Emery says Torreira ‘needs to improve’ but backs midfielder to have big Arsenal future
by FSA EditorLucas Torreira “needs to improve” but is sure to be an important player for Arsenal, according to head coach Unai Emery.
Unai Emery insists Lucas Torreira has a bright future at Arsenal despite the midfielder’s apparent disapproval of his new role in midfield.
Torreira impressed last season but has started just four of 12 Premier League matches this term amid rumoured transfer interest from AC Milan and Napoli.
His agent, Pablo Bentancur, recently admitted the tenacious Uruguayan was unhappy with having to playing higher up the pitch than usual.
Emery thinks Torreira must hone his tactical nous to be suitable for the base of midfield but still expects him to enjoy a long and fruitful career in north London.
“He is a very good player, important for us, and his focus needs to be with us 100 per cent,” Emery said.
“He has very big commitment and very good behaviour. He has a very big future here but he needs to improve. He has to learn in some situations, individually to help us, to do better. It’s one process.”
Torreira started the club’s last fixture before the international break, a 2-0 loss to Leicester City, but faces a fight to hold his spot for Saturday’s match against Southampton as Granit Xhaka returns to selection contention.
Emery hopes video analysis sessions will strengthen the 23-year-old’s understanding of what Arsenal require in the engine room.
“He played well last year but this year he’s not being consistent,” the Gunners boss said.
“My challenge to him is to improve, to do better with some tactical issues on the pitch and above all be consistent.
“I spoke with him on Wednesday and Thursday. I showed him some movies about his best performances with us and how he can improve.
“He is young, his process here is starting and he started playing in the Premier League last year and he progressed, but this year again he needs to progress.”


Versioning
It is inevitable that functions will need to be added, removed, or change over the lifetime of an application. Durable functions allows chaining function together in ways that was not previously possible, and this has significant implications on versioning.
Breaking Changes
There are several examples of breaking changes to be aware of. The most common ones are discussed below. The main theme behind all of them is that both new and existing function orchestrations are immediately impacted by changes to function code.
Changing activity function signatures
A signature change refers to a change in the name, input, or output of a function. If this kind of change is made to an activity function, it could potentially break the orchestrator function which depends on it. Furthermore, it is often not possible to simply update the orchestrator function to accommodate this change, because updating the logic of an orchestrator function could break existing in-flight instances.
As an example, suppose we have the following function.
[FunctionName("FooBar")]
public static Task Run([OrchestrationTrigger] DurableOrchestrationContext context)
{
bool result = await context.CallActivityAsync<bool>("Foo");
await context.CallActivityAsync("Bar", result);
}
This simplistic function takes the results of Foo and passes it to Bar. Let's assume we need to change the return value of Foo from bool
to int
to support a wider variety of result values. The result looks like this:
[FunctionName("FooBar")]
public static Task Run([OrchestrationTrigger] DurableOrchestrationContext context)
{
int result = await context.CallActivityAsync<int>("Foo");
await context.CallActivityAsync("Bar", result);
}
This change works fine for all new instances of the orchestrator function but will break any in-flight instances. For example, consider the case where an orchestration instance calls Foo, gets back a boolean value and then checkpoints. If the signature change is deployed at this point, the checkpointed instance will fail immediately when it resumes and replays the call to context.CallActivityAsync<int>("Foo")
. This is because the result in the history table is bool
but the new code tries to deserialize it into int
.
This is just one of many different ways that a signature change can break existing instances. In general, if an orchestrator needs to change the way it calls a function, then the change is very likely to be problematic.
Changing orchestrator logic
The other class of versioning problems come from changing the orchestrator function code in a way that confuses the replay logic for in-flight instances.
Consider the following orchestrator function:
[FunctionName("FooBar")]
public static Task Run([OrchestrationTrigger] DurableOrchestrationContext context)
{
bool result = await context.CallActivityAsync<bool>("Foo");
await context.CallActivityAsync("Bar", result);
}
Now let's assume you want to make a seemingly innocent change to add another function call.
[FunctionName("FooBar")]
public static Task Run([OrchestrationTrigger] DurableOrchestrationContext context)
{
bool result = await context.CallActivityAsync<bool>("Foo");
if (result)
{
await context.CallActivityAsync("SendNotification");
}
await context.CallActivityAsync("Bar", result);
}
This change adds a new function call to SendNotification between Foo and Bar. There are no signature changes. The problem arises when an existing instance resumes from the call to Bar. During replay, if the original call to Foo returned true
, then the orchestrator replay will call into SendNotification which is not in its execution history. As a result, the Durable Task Framework will fail with a NonDeterministicOrchestrationException
because it encountered a call to SendNotification when it expected to see a call to Bar.
