characteristics
This document describes the requirements for the XQuery Update Facility. [XQuery 1.0] provides queries, but has no support for adding new values or changing existing values. The XML Query Working Group intends to add support for updates in a future version of XQuery.
The following usage scenarios describe how the XQuery Update Facility may be used in various environments, and represent a wide range of activities and needs that illustrate the problem space to be addressed. They are intended to be used as design cases during the development of the XQuery Update Facility, and should be reviewed when critical decisions are made. These usage scenarios should also prove useful in helping non-members of the XML Query Working Group understand the intent and goals of the project.
Modify XML in persistent XML stores, including native XML databases, XML files stored on a file system, or XML stored in SQL databases.
Modify XML messages to change status and add information created while processing the message.
Add new data to an existing XML document; for instance, add a new entry to a BLOG or a data log.
Perform updates on configuration files, user profiles, or administrative logs represented in XML.
Create a new copy of an XML document or subtree that differs from the original in the way specified by the update. For instance, updates could be used to modify a web message in order to add new information and change headers to reflect the modified status.
Modifying XML views of non-XML sources, such as a [SQL/XML] view of a SQL database.
The following key words are used throughout the document to specify the extent to which an item is a requirement for the work of the XML Query Working Group:
This word means that the item is an absolute requirement.
This word means that there may exist valid reasons not to treat this item as a requirement, but the full implications should be understood and the case carefully weighed before discarding this item.
This word means that an item deserves attention, but further study is needed to determine whether the item should be treated as a requirement.
When the words MUST, SHOULD, or MAY are used in this technical sense, they occur as a hyperlink to these definitions. These words will also be used with their conventional English meaning, in which case there is no hyperlink. For instance, the phrase "the full implications should be understood" uses the word "should" in its conventional English sense, and therefore occurs without the hyperlink.
The syntax for updates MAY have more than one syntax binding. One syntax MUST be convenient for humans to read and write.
Status: this requirement has been met.
One syntax MUST be expressed in XML in a way that reflects the underlying structure of the operations.
Status: this requirement has been met.
The XQuery Update Facility MUST be declarative. Notably, it MUST be independent of any particular evaluation strategy.
Status: this requirement has been met.
The XQuery Update Facility MUST be defined independently of any protocols with which it is used.
Status: this requirement has been met.
The XQuery Update Facility MUST define standard error conditions that can occur during the execution of an update.
Status: this requirement has been met.
The XQuery Update Facility SHOULD provide an optional static type checking feature.
Status: this requirement has been met.
The XQuery Update Facility MUST be defined on the [XQuery 1.0 and XPath 2.0 Data Model].
Status: this requirement has been met.
Note:
The properties of a Data Model instance that can be modified by the XQuery Update Facility are discussed in 3.4 XML Query Update Functionality.
The XQuery Update Facility MUST be based on [XQuery 1.0]. The XQuery Update Facility MUST use XQuery to identify items to be updated. The XQuery Update Facility MUST use XQuery to specify items used in the updates.
Status: this requirement has been met.
The XQuery Update Facility MUST be able to change the properties of existing nodes while preserving their identity. The XQuery Update Facility MUST be able to create a new copy of a node with a specific set of changes.
Status: this requirement has been met.
The XQuery Update Facility MUST be able to delete nodes.
Status: this requirement has been met.
The XQuery Update Facility MUST be able to insert new nodes in specified positions.
Status: this requirement has been met.
The XQuery Update Facility MUST be able to replace a node.
Status: this requirement has been met.
The XQuery Update Facility MUST be able to change the value returned by the typed-value accessor for a node.
Status: this requirement has been met.
The XQuery Update Facility SHOULD be able to modify some of the properties of a node such as the name, type, content, nilled, base-URI, etc.
Status: this requirement has been met. The base-URI can not be modified.
The XQuery Update Facility MAY be able to move a node from one location to another.
Status: this requirement has not been met. A node can be deleted, and a copy inserted in a new location, but it will have a new identity. The Working Group felt that this functionality would limit the environments in which the XQuery Update Facility could be implemented.
The XQuery Update Facility MUST be able to do conditional updates.
Status: this requirement has been met.
