requirments for RDF-star. These use case were provided by members of the W3C RDF Community Group on the RDF-star mailing list and issues of the community's GitHub repository.
Create a GitHub issue following the dedicated template. The suggested form is:
WHO: As an <actor> WHAT: I want a <feature> WHY: So that <benefit>
This is not mandatory.
As a materials scientist working with ontologies. I want to enrich relationships between objects. For example "A --similar--> B" with a similarity measure of 0.5, So that I can identify the pairs of objects with relationships of certain "strength". Visualization of the edges with accordingly weighted thickness would be a huge plus.
As a data service,
from an architectural perspective, interpretation should be
distinct from and cleanly layered over representation - both abstract and
concrete, in order to facilitate implementation and assure the ability to
support future use cases as knowledge evolves over time.
From this perspective, the standard treatment of blank node labels is an anti-requirement, the lessons of which should dissuade from unnecessarily restrictive relations between interpretation and representation.
The situation with blank node labels is a case where the interpretation was fixed, to treat them as referentially opaque. that was a mistake. it would have been better to separate the interpretation from the representation and to allow alternatives.
As a KG vendor, we want Stardog customers to have easy to use means to attach properties to edges in their RDF graph or load property graph data with edge properties. Here "easy" specifically means that neither the customer nor the database should have to wreck the data model (and queries) to use any of the workarounds available in plain RDF for that purpose (like the RDF reification). For example, if the customer has
:pavel :worksAt :Stardog
edge in the data and wants to add ... :since 2011 to it, neither they nor the database should have to transform it into a bunch of different triples like
[] rdf:subject :pavel ; rdf:property :worksAt ...
(and then also rewrite queries so that ?s :worksAt :Stardog still returns :pavel).
Also we want to enable customers to store that annotated statement in any named graph they want so we don't want to use named graphs for representing statement-level metadata.
As a data engineer,
I want to add meta-properties over properties, from an existing SQL-DB to a Graph-DB; that is for example
for a node of type PERSON, with a property :birthDate='1985-01-20', I want to be able to say
the property was created on '2020-11-10', by a user 'editor1' with the role 'writer'.
So that I do not need to transform the property into a relation plus yet another node.
As a member of the Wikidata community,
I would like to see triple stores
supporting the Wikidata/Wikibase data model as much as possible, so that
provenance information etc. can be represented in a way which is pleasing to the
mind and software-systems such as Wikibase.
As an UniProt developer,
I want an easier way to talk about triples we have
asserted. So that querying and parsing data-models from evidenced triples
becomes simpler.
<P26948> up:annotation <P26948#SIPDB6A831D8E2E2D2A> . <#_kb.P26948_up.annotation_A144DC8D56EA0928> rdf:type rdf:Statement ; rdf:subject <P26948> ; rdf:predicate up:annotation ; rdf:object <P26948#SIPDB6A831D8E2E2D2A> ; up:attribution <P26948#attribution-89AC1B682EEB440D50C4AEBB24FCA860> .
is a lot of bytes to type, and even worse the five joins are very expensive to perform.
Our use-case for RDFstar etc. is to allow us to talk about triples as we do now, but with a higher performance and lower barrier to entry.
We currently depend on the RDF/XML rdf:ID to easily parse this in our inhouse custom RDF parsers, and would like to keep this option open.
At the same time we deal with a lot of renaming (IRIs) for the same thing. e.g. a related database might use http://identifiers.org/uniprot/P05067 instead of http://purl.uniprot.org/uniprot/P05067. And a owl:sameAs is used to merge these datasets. Our attributions/evidences should be found no matter which IRI is used.
As an user,
I want a to be able to retrieve SPARQL results as CSV or TSV
So that I can use different toolchains to analyze the results.
As an ontologist/schema developer using SHACL
I want to specify sh:message and sh:severity for individual constraints,
e.g. attach to individual sh:minCount 1 triples because otherwise I would have
to create an individual shape (subject) just for this information.
(This use case is already implemented in TopBraid EDG product)
As a data engineer
I want to attribute nodes in relations with additional
detail so that details on the nodes is kept seperate from the property. E.g.:
two persons meet at a certain time (which is an attribute of the relation) and
one of them has a Covid-19 infection.
As an analyst I want to represent competing scenarios so that I can compare predispositions and possible outcomes. As a dispatcher in an unfolding catastrophic event I want to integrate new information into a developing model of the event so that everybody can understand the dynamics and probable developments. Both scenarios can benefit from referential transparency but also faithful reproduction of source information.
As a knowledge worker
I want to annotate statements from other named graphs and datasets where I might not even have write access
so that I can make statements about statements on the web of data like about any other entity.
I want to annotate commit deltas to an RDF graph, e.g.:
r:47e1cf2 a :Commit ; :delete <<:bob :age 23>> ; :add <<:bob :age 24>>, <<:bob :gender :male>> .
so that a triple can be searched for across commit history in SPARQL-star.
