W3C Workshop Report: Blockchains and the Web

26 August 2016 | Archive

Blockchain workshop graphical representationW3C published today 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.

Sensors on the Web: APIs Under Wide Review

30 August 2016 | Archive

The Device and Sensors Working Group has published a Working Draft of the Generic Sensor API, a framework to bring support for any kind of sensors to the Open Web Platform. An updated Working Draft of the Ambient Light API illustrates a concrete sensor API based on this framework.

The Working Group has determined that these APIs are now advanced enough that they would benefit from getting wide review from the broader community and welcome feedback from implementors and developers on both these documents.

First Public Working Draft: Input Events

30 August 2016 | Archive

The Web Platform Working Group has published a Working Draft of Input Events. This specification defines additions to events for text and related input to allow for the monitoring and manipulation of default browser behavior in the context of text editor applications and other applications that deal with text input and text formatting. It builds on the UI events spec.

Call for Review: Pointer Lock Proposed Recommendation Published

30 August 2016 | Archive

The Web Platform Working Group has published a Proposed Recommendation of Pointer Lock. This specification defines an API that provides scripted access to raw mouse movement data while locking the target of mouse events to a single element and removing the cursor from view. This is an essential input mode for certain classes of applications, especially first person perspective 3D applications and 3D modeling software. Comments are welcome through 30 September.

W3C Invites Implementations of its Data on the Web Best Practices

30 August 2016 | Archive

The Data on the Web Best Practices Working Group has published its primary document which is now a Candidate Recommendation. The document provides Best Practices related to the publication and usage of data on the Web designed to help support a self-sustaining ecosystem. Data should be discoverable and understandable by humans and machines. Where data is used in some way, whether by the originator of the data or by an external party, such usage should also be discoverable and the efforts of the data publisher recognized. In short, following these Best Practices will facilitate interaction between publishers and consumers.

As a further aid, the Working Group has also published stable versions of its Data Quality and Dataset Usage vocabularies. Taken together, the three documents address the group’s mission as stated in its charter:

  1. to develop the open data ecosystem, facilitating better communication between developers and publishers;
  2. to provide guidance to publishers that will improve consistency in the way data is managed, thus promoting the re-use of data;
  3. to foster trust in the data among developers, whatever technology they choose to use, increasing the potential for genuine innovation.

Finally, it’s worth noting that the closely related Share-PSI project, co-funded by the European Commission, has concluded its work recently with the publication of a set of high level policy-related Best Practices and guides for the sharing of public sector information online. Although targeted at Europe, the advice, which is available in many languages and contexts, is likely to be applicable world wide.

First Public Working Draft: SHACL Core Abstract Syntax and Semantics

26 August 2016 | Archive

The RDF Data Shapes Web Working Group has published a Working Draft of SHACL Core Abstract Syntax and Semantics. This document defines an abstract syntax for the core SHACL (SHApes Constraint Language). It is derived from the SHACL specification and is a non-normative version of the content of that specification.
