8 December 2016 The  Web Performance Working Group  invites implementation of the Candidate Recommendation of  Performance Timeline Level 2 . This specification extends the High Resolution Time specification by providing methods to store and retrieve high resolution performance metric data. Accurately measuring performance characteristics of web applications is an important aspect of making web applications faster. This specification defines the necessary Performance Timeline primitives that enable web developers to access, instrument, and retrieve various performance metrics from the full lifecycle of a web application.

2 December 2016 The W3C Advisory Committee has  elected  the following people to the  W3C Technical Architecture Group  (TAG): Travis Leithead (Microsoft), Sangwhan Moon (Odd Concepts) and Alex Russell (Google), who all begin 2-year terms on 1 February 2017. The number of nominees being equal to the number of available seats, the nominees were thereby elected. There remains one seat for appointment by the Director. Travis, Sangwhan and Alex join co-Chair Tim Berners-Lee and continuing participants David Baron (Mozilla Foundation), Andrew Betts (Financial Times / Nikkei), Daniel Appelquist (W3C Invited Expert; co-Chair) and Peter Linss (HP; co-Chair). Yves Lafon continues as staff contact. W3C thanks Mark Nottingham (Akamai) whose term ends at the end of January 2017, for his contributions. The mission of the TAG is to build consensus around principles of Web architecture and to interpret and clarify these principles when necessary, to resolve issues involvi...

22 November 2016 The  Web Annotation Working Group  has published a Candidate Recommendation for two documents: Web Annotation Data Model : This specification describes a structured model and format, in JSON, to enable annotations to be shared and reused across different hardware and software platforms. Common use cases can be modeled in a manner that is simple and convenient, while at the same time enabling more complex requirements, including linking arbitrary content to a particular data point or to segments of timed multimedia resources. Web Annotation Vocabulary : This specifies the set of RDF classes, predicates and named entities that are used by the Web Annotation Data Model. It also lists recommended terms from other ontologies that are used in the model, and provides the JSON-LD Context and profile definitions needed to use the Web Annotation JSON serialization in a Linked Data context. This is a re-publication, without substantial change, of the Candida...

25 October 2016 The  CSS Working Group  has published a First Public Working Draft of the  CSS Table Module Level 3 . This CSS module defines a two-dimensional grid-based layout system, optimized for tabular data rendering. In the table layout model, each display node is assigned to an intersection between a set of consecutive rows and a set of consecutive columns, themselves generated from the table structure and sized according to their content.

25 October 2016  The  Spatial Data on the Web WG , a collaboration between W3C and the  OGC , has today published two documents. The  Use Cases & Requirements  document is believed to be complete and underpins the WG’s considerable scope, motivating 3 standards in addition to today’s other publication, the  Spatial Data on the Web Best Practices . The latter has been rewritten substantially to build expressly on the more general  Data on the Web Best Practices , currently in  CR . The aim is to provide guidance that bridges the gap between the practices and mindsets in the two communities so that the Web is better able to make sense of location and geospatial systems are better able to benefit from non-spatial data on the Web. A good example of this can be seen in yesterday’s  announcement by Ireland’s mapping agency  that their geospatial information is now available as Linked Data. Driven largely by geospatial specialists,...

The  Web Annotation Working Group  has published a Candidate Recommendation for three documents: Web Annotation Data Model : This specification describes a structured model and format, in JSON, to enable annotations to be shared and reused across different hardware and software platforms. Common use cases can be modeled in a manner that is simple and convenient, while at the same time enabling more complex requirements, including linking arbitrary content to a particular data point or to segments of timed multimedia resources. Web Annotation Vocabulary : specifies the set of RDF classes, predicates and named entities that are used by the Web Annotation Data Model. It also lists recommended terms from other ontologies that are used in the model, and provides the JSON-LD Context and profile definitions needed to use the Web Annotation JSON serialization in a Linked Data context. Web Annotation Protocol : This document describes the transport mechanisms for creating and man...

W3C published  the  report of the W3C Blockchains and the Web workshop  held on 29-30 June, 2016, in Cambridge, Massachusetts, USA. Participants at the workshop found many topics for possible standardization or incubation, including various aspects of identity and proof-of-existence, as well as smaller blockchain primitives that could increase interoperability across different distributed ledgers. Discussion will continue in the Blockchain Community Group, which will coordinate across different communities and groups to foster standardization where needed, as discussed in the related blog post, “ Building Blocks of Blockchains “. This popular workshop had over one hundred attendees, and was hosted by MIT Media Lab and sponsored by NTT, Blockstream, and other W3C Members.