As a user, I want to express facts as triple statements `{:s :p :o}` within a triplestore. Later on I realise I want to add facts about this fact. However the {:s :p :o} triple has already been asserted in the triplestore, so I need to add a reification.
:key rdf:subject :s ; rdf:predicate :p ; rdf:object :o .
Now I can add facts about the fact:
:key :uom :cm ; :accuracy ".32" .
So far 'standard' reification.
However, as a user I want to add some RDFS 'referential' integrity to help manage the use of additional predicates such a :uom and :accuracy. Since the rdfs:domain of rdf:subject, rdf:predicate, and rdf:object, it can be inferred that :key is a rdf:Statement. This then implies that the rdfs:domain of :uom and :accuracy is also rdf:Statement. Thus if I continue reifying other statements, any predicates associated with the reified statement must have a rdfs:domain of rdf:Statement.
So as a user who wants to add some RDFS-based control over the model, I would introduce a rdfs:subClassOf so that predicates associated with this subClass have a rdfs:domain of this subclass
Triple:
:Peter :married :Beth
Reified Triple:
:marriageKey rdf:subject :Peter ; rdf:predicate :married ; rdf:object :Beth . :marriageKey a :Marriage ; :when "1980" ; :where "Kelby" .
with the following RDFS assertions:
:Marriage rdfs:subClassOf rdf:Statement .and
:when rdfs:domain :Marriage . :where rdfs:domain :Marriage .
The benefits are that I can combine triple reification with RDFS providing the same benefits that rdfs offers to rdfs:Class to rdf:Statement.
As a Big Data and & AI platform-product owner
I want the capacity to describe and query relations in the graph with the
dimension of temporal entity-events.
So that we could extract more power from the Graph, using relationships over time in stuff like job-assignment, seasonal events, and so on. In a website with a lot of annotated entities in each page and with the users navigating in that contents over time, we could also look into the user and its semantics data over time too.
So we could ask the RDF-star this kind of quotes:
As a Ph.D. student working on uncertainty,
I want to use RDF* to represent uncertainty values for RDF statements, using the mUnc ontology.
This offers the possibility to evaluate the reliability of statements in a specific
context.
See mUnc (Metadata with UNCertainty) OWL ontology for describing uncertainty information.
From EasierRDF-RDFstar/RDFStarUCandRequirements.html .
Richard Cyganiak.
I want to be able to annotate triples that are not in the graph
As an web user, I want to be able to annotate any triples, regardless of whether they are in the same graph or not. Then I can annotate triples in a graph elsewhere on the web.
Andy Seaborne
As an information engineer, I want to be able to manage annotation triples separately from the data triples themselves. I wish to have a separategraph in the same RDF dataset. This will make data management more convenient - e.g. publishing without annotations; e.g. querying the data without the annotations visible.
Dan Brickley
I want to use an RDF-star triple to capture something like, e.g., "the graph denoted by IRI ex:mygraph contains the edge/triple (ex:Bob, foaf:knows, ex:Alice)."
Ghislain Atemezing
I want to combine TriG notation / Named Graph / RDF-star all together. What is feasible or not with RDF-star?

In Her Own Write is a Scorpio ENFP 4w3. All grammar mistakes made on this website is excused because she is not good at grammar. Dear viewers are highly recommended to read the Origin Story here.
Bored in quarantine, I suddenly had the urge to make a blog and talk about 'stuff'. With the help of my little coding superpowers, In Her Own Write was founded on April 3 2020, but the website was officially published on April 5.
The main reason for me starting this is to show some other sides of me. Basically, I don't want one part of me to define me. We all want to show parts of ourselves we want to show other people, but not the insecurities and worries. Here, I will try to comfortably open up and talk about stuff. Not like super personal stuff though, just other parts of my brain that deserves everyone's attention. I hope this won't be awkward cuz really, this is my place to talk and I get to do my own show.
I've always imagined myself as a stand-up comedian, talking about my anecdotes and unnecessary opinions (that no one asked). My time to shine. Hope I won't get cancelled for this.

Bradlee Speice, Sat 05 March 2016, Blog
It's time! After embarking on a Machine Learning class this semester, and with a Saturday in which I don't have much planned, I wanted to put this class and training to work. It's my first competition submission. I want to walk you guys through how I'm approaching this problem, because I thought it would be really neat. The competition is Banco Santander's Santander Customer Satisfaction competition. It seemed like an easy enough problem I could actually make decent progress on it.
First up: we need to load our data and do some exploratory work. Because we're going to be using this data for model selection prior to testing, we need to make a further split. I've already gone ahead and done this work, please see the code in the appendix below.