Mitigation Strategies
There are a few different ways to deal with versioning challenges, which we'll discuss here.
Do nothing
This is the default approach (obviously) and will result in in-flight orchestration instances failing when they encounter a breaking change. New instances will not be affected, assuming there aren't any new bugs introduced in the new version.
Whether this is a problem depends on the importance of your in-flight instances. If you are in active development and don't care about in-flight instances, then this might be good enough. However, you will need to deal with exceptions and errors which will appear in your diagnostics pipeline. If you care about any of these things, then you'll want to look at other options.
Stop all in-flight instances
Another option is to simply stop all in-flight instances. This can be done by clearing the contents of the internal control-queue and workitem-queue queues. The instances will be forever stuck where they are, but they will not clutter your telemetry with failure messages. This is ideal in rapid prototype development.
Warning
The details of these queues may change over time, so you must not rely this technique for production workloads.
Side-by-side deployments
The most fail-proof way to ensure that breaking changes can be deployed safely is by deploying them side-by-side with your older versions. This can be done using one of the following techniques:
- Deploy all the updates as entirely new functions (new names).
- Deploy all the updates as a new function app with a different storage account.
- Deploy a new copy of the function app but with an updated
TaskHub
name.
Of all the options above, the recommended option is to deploy a new version of the function app with a different TaskHub
name. The task hub can be configured in the host.json as follows:
{
"durableTask": {
"HubName": "MyTaskHubV2"
}
}
By default this value is DurableFunctionsHub
and all Azure Storage entities are named based on the HubName
configuration value. By giving the task hub a new name, you ensure that separate queues and history table are created for the new version of your application.
To ensure that existing instances can continue to run using old logic while new instances use the new logic, it is recommended to deploy the new version of the function app to a new Deployment Slot. Deployment slots allow you to run multiple copies of your function app side-by-side with exactly one of them as the active production slot. When you are ready to expose the new orchestration logic to your existing infrastructure, it can be as simple as a swapping the new version into the production slot.
Note
This strategy works best when using HTTP triggers and/or webhooks to trigger and interact with orchestrator functions. When using non-HTTP triggers (e.g. queues or Event Hubs), you will want to have the trigger definition derive from an app setting which gets updated as part of the swap operation.

Card Payments¶
Supported Transaction Types¶
This payment method supports the following transaction types:
WDECTransactionTypeAuthorization
- places the account holder's funds on hold, pending future capture, re-authorization or void transaction.WDECTransactionTypeAuthorizationOnly
- verifies the validity of account holder's card, but does not leave an authorized amount.WDECTransactionTypePurchase
- charges the account holder's card and immediately transfers the reserved amount.WDECTransactionTypeReferencedAuthorization
- places the account holder's funds on hold, pending future capture, re-authorization or void transaction. References a previousWDECTransactionTypeAuthorization
transaction.WDECTransactionTypeReferencedPurchase
- charges the account holder's card and immediately transfers the reserved amount. References a previousWDECTransactionTypePurchase
transaction.WDECTransactionTypeTokenize
- provides a unique token which represents the tokenized card data. This token then can be used in future transactions.
Basic Setup¶
Cocoapods¶
Add to your app's Podfile
subspecs:
1 2 3 | pod 'paymentSDK/Card', '~> 3.0.0' # just by adding card scanner subspec consumers get option to scan card pod 'paymentSDK/CardScanner', '~> 3.0.0' |
Camera Permission¶
To make sure Card Scanner has permission before using camera to scan card, follow the steps in Apple documentation. You need to include NSCameraUsageDescription
in your app's Info.plist
file.
