In computer science , particularly in human computer interaction , presentation semantics specify how a particular piece of a formal language is represented in a distinguished manner accessible to human senses , usually human vision. For example, saying that code nowiki bold ... bold nowiki code must render the text between these constructs using some bold typeface is a specification of presentation semantics for that syntax . An example of interactive presentation semantics is defining the expect behavior of a Hyperlink hypertext link on a suitable syntax. Many markup languages like HTML , CSS , DSSSL , XSL FO or troff have presentation semantics, but others like XML , XLink and XPath do not. ref H. P.

Application oriented networking AON involves network devices designed to aid in computer to computer application integration. Application oriented networking was popularized by Cisco Systems in response to increasing use of XML messaging combined with related standards such as XSLT , XPath and XQuery to link miscellaneous applications, data sources and other computing assets. Many of the operations required to mediate between applications, or to monitor their transactions, can be built into network devices that are optimized for the purpose. The rules and policies for performing these operations, also expressed in XML, are specified separately and downloaded as required. Cisco has adopted the AON acronym as the name of a family of products that function in this way.

Streaming Transformations for XML STX is an XML transformation language intended as a high speed, low memory consumption alternative to XSLT version 1.0 and 2.0. Current work on XSLT 3.0 includes Streaming capabilities. Overview STX is an XML standard for efficient processing of stream based XML. As we will discover, XSLT is not well suited to stream based processing, and STX fills this niche. Conventional XML processing involves loading the entire XML document into memory for use. This is as opposed to Simple API for XML SAX which Streaming XML streams XML events such as open element close element text node and so on so that other software that can begin interpreting these immediately before the end of the file is reached. Unfortunately some software can t effectively use XML fragments this way and must build up the whole document to begin processing. So is the case with XSLT. Because XSLT s XPath can select any node throughout the document it must have the entire document available in memory. Understandably, this could be perceived as a bottleneck. STX only allows queries immediately surrounding the current node so it can quickly start transforming and outputting SAX event nodes as they arrive. As it can discard nodes immediately after processing the memory use is significantly lower than that of XSLT. Having a limited query scope is a defining characteristic of STX. This architectural decision intentionally marginalises STX as a niche language. Indeed, it would be wrong to say that STX is a general purpose transformation language however, if your transformation needs can be met by STX then it s an efficient and smart choice. Specifications STX s query language is called STXPath and is based on XPath 2.0 . Implementations of STX are available in Java programming language Java and Perl . Similar projects Unlike STX which is declared using an XML syntax, these two projects associate SAX events with Callback computer science callback functions Xineo OAX SAX Adapter E ... more details
WS BaseNotification is a web services specification which defines the interface WS Notification clients consumers and servers producers should expose. Subscription The subscribe method exposed through the NotificationProducer interface allows consumers to register their interest in WS Topics topics using the method, it is also possible to set a subscription expiry time and a custom Boolean logic boolean filter. A subscription to a topic implies a subscription to all children of that topic in the topic space . A useful feature of WS BaseNotification is that the client calling subscribe can subscribe on behalf of the consumer this is very useful in areas such as grid computing , where often subscriptions require specific privileges , but the service with that privilege wishes to defer processing to another service. Subscription filters An XPath filter can be provided at subscribe time that narrows down the notifications a consumer will receive. Before any notification is dispatched, the producer will run the XPath expression if the expression does not match the notification being processed then that consumer will not receive a notification Pausing resuming subscriptions The PauseSubscription and ResumeSubscription methods exposed through the SubscriptionManager interface allow consumers to temporarily suspend their subscriptions and allows the resumption of notifications. Subscriptions can be resumed with one of the following policies regarding missed notifications Send notification on next new change a similar effect to unsubscribing and then resubscribing. Send the last notification that the consumer would have received had the subscription not been paused. Send all the notifications that the consumer missed out on while the subscription was paused. Unsubscription As its name implies, the unsubscribe method allows a consumer to cancel an existing subscription. Available in 1.3 Notification The consumer s notify method exposed through the NotificationConsumer interfa ... more details