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
%matplotlib inline
# Record how long it takes to run the notebook - I'm curious.
from datetime import datetime
start = datetime.now()
dataset = pd.read_csv('split_train.csv')
dataset.index = dataset.ID
X = dataset.drop(['TARGET', 'ID', 'ID.1'], 1)
y = dataset.TARGET
y.unique()
len(X.columns)
Okay, so there are only two classes we're predicting: 1 for unsatisfied customers, 0 for satisfied customers. I would have preferred this to be something more like a regression, or predicting multiple classes: maybe the customer isn't the most happy, but is nowhere near closing their accounts. For now though, that's just the data we're working with.
Now, I'd like to make a scatter matrix of everything going on. Unfortunately as noted above, we have 369 different features. There's no way I can graphically make sense of that much data to start with.
We're also not told what the data actually represents: Are these survey results? Average time between contact with a customer care person? Frequency of contacting a customer care person? The idea is that I need to reduce the number of dimensions we're predicting across.
My first attempt to reduce the data dimensionality is to find all the binary classifiers in the dataset (i.e. 0 or 1 values) and see if any of those are good (or anti-good) predictors of the final data.
cols = X.columns
b_class = []
for c in cols:
if len(X[c].unique()) == 2:
b_class.append(c)
len(b_class)
So there are 111 features in the dataset that are a binary label. Let's see if any of them are good at predicting the users satisfaction!
# First we need to `binarize` the data to 0-1; some of the labels are {0, 1},
# some are {0, 3}, etc.
from sklearn.preprocessing import binarize
X_bin = binarize(X[b_class])
accuracy = [np.mean(X_bin[:,i] == y) for i in range(0, len(b_class))]
acc_df = pd.DataFrame({"Accuracy": accuracy}, index=b_class)
acc_df.describe()
Wow! Looks like we've got some incredibly predictive features! So much so that we should be a bit concerned. My initial guess for what's happening is that we have a sparsity issue: so many of the values are 0, and these likely happen to line up with satisfied customers.
So the question we must now answer, which I likely should have asked long before now: What exactly is the distribution of un/satisfied customers?
unsat = y[y == 1].count()
print("Satisfied customers: {}; Unsatisfied customers: {}".format(len(y) - unsat, unsat))
naive_guess = np.mean(y == np.zeros(len(y)))
print("Naive guess accuracy: {}".format(naive_guess))
This is a bit discouraging. A naive guess of "always satisfied" performs as well as our best individual binary classifier. What this tells me then, is that these data columns aren't incredibly helpful in prediction. I'd be interested in a polynomial expansion of this data-set, but for now, that's more computation than I want to take on.
Knowing that our naive guess performs so well is a blessing and a curse:
Now, in removing these features from the dataset, I'm not saying that there is no "information" contained within them. There might be. But the only way we'd know is through a polynomial expansion, and I'm not going to take that on within this post.
My initial thought for a "next guess" is to use the LDA model for dimensionality reduction. However, it can only reduce dimensions to $1 - p$, with $p$ being the number of classes. Since this is a binary classification, every LDA model that I try will have dimensionality one; when I actually try this, the predictor ends up being slightly less accurate than the naive guess.
Instead, let's take a different approach to dimensionality reduction: principle components analysis. This allows us to perform the dimensionality reduction without worrying about the number of classes. Then, we'll use a Gaussian Naive Bayes model to actually do the prediction. This model is chosen simply because it doesn't take a long time to fit and compute; because PCA will take so long, I just want a prediction at the end of this. We can worry about using a more sophisticated LDA/QDA/SVM model later.
Now into the actual process: We're going to test out PCA dimensionality reduction from 1 - 20 dimensions, and then predict using a Gaussian Naive Bayes model. The 20 dimensions upper limit was selected because the accuracy never improves after you get beyond that (I found out by running it myself). Hopefully, we'll find that we can create a model better than the naive guess.
from sklearn.naive_bayes import GaussianNB
from sklearn.decomposition import PCA
X_no_bin = X.drop(b_class, 1)
def evaluate_gnb(dims):
pca = PCA(n_components=dims)
X_xform = pca.fit_transform(X_no_bin)
gnb = GaussianNB()
gnb.fit(X_xform, y)
return gnb.score(X_xform, y)
dim_range = np.arange(1, 21)
plt.plot(dim_range, [evaluate_gnb(dim) for dim in dim_range], label="Gaussian NB Accuracy")
plt.axhline(naive_guess, label="Naive Guess", c='k')
plt.axhline(1 - naive_guess, label="Inverse Naive Guess", c='k')
plt.gcf().set_size_inches(12, 6)
plt.legend();
**sigh...** After all the effort and computational power, we're still at square one: we have yet to beat out the naive guess threshold. With PCA in play we end up performing terribly, but not terribly enough that we can guess against ourselves.