Basic Card Payment¶
This is a code example for a basic card payment:
1 |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 | // 1. Initialize client object // Parameters (hostname, merchantAccountID) may come from server to make it configurable. NSError *error = nil; self.client = [[WDECClient alloc] initWithHostname:hostname error:&error]; if (error) { // the device is checked during initialization for jailbreak. // It is risky to make payments on jailbroken devices. return; } // 2. Initialize payment object and set mandatory properties // Parameters (amount, currency, transactionType) shall be sent to server for validation or just provided by server // and used to generate signature. Signature MUST be generated on server side. // Signature doc: https://document-center.wirecard.com/display/PTD/Signature+v2 // Secret Key shall never be stored in application. WDECCardPayment *payment = [WDECCardPayment new]; payment.merchantAccountID = merchantAccountID; // provided by merchant support payment.requestID = requestID; // generated on server; unique for merchantAccountID payment.amount = [NSDecimalNumber decimalNumberWithMantissa:199 exponent:-2 isNegative:NO]; payment.currency = @"EUR"; payment.transactionType = WDECTransactionTypePurchase; payment.signature = signature; // 3. Create payment completion block to handle response @weakify(self); WDECCompletionBlock completionBlock = ^(WDECPaymentResponse * _Nullable response, NSError * _Nullable error) { @strongify(self); // for each failure error object is provided; if (error) { return; } [self handleResponse:response]; } // 4. Trigger the payment [self.client makePayment:payment withCompletion:completionBlock]; |
Note: You can set optional parameters after the payment object is created. Check the API documentation:WDECCardPayment and for more details.
Token payment¶
This is a code example for a card payment which uses a card token (obtained from a previous transaction):
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | val cardPayment = CardPayment( signature, requestID, merchantID, transactionType, amount, currency ) // for enabling animated card layout cardPayment.animatedCardPayment = true val cardToken = CardToken() cardToken.tokenId = "12345678901111" cardPayment.cardToken = cardToken cardToken.tokenUsageIndicator = true cardToken.requireSecurityCode = true Client(context = this, url = "https://api-test.wirecard.com", requestTimeout).startPayment(cardPayment) |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | cardPayment = new CardPayment.Builder() .setSignature(signature) .setRequestId(requestID) .setMerchantAccountId(merchantID) .setTransactionType(transactionType) .setAmount(amount) .setCurrency(currency) .build(); // for enabling animated card layout cardPayment.setAnimatedCardPayment(true); CardToken cardToken = new CardToken(); cardToken.setTokenId("12345678901111"); cardPayment.setCardToken(cardToken); cardPayment.setRequireSecurityCode(true); cardPayment.setTokenUsageIndicator(true); new Client(context, "https://api-test.wirecard.com", requestTimeout).startPayment(cardPayment); |
Card Field¶
Card Field is a feature where card information (card number, expiration date and CVV) is entered into a single, dynamically changing field instead of multiple separate ones.
Here's example code for a card payment using this feature:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 | class KotlinCardFormActivity : AppCompatActivity(), Observer<PaymentResponse> { private val mContext = this private val mPaymentObjectProvider = PaymentObjectProvider() private lateinit var cardFieldFragment: CardFieldFragment override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_card_form) cardFieldFragment = CardFieldFragment.Builder().build() supportFragmentManager .beginTransaction() .add(R.id.card_field_container, cardFieldFragment) .commit() cardFieldFragment .getEventObserver() .subscribe { state -> Log.i("event", state.toString()) } } fun onSubmitButtonClicked(view: View) { if (cardFieldFragment.getCardBundle() != null) { Client(this, URL_EE_TEST, null, REQUEST_TIMEOUT).startPayment(getCardFormPayment(cardFieldFragment.getCardBundle())) findViewById<View>(R.id.progress).visibility = View.VISIBLE } else { Toast.makeText(mContext, "Card bundle is null!", Toast.LENGTH_SHORT).show() } } fun getCardFormPayment(cardBundle: CardBundle): CardFormPayment { val merchantID = "merchant_id" val secretKey = "secret_key" val requestID = UUID.randomUUID().toString() val transactionType = TransactionType.PURCHASE val amount = BigDecimal(5) val currency = "EUR" val signature = SignatureHelper.generateSignature(timestamp, merchantID, requestID, transactionType.value, amount, currency, secretKey) val cardFormPayment = CardFormPayment.Builder() .setSignature(signature) .setMerchantAccountId(merchantID) .setRequestId(requestID) .setAmount(amount) .setTransactionType(transactionType) .setCurrency(currency) .setCardBundle(cardBundle) .build() val accountHolder = AccountHolder("John", "Doe") cardFormPayment.accountHolder = accountHolder return cardFormPayment } override fun onObserve(paymentResponse: PaymentResponse) { runOnUiThread { Toast.makeText(mContext, ResponseHelper.getFormattedResponse(paymentResponse), Toast.LENGTH_SHORT).show() findViewById<View>(R.id.progress).visibility = View.GONE } } } |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 | public class CardFormActivity extends AppCompatActivity implements Observer<PaymentResponse> { private Context mContext = this; private PaymentObjectProvider mPaymentObjectProvider = new PaymentObjectProvider(); CardFieldFragment cardFieldFragment; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_card_form); cardFieldFragment = new CardFieldFragment.Builder().build(); getSupportFragmentManager() .beginTransaction() .add(R.id.card_field_container, cardFieldFragment) .commit(); cardFieldFragment .getEventObserver() .subscribe( state -> { Log.i("event", state.toString()); } ); } public void onSubmitButtonClicked(View view) { if(cardFieldFragment.getCardBundle() != null) { new Client(this, URL_EE_TEST, null, REQUEST_TIMEOUT).startPayment(getCardFormPayment(cardFieldFragment.getCardBundle())); findViewById(R.id.progress).setVisibility(View.VISIBLE); }else { Toast.makeText(mContext, "Card bundle is null!", Toast.LENGTH_SHORT).show(); } } public CardFormPayment getCardFormPayment(CardBundle cardBundle) { String merchantID = "merchant_id"; String secretKey = "secret_key"; String requestID = UUID.randomUUID().toString(); TransactionType transactionType = TransactionType.PURCHASE; BigDecimal amount = new BigDecimal(5); String currency = "EUR"; String signature = SignatureHelper.generateSignature(timestamp, merchantID, requestID, transactionType.getValue(), amount, currency, secretKey); CardFormPayment cardFormPayment = new CardFormPayment.Builder() .setSignature(signature) .setMerchantAccountId(merchantID) .setRequestId(requestID) .setAmount(amount) .setTransactionType(transactionType) .setCurrency(currency) .setCardBundle(cardBundle) .build(); AccountHolder accountHolder = new AccountHolder("John", "Doe"); cardFormPayment.setAccountHolder(accountHolder); return cardFormPayment; } @Override public void onObserve(PaymentResponse paymentResponse) { runOnUiThread(() -> { Toast.makeText(mContext, ResponseHelper.getFormattedResponse(paymentResponse), Toast.LENGTH_SHORT).show(); findViewById(R.id.progress).setVisibility(View.GONE); } ); } } |
Additional Options for Card Field¶
You can set additional options for Card Field throughCardFieldFragment.Builder
:
SetSupportedCardBrands
- sets allowed card brands (providers)setExpirationDate
- used in token paymentssetRequestFocus
- sets screen focus (after the card form loads)setHideCardIcon
- hides provider icons (VISA, Maestro, etc.)setToken
- used in token paymentssetMaskedCardNumber
- used in token paymentssetCardBrand
- sets the card brand/providersetTextSize
- changes text sizesetLocale
- changes the payment localesetNativeLocale
- changes the payment locale (UI only)
Token Payment with Card Field¶
The payment object is identical to a normal card field payment (like the example above), but you need to include the card token.
1 2 3 4 5 6 7 | ... val cardToken = CardToken() cardToken.tokenId = "12345678901111" cardPayment.cardToken = cardToken cardToken.tokenUsageIndicator = true cardToken.requireSecurityCode = true ... |
1 2 3 4 5 6 7 8 | ... CardToken cardToken = new CardToken(); cardToken.setTokenId("12345678901111"); cardPayment.setCardToken(cardToken); cardPayment.setRequireSecurityCode(true); cardPayment.setTokenUsageIndicator(true); ... |
Customizing Visuals¶
To change colors within the SDK, override the default color values in the .xml
file.
Color Resources¶
Changing any of these will affect every module used in the SDK:
wd_ecom_color_main
- color tint for icons, header and submit button gradient start color
wd_ecom_color_main_light
- header and submit button gradient end color
wd_ecom_color_main_alpha80

- pay button text color
wd_ecom_color_main_background
- background color for main view
wd_ecom_color_error
- used for all text input layouts to modify error text color including the edit text line
Changing Fonts¶
To change fonts, add the font path to the payment object:
1 2 3 4 5 6 7 8 9 10 11 12 13 | val cardPayment = CardPayment( signature, timestamp, requestID, merchantID, transactionType, amount, currency ) cardPayment.fontPath = "fonts/myFont.otf" Client(context = this, url = "https://api-test.wirecard.com", requestTimeout).startPayment(cardPayment) |

BodyParser
public class BodyParser: RouterMiddleware
The BodyParser
parses the body of the request prior to sending it to the handler. It reads the Content-Type of the message header and populates the RouterRequest
body field with a corresponding ParsedBody
enumeration.
In order for the BodyParser to be used it must first be registered with any routes that are interested in the ParsedBody
payload.