The XQuery Update Facility MUST be able to iterate over nodes to do updates.
Status: this requirement has been met.
The XQuery Update Facility MAY support an explicit XML Schema validation operation that preserves node identity.
This requirement has not been met according to its original formulation; however, the revalidation mode can be set to ensure that type information is recovered and the resulting document is valid according to the governing schema.
Note:
The XQuery 1.0 validate expression creates a new copy of each validated node, with a new identity. This requirement involves preservation of identity.
The XQuery Update Facility MUST be able to compose update operators with other update operators.
Status: this requirement has been met.
The XQuery Update Facility MAY be compositional with respect to XQuery expressions; that is, it may be possible to use an update wherever an XQuery expression is used.
Status: this requirement has not been met Updating expressions are limited to specific syntactic contexts..
The XQuery Update Facility SHOULD provide a means to parameterize update operations.
Status: this requirement has been met. Updating functions and external variables may both be used to parameterize update operations.
In this section, the terms Atomicity, Consistency, Isolation, and Durability are taken from the ACID model of transaction characteristics for databases, which is described in [Transaction Processing Concepts and Techniques].
The XQuery Update Facility MUST provide a set of atomic operations, and MUST define a means to group atomic operations into an atomic execution unit.
Status: this requirement has been met. Multiple atomic operations can be done in a single query, which constitutes the atomic execution unit.
At the end of an outermost update operation (that is, an update operation invoked from the external environment), the data model MUST be consistent with respect to the constraints specified in the Data Model. In particular, all type annotations MUST be consistent with the content of the items they govern.
Status: this requirement has been met.
The XQuery Update Facility MAY define additional levels of granularity at which Data Model constraints are enforced.
Status: this requirement has not been met.
The XQuery Update Facility SHOULD define the means by which operations can be isolated from concurrent operations.
The XQuery Update Facility defines operations purely in terms of the XML Data Model. Propagation of XDM changes to an underlying persistent store or other software system is beyond the scope of this specification. This includes isolation.
The XQuery Update Facility MUST define a means to control the durability of atomic operations and atomic execution units.
The XQuery Update Facility defines operations purely in terms of the XML Data Model. Propagation of XDM changes to an underlying persistent store or other software system is beyond the scope of this specification. This includes durability.


--- layout: page title: External Interfaces bigimg: /images/external-interfaces.jpg ---
Apps like the ones mentioned above allow to execute actions based on external events. Those events may well be the connection to a WLAN, the entering of some area. Those events are pretty useful if combined with an FHEM instance. This is why andFHEM provides an external interface to those apps.
AndFHEM provides a UI for sending commands to FHEM. Just look for an andFHEM plugin in your favourite location aware switching app.(AndFHEM 2.1.4+)
You can trigger actions based on device states by adding the Device State Locale Plugin. You need to select a device and enter a desired device state. If the device state is found to match the desired state, the condition is met and an action is triggered. This plugin only works using Locale and Tasker.
Using a Locale Plugin you can switch to another AndFHEM connection. This can be used to select a connection based on an available WLAN connection or a network cell. (AndFHEM 2.7.0+)
Tasker allows to receive Intents from external applications and trigger events based on the contents (see Tasker Documentation for details, AndFHEM 2.7.0+).
Broadcasts are only sent if GCM is enabled. The broadcast intents contain the following information:
| Broadcast-Aktion | li.klass.fhem.constants.Actions.EXT_DEVICE_STATE_NOTIFY |
| ACTION | deviceStateChange |
| DEVICENAME | The name of the changed device, i.e. "mat_halogen" |
| STATE_NAME | The name of the changed state. This is always uppercase and usually equals to "STATE". |
| STATE_VALUE | The actual value, i.e. "on". |

Overview Database source and destination
This overview will give you a description of all the sources and destination reading and writing from databases
DBSource
The DBSource is the most common data source for a data flow. It basically connects to a database via ADO.NET and executes a SELECT-statement to start reading the data.
While ADO.NET is reading from the source, data is simutaneously posted into the dataflow pipe.
To initialize a DBSource, you can either hand over a TableDefinition
, a SQL-statement or a tablename.