Let's try one last-ditch attempt using the entire data set:
def evaluate_gnb_full(dims):
pca = PCA(n_components=dims)
X_xform = pca.fit_transform(X)
gnb = GaussianNB()
gnb.fit(X_xform, y)
return gnb.score(X_xform, y)
dim_range = np.arange(1, 21)
plt.plot(dim_range, [evaluate_gnb(dim) for dim in dim_range], label="Gaussian NB Accuracy")
plt.axhline(naive_guess, label="Naive Guess", c='k')
plt.axhline(1 - naive_guess, label="Inverse Naive Guess", c='k')
plt.gcf().set_size_inches(12, 6)
plt.legend();
Nothing. It is interesting to note that the graphs are almost exactly the same: This would imply again that the variables we removed earlier (all the binary classifiers) indeed have almost no predictive power. It seems this problem is high-dimensional, but with almost no data that can actually inform our decisions.
After spending a couple hours with this dataset, there seems to be a fundamental issue in play: We have very high-dimensional data, and it has no bearing on our ability to actually predict customer satisfaction. This can be a huge issue: it implies that no matter what model we use, we fundamentally can't perform well. I'm sure most of this is because I'm not an experienced data scientist. Even so, we have yet to develop a strategy that can actually beat out the village idiot; so far, the bank is best off just assuming all its customers are satisfied. Hopefully more to come soon.
end = datetime.now()
print("Running time: {}".format(end - start))
Code used to split the initial training data:
from sklearn.cross_validation import train_test_split
data = pd.read_csv('train.csv')
data.index = data.ID
data_train, data_validate = train_test_split(
data, train_size=.7)
data_train.to_csv('split_train.csv')
data_validate.to_csv('split_validate.csv')

--- title: Drug use was falling, but that seems to be changing author: Matt Ashby date: '2019-04-30' slug: drug-use draft: true categories: [] tags: - crime - CSEW - drugs ---
Self-reported drug use has fallen for most of the past 20 years, but in the past six years the use of cannabis, cocaine and ecstasy has increased, particularly among people aged 16–24. However, drug use is still lower now than it was at the turn of the millenium.

The Heisenberg Equation (Part 1)
Introduction
Most students of quantum mechanics are familiar with the Schrodinger equation:
\[\begin{equation} i\hbar \frac{d \psi (t)}{dt} = H \psi (t) \end{equation}\]It is the starting point for a huge number of derivations and solutions in the quantum world. Arguably, it is the most important equation in non-relativistic quantum mechanics. However, the Schrodinger equation has an often neglected twin brother - the Heisenberg equation. If we simply shift our focus from wavefunctions to operators, we find that the quantum world is much deeper than we once thought.
Let’s start off with the simple example of the time evolution of expectation values. We will use that as a stepping stone to derive the Heisenberg equation.
The Time Evolution of an Expectation Value
Suppose I have some operator \(Q\) with an expectation value given by:
\[\begin{equation} \left \langle Q \right \rangle = \left \langle \psi (t) \right | Q \left | \psi (t) \right \rangle \equiv \left \langle \psi \right | Q \left | \psi \right \rangle \end{equation}\]I want to calculate how \(\left \langle Q \right \rangle\) evolves as a function of time. To start off I can take a time derivative of the expression above and expand it using the product rule.
\[\begin{align} \frac{d}{dt} \left \langle Q \right \rangle &= \frac{d}{dt} \left [ \left \langle \psi \right | Q \left | \psi \right \rangle \right ]\\[0.1cm] &= \left \langle \frac{d \psi}{dt} \bigg | \hspace{0.5mm} Q \hspace{0.5mm} \bigg | \psi \right \rangle + \left \langle \psi \bigg | \frac{dQ}{dt} \bigg | \psi \right \rangle + \left \langle \psi \bigg | \hspace{0.5mm} Q \hspace{0.5mm} \bigg | \frac{d \psi}{dt} \right \rangle \end{align}\]The Schrodinger equation tells us how the time derivative of the wavefunction is related to the Hamiltonian of the system. Thus, we can substitute the expression for the Hamiltonian in for the time derivatives. Remember, we do have to take into account the fact that the bra and ket terms differ by a minus sign:
\[\begin{equation} \left | \frac{d\psi}{dt} \right \rangle = \left | \frac{1}{i\hbar} H \psi \right \rangle \end{equation}\] \[\begin{equation} \left \langle \frac{d\psi}{dt} \right | = \left \langle -\frac{1}{i\hbar} H \psi \right | \end{equation}\]Then:
\[\begin{align} \frac{d}{dt} \left \langle Q \right \rangle &= \left \langle \frac{d \psi}{dt} \bigg | \hspace{0.5mm} Q \hspace{0.5mm} \bigg | \psi \right \rangle + \left \langle \psi \bigg | \frac{dQ}{dt} \bigg | \psi \right \rangle + \left \langle \psi \bigg | \hspace{0.5mm} Q \hspace{0.5mm} \bigg | \frac{d \psi}{dt} \right \rangle\\[0.1cm] &= \left \langle \left ( -\frac{1}{i\hbar}H\psi \right ) \bigg | \hspace{0.5mm} Q \hspace{0.5mm} \bigg | \psi \right \rangle + \left \langle \psi \bigg | \frac{dQ}{dt} \bigg | \psi \right \rangle + \left \langle \psi \bigg | \hspace{0.5mm} Q \hspace{0.5mm} \bigg | \left ( \frac{1}{i\hbar}H\psi \right ) \right \rangle\\[0.1cm] &= \left \langle \left ( -\frac{1}{i\hbar}H\psi \right ) \bigg | \hspace{0.5mm} Q \hspace{0.5mm} \bigg | \psi \right \rangle + \left \langle \psi \bigg | \hspace{0.5mm} Q \hspace{0.5mm} \bigg | \left ( \frac{1}{i\hbar}H\psi \right ) \right \rangle + \left \langle \psi \bigg | \frac{dQ}{dt} \bigg | \psi \right \rangle \end{align}\]Factoring out the \(-(i\hbar)^{-1}\) term yields:
\[\begin{align} \frac{d}{dt} \left \langle Q \right \rangle &= -\frac{1}{i\hbar} \left [ \left \langle H \psi \right | Q \left | \psi \right \rangle - \left \langle \psi \right | Q \left | H \psi \right \rangle \right ] + \left \langle \psi \bigg | \frac{dQ}{dt} \bigg | \psi \right \rangle\\[0.1cm] &= -\frac{1}{i\hbar} \left [ \left \langle \psi \right | HQ \left | \psi \right \rangle - \left \langle \psi \right | QH \left | \psi \right \rangle \right ] + \left \langle \psi \bigg | \frac{dQ}{dt} \bigg | \psi \right \rangle\\[0.1cm] &= -\frac{1}{i\hbar} \left \langle \psi \right | HQ - QH \left | \psi \right \rangle + \left \langle \psi \bigg | \frac{dQ}{dt} \bigg | \psi \right \rangle\\[0.1cm] &= -\frac{1}{i\hbar} \left \langle \psi \right | [H,Q] \left | \psi \right \rangle + \left \langle \psi \bigg | \frac{dQ}{dt} \bigg | \psi \right \rangle\\[0.1cm] \end{align}\]Now we can write out the final expression for the time evolution of the expectation value:
\[\begin{equation} \frac{d\left \langle Q \right \rangle}{dt} = \frac{i}{\hbar} \left \langle [H,Q] \right \rangle + \left \langle \frac{dQ}{dt} \right \rangle \end{equation}\]This is a neat result! It gives a simple expression for the time evolution of the expectation value of \(Q\).
The Heisenberg Equation
Let’s take a step back and approach quantum mechanics in a slightly different way. In the last section we assumed that the operators were constant in time and the wavefunction had some time dependence. Now, we will assume that the wavefunction is constant in time and move the time dependence to the operators.
The wavefunction of a particle at some final time \(t\) is equal to the wavefunction of the particle at some initial time \(t_o\) multiplied by a unitary operator.
\[\begin{equation} \psi (t) = U(t,t_o) \psi (t_o) \end{equation}\]In the expression above, \(\psi(t_o)\) is a constant wavefunction and the unitary operator \(U\) carries all of the time dependence of the system. We can substitute the expression for \(\psi(t)\) into the Schrodinger equation and solve for \(U\):
\[\begin{equation} i\hbar \frac{d\psi(t)}{dt} = H \psi(t) \end{equation}\] \[\begin{equation} i\hbar \frac{d}{dt} \left [ U(t,t_o) \psi (t_o) \right ] = H U(t,t_o) \psi (t_o) \end{equation}\]The unitary operator \(U\) is a function of time \(t\). However, the wavefunction \(\psi(t_o)\) is not a function of \(t\). Thus, we can pull \(\psi(t_o)\) out of the time derivative.
\[\begin{equation} i\hbar \frac{dU(t,t_o)}{dt} \psi (t_o) = H U(t,t_o) \psi (t_o) \end{equation}\]This expression needs to be true for any initial condition \(\psi(t_o)\). Thus, we will cancel \(\psi(t_o)\) on each side of the expression.
\[\begin{equation} i\hbar \frac{dU(t,t_o)}{dt} = H U(t,t_o) \end{equation}\]Just to simplify our notation, we will let \(U(t,t_o) \equiv U\).
\[\begin{equation} i\hbar \frac{dU}{dt} = HU \end{equation}\]That is pretty neat. The expression for \(U\) above is almost identical to the expression for \(\psi(t)\) in the previous section. Let’s solve for the expectation value of some operator \(Q\) like we did in the previous section. Starting with the definition of an expectation value, we get:
\[\begin{align} \left \langle Q \right \rangle &= \left \langle \psi (t) \right | Q \left | \psi (t) \right \rangle\\[0.1cm] &= \left \langle \psi (t_o) U^\dagger \right | Q \left | U \psi (t_o) \right \rangle\\[0.1cm] &= \left \langle \psi (t_o) \right | U^\dagger Q U \left | \psi (t_o) \right \rangle\\[0.1cm] \end{align}\]We can rewrite the time-dependent operator in terms of the time-independent operator and a unitary operator. To keep our notation clear, I will call \(Q_H\) the time-dependent operator and \(Q_S \equiv Q\) the time-independent operator.