ParsedBody enumeration:
The mappings from the incoming Content-Type to an internal representation of the body are as follows:
.json([String: Any]) // "application/json"
.text(String) // "text/*"
.urlEncoded([String:String]) // "application/x-www-form-urlencoded"
.multipart([Part]) // "multipart/form-data"
.raw(Data) // Any other Content-Type
Each case has a corresponding convenience property, e.g. asURLEncoded: [String:String]
, for accessing the associated data.
Note: If you have not declared a Content-Type header, ParsedBody
will be nil
.
Usage Example:
In this example, all routes to the BodyParser middleware are registered to the BodyParser
middleware. A request with application/json
, ContentType header is received. It is then parsed as JSON and the value for name
is returned in the response.
router.all("/name", middleware: BodyParser())
router.post("/name") { request, response, next in
guard let jsonBody = request.parsedBody?.asJSON else {
next()
return
}
let name = jsonBody["name"] as? String ?? ""
try response.send("Hello \(name)").end()
}
Note: When using Codable Routing in Kitura 2.x the BodyParser should not be registered to any codable routes (doing so will log the following error No data in request. Codable routes do not allow the use of a BodyParser.
and the route handler will not be executed).
-
Initializes a BodyParser instance. Needed since default initalizer is internal.
Usage Example:
let middleware = BodyParser()
Declaration
Swift
public init()
-
This function is called by the Kitura
Router
when an incoming request matches the route provided when the BodyParser was registered with theRouter
. It performs the parsing of the body content usingparse(_:contentType)
. We don’t expect a user to call this function directly.Declaration
Swift
public func handle(request: RouterRequest, response: RouterResponse, next: @escaping () -> Void) throws
Parameters
request
The
RouterRequest
object used to work with the incoming HTTP request.response
The
RouterResponse
object used to respond to the HTTP request.next
The closure called to invoke the next handler or middleware associated with the request.
-
This function is called by the Kitura
Router
when an incoming request matches the route provided when the BodyParser was registered with theRouter
. Themiddleware.handle(...)
function will parse the body content of an incoming request using this function. A user can call this function directly but ordinarily won’t need to.Usage Example:
In this example, the body of the request is parsed to be of the passed in contentType.
request.body = BodyParser.parse(request, contentType: contentType)
Declaration
Swift
public class func parse(_ message: RouterRequest, contentType: String?) -> ParsedBody?
Parameters
message
Message coming from the socket.
contentType
The content type as a String.
Return Value
The parsed body.
-
Read the body data of the request.
Usage Example:
In this example, the body of the request is read into a constant (called bodyData) using an instance of
RouterRequest
(called request).let bodyData = try readBodyData(with: request)
Throws
Socket.Error if an error occurred while reading from a socket.Declaration
Swift
public class func readBodyData(with reader: RouterRequest) throws -> Data
Parameters
with
The socket reader.
Return Value
The body data associated with the request.

SensorDX is an open-source standard-compliant software system that implements novel machine learning methods for automated quality control (QC) of hydro-meteorological sensor network data.
The goal of this project is to achieve a much higher degree of automated QC to permit a smaller number of experts to manage a much larger number of sensors.
Throughout this documentation, we have highlighted our powerful and robust API behind the SensorDX Dashboard (SDD), the SensorDX Issue Tracker (SDI), and SensorDX Sensor Management System (SMS).