The DBSource also accepts a connection manager. If no connection manager is specified, the "default" connection manager is used
(which is stored in ControlFlow.CurrentDbConnection
)
Generic approach
The DBSource can be defined with a POCO that matches the data types of the data.
By default, the mapping of column names to properties is resolved by the property name itself. E.g. a column named Value1
would stored in the property with the same name. If you use the ColumnMap
attribute, you can add what column name will be mapped
to the property. If there is no match, the column will be ignored.
Usage example:
public class MySimpleRow {
[ColumnMap("Value1")]
public string Col1 { get; set; }
public int Value2 { get; set; }
}
DBSource<MySimpleRow> source = new DBSource<MySimpleRow>(
$@"select Value1, Value2 from dbo.Test"
);
Non generic approach
Instead of parsing your source data into a object, you can just read all your data in to string array. This is equivalent to DBSource<string[]>
.
E.g.:
DBSource source = new DBSource($@"select Value1, Value2 from dbo.Test");
RowTransformation row = new RowTransformation(
row => {
string value1 = row[0];
string value2 = row[1];
}
);
would have all data from column "Value1" accesable at the first position of the string array and "Value2" at the second position.
DBDestination
Like the DBSource
, the DBDestination
is the common component for sending data into a database. It is initalized with a table name or a TableDefinition
.
The following example would transfer data from the destination to the source, using all the same connection manager (derived from ControlFlow.CurrentDbConnection
):
DBSource<MySimpleRow> source = new DBSource<MySimpleRow>("SourceTable");
DBDestination<MySimpleRow> dest = new DBDestination<MySimpleRow>("DestinationTable");
//Link everything together
source.LinkTo(dest);
//Start the data flow
source.Execute();
dest.Wait()
Sql Server Connections
The DBSource
and DBDestination
can be used to connect via ADO.NET to a sql server.
Use the ConnectionString
object and a SqlConnectionManger
to create a regular ADO.NET connection.
DBSource source = DBSource (
new SqlConnectionManager(new ConnectionString("Data Source=.;Integrated Security=SSPI;Initial Catalog=ETLBox;")),
"SourceTable"
);
MySql Connections
The DBSource
and DBDestination
can be used to connect to a MySql database via the MySql ADO.NET provider.
Use the MySqlConnectionString
object and a MySqlConnectionManger
.
DBSource source = DBSource (
new MySqlConnectionManager(new MySqlConnectionString("Server=<IP_ADDRESS>;Database=ETLBox_ControlFlow;Uid=etlbox;Pwd=etlboxpassword;")),
"SourceTable"
);
Postgres Connections
The DBSource
and DBDestination
can be used to connect to a Postgres database via the Postgres ADO.NET provider.
Use the PostgresConnectionString
object and a PostgresConnectionManger
.
DBDestination dest = DBDestination (
new PostgresConnectionManager(new PostgresConnectionString(""Server=<IP_ADDRESS>;Database=ETLBox_DataFlow;User Id=postgres;Password=etlboxpassword;")),
"DestinationTable"
);
SQLite Connections
The DBSource
and DBDestination
can be used to connect to a SQLite database via the SQLite ADO.NET provider.
Use the SQLiteConnectionString
object and a SQLiteConnectionManger
.
DBSource source = DBSource (
new SQLiteConnectionManager(new SQLiteConnectionString("Data Source=.\\db\\SQLiteControlFlow.db;Version=3;")),
"SourceTable"
);
SMO Connection Manager
The SMOConnectionManager
uses Sql Server Managed Objects to connect to a Sql Server. It allow the use of the GO keyword within your SQL to separate batches.
It can be used with a ConnectionString
.
ControlFlow.CurrentDbConnection = new SMOConnectionManager(new ConnectionString("Data Source=.;Integrated Security=SSPI;Initial Catalog=ETLBox;"));
SqlTask.ExecuteNonQuery("SQL with GO keyword", "CREATE SCHEMA TEST; GO; SELECT 1");
Sql Server ODBC Connections
The DBSource
and DBDestination
also works with ODBC connection to Sql Server. .
You will still use the underlying ADO.NET, but it allows you to connect to SQL Server via ODBC.