No, they aren’t :)
The final expression in the first section gives the time derivative of the expectation value of an operator. The final expression in the second section gives the time derivative of an operator in the Heisenberg picture (i.e. the model of quantum mechanics where the wavefunctions are constant and the operators evolve in time). They describe two different things under two different models of quantum mechanics. However, the final expressions are almost identical in form, alluding to the fact that these two models of quantum mechanics are intimately related.
What we should take away from this is that the Schrodinger equation is not the end-all equation of quantum mechanics. Sometimes, the Heisenberg equation can yield very useful insights into the properties of a system. Additionally, any calculations done using the Schrodinger equation are intimately related to the calculations done using the Heisenberg equation due to the similarity of the expressions calculated above.
Next week, we will solve some specific examples using the Heisenberg equation and see how the solutions relate to those of the Schrodinger equation.

For Bezier controller keys, the following properties are accessible:
Properties
<key>.time Time -- time value or number (interpreted as frames)
<key>.selected Boolean -- specifies whether the key is selected
<key>.value varies -- class determined by its containing controller
<key>.inTangent varies -- float or point3 (see below)
<key>.outTangent varies -- float or point3 (see below)
<key>.inTangentType Name -- see list of permitted names below
<key>.outTangentType Name -- see list of permitted names below
<key>.inTangentLength Float
<key>.outTangentLength Float
<key>.freeHandle Boolean
<key>.x_locked Boolean default: true
<key>.y_locked Boolean default: true
<key>.z_locked Boolean default: true
<key>.constantVelocity Boolean default: false
The .inTangent and .outTangent values are Floats in keys of float controllers and Point3s for the other appropriate controllers. Default value is 0 for float controllers, [0,0,0] otherwise.
The .inTangentType and .outTangentType properties have symbolic name values representing the 6 possible tangent types available in the drop-down menu in the Bezier key property dialog:
#smooth (default)
#linear
#step
#fast
#slow
#custom
#auto
.inTangentLength and .outTangentLength, (typically a fraction from 0 to 1) represent how long the handle is towards the adjacent key. For example, a value of 0.5 means the handle reaches halfway from the current key to the adjacent key, and a value of 1 reaches all the way. If the handle reaches beyond the adjacent key, it will be greater than one. If there is no previous key, the value of .inTangentLength will be -1.
There is a check box to the key property/Master Point control dialog found in the Motion Panel. It is called Free Handle. When Free Handle is checked, the user can move the horizontal handle where ever s/he feels. Otherwise, s/he is constrained, to prevent discontinuities.
Correspondingly, there is a bezier key property called .freeHandle that implements the functionality described above.
Examples:
c = bezier_position () -- create and assign new controller
$bar.pos.controller = c
k = addNewKey c 0f -- add a key at frame 0
k.value = [10,0,0] -- set value there
k.outTangentType = #slow -- and outgoing tangent type
k = addNewKey c 100f -- add another key at 100
k.value = [200,10,0] -- set value
k.inTangentType = #custom -- make inTangent custom
k.inTangent = [0.2, 0.02, 0.112] -- set its tangents
k.x_locked = false -- and unlock handles
Note: There are a fair number of classes that don't implement the showproperties method. MAXKey is one of them. getPropNames is not implemented for it either.

HTML structure
Each HTML page contains a header, content blocks and a footer. In some pages a title block is added right before the content block. The home page content is made up of independent content blocks rather than 1 single content block. The diagrams below shows the hierachy and arrangement of the different sections. Note that the 1st section(page wrapper) wraps all the other sections.
It is easier to modify the existing page templates rather than creating new ones. However, if you must, make sure you use the exact id names and class names used in the other pages.
CSS Structure
All style sheets used with exception to bootstrap and the included fonts are located in the css folder.
- The main css is file named default.css
- default.css must be referenced on every page
The popular css pre-processor Sass was used to generate the main stylesheet. You can still edit the file directly but it may be better to work with the source Sass files instead.
Sass Structure
All Sass files can be found in the sass folder. When compiled, any css output files are copied to the css directory.
- Different sections have been organized inside directories and sub directories.