Also, we went out of our way to give you an overview of the powerful and ultimate SensorDX algorithm that makes automated quality control possible. Who would have thought managing millions of sensors could be this fun? You're welcome :-)

Good-quality XSD
Structure (define/include) preserving
Approximate where necessary
Useful rather than perfect
Build RELAX NG object model
Convert RELAX NG object model to intermediate form
Perform transformations on intermediate form
Generate XSD from intermediate form
Schema language between RELAX NG and XSD
Abstract, no syntax
No mixed element/attribute content models
Clean, simple semantics
Schema structure more controlled than RELAX NG
Simple type definition associates local name with simple type
Attribute group definition associates local name with attribute use
Group definition associates local name with particle
Start declaration declares particle that document element must match
Include references a schema
Order of components not semantically significant
Simple type definitions, attribute group definitions, group definitions have distinct symbol spaces
Definitions are named with local names not QNames
Builtin simple types do not have simple type definitions
No target namespace associated with a schema
No complex type declarations, element declarations or attribute declarations
Restriction contains the name of builtin simple type and list of facets
List contains a simple type and a minimum/maximum number of occurrences
Union contains a list of simple types
Reference contains a local name referring to a simple type definition
Element contains an expanded QName and a complex type
Wildcard element contains a wildcard
Repeat contains a particle and a minimum/maximum number of occurrences
Sequence contains one or more particles
Choice contains one or more particles
Interleave contains one or more particles
Reference contains a local name referring to a group definition
Complex content contains attribute use, a particle, a mixed flag
Simple content contains attribute use, a simple type
Attribute contains an expanded QName and a simple type
Optional attribute contains an attribute and a default value
Wildcard attribute contains a wildcard
Attribute group contains a list of zero or more attributes
Attribute use choice contains a list of one or more attribute uses
Reference contains a local name referring to an attribute group definition
Positive/negative flag
Set of namespace URIs
Set of excluded expanded QNames
Flags computed based on possible matches of the pattern
empty says if there is a match whose content is empty
text says if there is a match whose content includes a text node that is matched against a text pattern
data says if there is a match whose content includes a text node that is matched against a data, value or list pattern
attribute says if there is a match that includes an attribute
element says if there a match whose content includes an element
Sufficient to allow conversion to intermediate form
Can compute flags for patterns from subpatterns
A pattern can be converted in three ways:
A pattern may be converted to a particle
A pattern may be converted to a simple type
A pattern may be converted to an attribute use
A single pattern may be converted both to a particle or a simple type and to an attribute use
element
patterns are treated like
empty
when converting to an attribute use
attribute
patterns are treated like
empty
when converting to a particle or simple
type
A name class is converted to:
a set of expanded QNames
a wildcard
Split name class into wildcard and list of expanded names
Generate wildcard element particle for wildcard
Generate element particle for each expanded name by converting body of element pattern to a complex type
Combine with choice particle
If body has element flag, then use a complex type with complex content and convert body to a particle
Mixed if body has either data or text flag
If body has data flag but neither text nor element flag, then use a complex type with simple content and convert body to a simple type
In addition, convert body to an attribute use
If body has attribute flag, then generate an attribute group definition by converting body to an attribute use
If body has element flag, then generate a group definition by converting body to a particle
If body has data flag but neither text nor element flag, then generate a simple type definition by converting body to simple type
Intermediate form like XSD not RELAX NG
Compute minimum and maximum number of tokens in list
Compute union of simple types of possible members of list
Transform out attribute choice
Transform out interleave except where XSD allows it
Combine attribute wildcards
Combine unions of simple types with enumeration facet
Assign target namespace to each file in intermediate schema
Choose or create principal file for every namespace
Determine which attributes, element particles need to be moved
Determine which negative wildcards need to be moved
Determine which attributes, element particles should be global
Null namespace needs special treatment
Identify cases where complex type can be used instead of
Simple type definition and optionally attribute group definition, or
Group definition and optionally attribute group definition
All references must be such that they can turn into
the type of an element
the base type of a complex type extension
Take advantage of XSD shorthands
Generate complex type definitions
Generate global element/attribute declarations
Generate bridging definitions for non-global moved elements/attributes
Generate bridging definitions for negative wildcards
Deal with attribute wildcards
Avoid violating unique particle attribution constraint
Avoid violating element declarations consistent constraint
Take advantage of substitution groups
Better handling of interleave
Inform user about all approximations
Generate annotations using eg Schematron to make approximations exact
Handle RELAX NG overrides using redefine

Stack Components¶
Amazon CloudFormation¶
This allows us to store the cloud stack as code, making it easily reproducible and editable on a large scale. Each cloud stack component is described as a JSON object, which is then read by CloudFormation to generate full cloud system.
Amazon EC2¶
This is AWS’s virtual server and computing service. It is the underlying resource behind most computing services that AWS offers. GWearCloud does not directly interact with EC2 instances, but rather uses services that help to automate and manage EC2 instances.
 This allows for lower costs, as well as scalability. This is used for each API behaviour code, as well as CloudFormation setup scripts.
Amazon ECS¶
This is used to create containerised apps that are run on an Amazon EC2 instance. Containerisation allows for distributed computing, as well as scalable app proceses.
Amazon S3¶
This is used to host the Lambda function deployable ZIP files. These deployables are used by the CloudFormation template to automatically set up Amazon Lambda.
Amazon RDS¶
This is a service that allows for a managed relational database. In the case of GWearCloud, RDS is used for a PostgreSQL database that contains all the sensor data.
Amazon API Gateway¶
API Gateway is the main way to interact with the database, a decision made for security. By providing an abstracton layer from directly using SQL, GWearCloud prevents malicious database actions.