DBSource source = DBSource (
new SqlODBCConnectionManager(new ODBCConnectionString(""Driver={SQL Server};Server=.;Database=ETLBox_ControlFlow;Trusted_Connection=Yes")),
"SourceTable"
);
Warning: ODBC does not support bulk inserts like in "native" connections.
The DBDestination
will do a bulk insert by creating a sql insert statement that
has multiple values: INSERT INTO (..) VALUES (..),(..),(..)
Access DB Connections
The ODBC connection to Microsoft Access databases have some more restrictions. ETLBox is based .NET Core and will only
support 64bit ODBC connections. You need also have Microsoft Access 64 bit installed. (The corresponding 64bit ODBC driver for Access can be download
Microsoft: Microsoft Access Database Engine 2010 Redistributable
To create a connection to an Access Database, use the AccessOdbcConnectionManager
and an OdbcConnectionString
.
DBDestination dest = DBDestination (
new AccessOdbcConnectionManager(new OdbcConnectionString("Driver={Microsoft Access Driver (*.mdb, *.accdb)}DBQ=C:\DB\Test.mdb")),
"DestinationTable"
);
Warning: The DBDestination
will do a bulk insert by creating a sql statement using a sql query that Access understands. The number of rows per batch is very limited - if it too high, you will the error message 'Query to complex'. Try to reduce the batch size to solve this.
Note: Please note that the AccessOdbcConnectionManager will create a "temporary" dummy table containing one record in your database when doing the bulk insert. After completion it will delete the table again. This was necessary to simulate a bulk insert with Access-like Sql.

The three polypeptides comprising fibrinogen are encoded by distinct but ancestrally related genes. The domains in fibrinogen are related to domains found in FreP-A and FreP-B from sea cucumber, in scabrous proteins (regulation of neurogenesis) from Drosophila, and in ficolin proteins (lectin activity). Fibrinogen domains originated early in development, and their ability to form intermolecular interactions may be harnessed by different proteins involved in various aspects of cellular function and developmental biology.

From the graphical match in the top (blue) table, you can see that the signatures are all grouped into two InterPro entries for human fibrinogen gamma chain. These entries identify two domains for this protein.
DOMAIN Entries
Ø IPR002181: C-terminal globular domain from fibrinogen chains alpha/beta/gamma, represented by three signatures: PF00147 (PFAM), PS00514 (PROSITE), and SM00186 (SMART).
Ø IPR012290: Coiled coil domain from fibrinogen gamma chain, represented by one signature: G3DSA:<IP_ADDRESS> (Gene3D).
The gamma polypeptide of fibrinogen consists of an N-terminal region that forms part of fibrinogen E domain, followed by an alpha-helical region that forms part of the fibrinogen coiled coil domain, and the C-terminal region that forms part of the fibrinogen D domain (all in conjunction with the Aa and Bb polypeptides). Both the coiled coil (IPR012290) and the C-terminal region forming the D domain (IPR002181) are represented above.
Splice variants
The two yellow tables represent known splice variants for the gamma chain, P02679-1 and P02679-2. Both of these splice variants match the signatures for the C-terminal globular domain, but fail to match the signature for the N-terminal domain. Splice variant P02679-1 comprises about 10% of the fibrinogen molecules in plasma, but is absent from those in platelets.
Structural features
The remaining eight entries in the blue table above give information on the known and predicted structure of this protein. The first seven entries present known structural data from the structural database PDB (green stripe) and the structural classification databases CATH (pink stripe) and SCOP (black stripe) (the names such as 1fzcC3 are derived from the PDB entry upon which they are based, here PDB entry 1fzc, chain C, fragment 3). The graphical match for the PDB entry 1n86 displays the full length of the original PDB entry, here covering about two-thirds of the protein. There are two PDB chains representing this protein, because there are two gamma polypeptides in a fibrinogen molecule. The CATH and SCOP entries break down the PDB data into its structural domains, and providing a structural classification for the protein domain and relating it to other structures in the PDB database.