- The main sass files is named default.scss and imports all the required sections
- When default.scss is compiled it gereates default.css which is copied to the css directory
If you do not need any of the sections you can simply delete the section's import statement in default.scss
Which is the main CSS/SASS file?
The main Sass file is named default.scss and generates default.css when compiled.
Working with SASS
Sass is an extension of CSS that adds power and elegance to the basic language.  Sass helps keep large stylesheets well-organized, and get small stylesheets up and running quickly

For an in depth explanation of SASS and information on usage please visit http://sass-lang.com/
Free SASS compilers
There are many GUI SASS compilers that be downloaded online.
- CodeKit (Paid)
- Compass.app (Paid, Open Source)
- Hammer
- Koala (Open Source)
- LiveReload
- Mixture (Paid)
- Prepros (Open Source)
- Prepros Pro (Paid)
- Scout (Open Source)
The free application Koala was used to compile the SASS files in this theme
Using Koala compile SASS files
The first time you run Koala a screen similar to the one below should open.
The next thing you should do is load the included Sass files. You do this by locating the entire sass directory in windows explorer and dragging it to the app as indicated. Once you do this Koala will try to list all the Sass files it can find in the directory.
Only select default.scss since it references all the other SASS files. Make sure to de-select the compass mode option on the right then click compile. Thats it ! default.scss should be compiled to default.css and copied to the css folder.
compiling changes
Whenever you edit any of the the stylesheets, always run Koala and compile the changes.
Sass files should be treated just like regular css files. Use the same properties, values and syntax that you would use with a css stylesheet.
Auto compiling changes
If you do not want to click compile everytime you make changes, simply select the auto-compile option on the right. Now Koala will watch all the files in the sass directory and automatically compile any changes.
Remember to compile any new changes!
The main stylesheets default.scss needs to be compiled every time you make changes. You can select the Auto Compile option in Koala to automate this process.
Compressing Stylesheets
If you want compress the generated files, simply select the desired compression level found in the options. Koala will remember the setting even if you have selected a file to be auto compiled.
Changing SASS Variables
If you examine the main Sass files you will find that many variables have been used to setup the layout and skin of the theme.
- All the variables are contained in file named _variables.scss
- Boolean variables should be entered as either true or false
- Integer variables should be entered in the same units as the previous value
Changing Skin Color
Only 2 colors are used to generate a new skin. The variables in the SASS files are named as follows:
- $color-1 - The bright color
- $color-2 - The dark color
All the available skin files can be found in the "css / skins" directory. To create your own simply copy and rename any of the available skins and replace the color values with your own.
Once you have saved the new skin, simply import it in the default.scss file as shown below. Compile the file and new colors will be reflected throughout the theme.
Changing Twitter and Flickr Feeds
Changing the feeds is easy. Navigate to the js folder and open template.js and find the sections shown below
Simply replace the account names highlighted with your own.
Portfolio
Replacing the portfolio with your own items is easy. Before you start take note of the following:
- All preview images must have the same dimensions so that they align with the grid.
- The full size images that preview images link to can be of any dimensions.
- You must use the same filter words you put in the filter menu as the ones you input in the data-type attribute in the portfolio list.
Once you collect and group your items/images, you should replace the the values in the filter menu with your own category names. The class attribute holds the category name which must be one word as this value links to items with the same data-type in the portfolio.
Responsive Carousels
The popular open source responsive slider plugin BxSlider has been modified to accept breakpoints for different screen sizes. The modifications allow you to set the number of slides to be shown on different screen sizes using a simple data attribute. There is no limit on the range of screen sizes you can target!
1. setup your slider
First setup your carousel as you would setup any other bx slider slider.

2. set default options
You can use a handy data attribute I created called data-options to pass any configuration options. All of BxSlider's options are supported together with 5 new additional options.
- screen: defines a minimum screen size to target
- slides: a quick way of setting both min and max slides with one value
- autoReload: forces the slider to be reloaded when the screen size changes
- parentSelector: reference to a parent element if it exists
- removeParentClass: removes a named class from the parent once the slider loads. Useful when you want to disable some styles once the slider loads.

3. Define break points
Each break point is defined as a set configuration objects enclosed in curly brackets. All of BxSlider's options are supported.
[{screen:460, slides:2, pager:false, controls:true}]
The above will be interpreted as follows:
- Target a minimum screen size of 460px
- Only show 2 slides at that screen size
- Set the pager option to false at that screen size
- Set the controls option to true at that screen size
Multiple break points are separated by commas and set inside a data attribute named data-breaks. To target the least possible screen size use screen:0
data-breaks="[{screen:0, slides:1, pager:false},{screen:460, slides:2},{screen:768, slides:3}]"
4. Put everything together
This is how your slider should look once you put everything together.

Now just call the bxSlider function the usual way.
$(document).ready( function() {
$('#myslider').bxSlider();
});
If you prefer not to use data attributes, the breaks and other new options can still be passed during the call.
