Last Call: JSON-LD 1.0 Processing Algorithms and API

2013-05-16T13:58:33Z

The RDF Working Group has published a Last Call Working Draft of JSON-LD 1.0 Processing Algorithms and API. This specification defines an Application Programming Interface (API) and a set of algorithms for programmatic transformations of JSON-LD documents.

Last Call: Indexed Database API

2013-05-16T13:53:57Z

The Web Applications Working Group has published a Last Call Working Draft of Indexed Database API. This document defines APIs for a database of records holding simple values and hierarchical objects. Each record consists of a key and some value. Moreover, the database maintains indexes over records it stores. An application developer directly uses an API to locate records either by their key or by using an index. A query language can be layered on this API. An indexed database can be implemented using a persistent B-tree data structure. Comments are welcome through 07 June.

Two Drafts Published by the System Applications Working Group

2013-05-16T13:51:11Z

The System Applications Working Group has published two Working Drafts today:

The app: URI scheme. This specification defines the app: URI scheme and rules for dereferencing an app: URI, which can be used to address resources inside a package (e.g., a packaged application). The dereferencing model relies on HTTP semantics to return resources in a manner akin to a HTTP GET request. Doing so allows this URI scheme to be used with other technologies that rely on HTTP responses to function as intended, such as XHR.
Messaging API. This specification defines a System Level API which offers a simple interface to get access to mobile messaging services. A typical use case of the Messaging API is the implementation of a messaging client application that allows the user to send SMS and MMS messages as well as to access and manage the received SMS and MMS messages.