CATH breaks the fibrinogen gamma chain into three domains:
· <IP_ADDRESS>.9 represents an alpha-helical coiled coil (coiled coil domain)
· <IP_ADDRESS>.2 represents an alpha helix-beta sheet complex (D domain)
· 4.10.530.10.1 represents an irregular structure (D domain)
SCOP breaks the fibrinogen gamma chain into two domains:
· h.1.8.1 represents an alpha-helical coiled coil (coiled coil domain)
·
d.171.1.1
represents an unusual fold consisting of separate alpha and beta regions (D
domain)
The remaining entry is for the structural prediction, MB_P02679, from the homology model database ModBase (yellow stripe). The homology model provides information on the predicted structure for regions of the proteins that have no known structure, here the N-terminal domain that forms part of the E domain in fibrinogen.
Structures
associated with the gamma chain of human fibrinogen can be viewed using
AstexViewer®, which is linked from the Match Table via the logo on the InterPro page (please note, there is
no link directly from this page to the AstexViewer®, therefore you need to go
to the link on the InterPro page for P02679). The AstexViewer® displays the PDB structure with the CATH and
SCOP domains highlighted in yellow. In
the picture below, the CATH domain representing the coiled coil region from one
gamma chain is highlighted in yellow, while the ligands are highlighted in red
attached to the two D domains.

There are
structures available for all three fibrinogen polypeptides from different organisms in the
Protein Data Bank (PDB). A detailed
description and visualisation of the structural features of these proteins can
be found at the PDB ‘Molecule of the Month’.
The crystallographic structures of fibrinogen and fibrin proteins have
provided insight into the assembly of blood clots.


October 2013 ngx_pagespeed Security Update.
Overview
All versions of ngx_pagespeed prior to <IP_ADDRESS> are subject to critical cross-site scripting (XSS) vulnerability CVE-2013-6111. Depending on configuration this may permit a hostile third party to execute JavaScript in users' browsers in the context of the domain running ngx_pagespeed, which could permit theft of users' cookies or data on the site.
Because of the severity of the problem, users of affected versions are strongly encouraged to immediately update ngx_pagespeed or apply the workaround below.
To be notified of further security updates subscribe to the announcements mailing list.
Solutions
Users of affected versions should either apply the workaround or update to version <IP_ADDRESS> or later.
Workaround
The vulnerability requires access to /ngx_pagespeed_statistics
,
/ngx_pagespeed_global_statistics
, or
/ngx_pagespeed_message
. Prohibiting access to these in
your nginx.conf
is sufficient to keep it from being exploited.
Note that it is not enough to restrict these pages to trusted users; they must
not be accessible to anyone. Example workaround configuration:
location /ngx_pagespeed_statistics { deny all; } location /ngx_pagespeed_global_statistics { deny all; } location /ngx_pagespeed_message { deny all; }
While ngx_pagespeed and mod_pagespeed are very similar, this workaround is not sufficient for mod_pagespeed. If you also run PageSpeed in Apache please follow the recommendations in the October 2013 mod_pagespeed Security Update.
Update
Users unable to apply the workaround, or who want continued access to the
informational data provided by /ngx_pagespeed_statistics
or /ngx_pagespeed_message
should update to an unaffected version.
This requires building nginx with the updated ngx_pagespeed module and
installing it in place of the current version. See
the build
instructions.
Users having difficulty applying these updates or with other questions should write to the discussion group.

In 8th grade, I first learned about 3d printing from my librarian. She handed me the first 3d model I had ever seen or touched: a small gyroscope model. The fact that something could go from an idea to a 3d model to a physical object was amazing, and I was instantly hooked. Once I got to high school I had access to some basic 3d printers. I was upset, however, that I could never tinker with them and improve them as they were school property. So, I saved up over the course of a few months and bought a cheap 200$ 3d printer from a random vendor in China. Depsite its cheap price, I still use it to this day.
Here's a few notes about how I 3d print:
Check out some of my previous 3d printed works down below.


Select how you want uncommitted changes to be treated when you perform a project update:
- Stash:
local changes will be saved to a git
stash. This is useful if you need to apply patches with stashed changes outside IntelliJ IDEA, as they
are generated by Git itself.
- Shelve:
IntelliJ IDEA will put local changes to a shelf.
Shelving is done by IntelliJ IDEA, and patches generated from shelved changes are normally applied inside
IntelliJ IDEA.