$(document).ready( function() {
$('#myslider').bxSlider({
slideMargin: 5,
autoReload: true,
breaks: [{screen:0, slides:1, pager:false},{screen:460, slides:2},{screen:768, slides:3}]
});
});
Calling the slider without any code!
If you do not want to manually call each an every slider you setup, you can use a new attribute called data-call and the slider will call itself!

tool - TclOO Library (TOOL) Framework
This module implements the Tcl Object Oriented Library framework, or TOOL. It is intended to be a general purpose framework that is useable in its own right, and easily extensible.
TOOL defines a metaclass with provides several additional keywords to the TclOO description langauge, default behaviors for its consituent objects, and top-down integration with the capabilities provided by the oo::meta package.
The TOOL metaclass was build with the oo::dialect package, and thus can be used as the basis for additional metaclasses. As a metaclass, TOOL has it's own "class" class, "object" class, and define namespace.
package require tool # tool::class workds just like oo::class tool::class create myclass { } # tool::define works just like oo::define tool::define myclass method noop {} {} # tool::define and tool::class understand additional keywords tool::define myclass array_ensemble mysettings mysettings {} # And tool interoperates with oo::define oo::define myclass method do_something {} { return something } # TOOL and TclOO objects are interchangeable oo::class create myooclass { superclass myclass }
Several manual pages go into more detail about specific keywords and methods.
TOOL adds new (or modifies) keywords used in the definitions of classes. However, the new keywords are only available via calls to tool::class create or tool::define
Defines a method for the class object itself. This method will be passed on to descendents of the class, unlike self method.
Declares a variable name which will be initialized as an array, populated with contents for objects of this class, as well as any objects for classes which are descendents of this class.
Declares a method ensemble methodname which will control access to variable varname. Cases are a key/value list of method names and bodies which will be overlaid on top of the standard template. See tool::array_ensemble.
One method name is reserved: initialize. initialize Declares the initial values to be populated in the array, as a key/value list, and will not be expressed as a method for the ensemble.
Declares a method ensemble methodname which will control access to variable varname. Cases are a key/value list of method names and bodies which will be overlaid on top of the standard template. See tool::dict_ensemble.
One method name is reserved: initialize. initialize Declares the initial values to be populated in the array, as a key/value list, and will not be expressed as a method for the ensemble.
If methodname contains ::, the method is considered to be part of a method ensemble. See tool::method_ensembles. Otherwise this command behaves exactly like the standard oo::define method command.
Declares an option. dictopts is a key/value list defining parameters for the option. See tool::option_handling.
tool::class create myclass { option color { post-command: {puts [list %self%'s %field% is now %value%]} default: green } } myclass create foo foo configure color purple > foo's color is now purple
Defines a new leaf in the class metadata tree. With no branch, the leaf will appear in the const section, accessible by either the object's property method, or via oo::meta::info class get const field:
Declares a variable name which will be initialized with the value value for objects of this class, as well as any objects for classes which are descendents of this class.
The TOOL object mother of all classes defines several methods to enforces consistent behavior throughout the framework.
Return the value of this object's option option. If the property options_strict is true for this class, calling an option which was not declared by the option keyword will throw an error. In all other cases if the value is present in the object's options array that value is returned. If it does not exist, the object will attempt to retrieve a property of the same name.
This command will inject new values into the objects options array, according to the rules as set forth by the option descriptions. See tool::option_handling for details. configure will strip leading -'s off of field names, allowing it to behave in a quasi-backward compatible manner to tk options.
This command will inject new values into the objects options array, according to the rules as set forth by the option descriptions. This command will perform validation and alternate storage rules. It will not invoke trigger rules. See tool::option_handling for details.
A passthrough to oo:objdefine [self] forward
Delegates the <stub> method to the object or command designated by forward
tool::object create A tool::object create B A graft buddy B A configure color red B configure color blue A cget color > red A <buddy> cget color > blue
Consults the metadata for the class to ensure every array, option, and variable which has been declared but not initialized is initialized with the default value. This method is called by the constructor and the morph method. It is safe to invoke multiple times.
Executes a block of text within the namespace of the object. Lines that begin with a # are ignored as comments. Commands that begin with :: are interpreted as calling a global command. All other Tcl commands that lack a "my" prefix are given one, to allow the script to exercise internal methods. This method is intended for configuration scripts, where the object's methods are intepreting a domain specific language.
tool::class myclass { constructor script { my Eval_Script $script } method node {nodename info} { my variable node dict set node $nodename $info } method get {args} { my variable node return [dict get $node $args] } } myclass create movies { # This block of code is executed by the object node {The Day the Earth Stood Still} { date: 1952 characters: {GORT Klatoo} } } movies get {The Day the Earth Stood Still} date: > 1952
Computes the default value for an option. See tool::option_handling.
