| |4. Call for Review: Pointer Events Level 2 is a W3C Proposed RecommendationПт., 09 нояб.[−]
The Pointer Events Working Group has published a Proposed Recommendation of Pointer Events Level 2. The features in this specification extend or modify those found in Pointer Events, a W3C Recommendation that describes events and related interfaces for handling hardware agnostic pointer input from devices including a mouse, pen, touchscreen, etc. For compatibility with existing mouse based content, this specification also describes a mapping to fire Mouse Events for other pointer device types.
Comments are welcome through 13 November 2018.

The W3C SVG Working Group has published an updated Candidate Recommendation of Scalable Vector Graphics (SVG) 2. This specification defines the features and syntax for Scalable Vector Graphics (SVG) Version 2. SVG is a language based on XML for describing two-dimensional vector and mixed vector/raster graphics. SVG content is stylable, scalable to different display resolutions, and can be viewed stand-alone, mixed with HTML content, or embedded using XML namespaces within other XML languages. SVG also supports dynamic changes; script can be used to create interactive documents, and animations can be performed using declarative animation features or by using script.
|↑|8. W3C Invites Implementations of CSS Containment and Flexible Box Layout Module Level 1Чт., 08 нояб.[−]
The CSS Working Group invites implementations of two updated Candidate Recommendations:
- CSS Containment Module Level 1 describes the ‘contain’ property, which indicates that the element’s subtree is independent of the rest of the page. This enables heavy optimizations by user agents when used well.
- CSS Flexible Box Layout Module Level 1 describes a CSS box model optimized for user interface design. In the flex layout model, the children of a flex container can be laid out in any direction, and can “flex” their sizes, either growing to fill unused space or shrinking to avoid overflowing the parent. Both horizontal and vertical alignment of the children can be easily manipulated. Nesting of these boxes (horizontal inside vertical, or vertical inside horizontal) can be used to build layouts in two dimensions.
CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, etc.

The Distributed Tracing Working Group has published a First Public Working Draft of Trace Context. A distributed application is an application that consists of multiple components, also known as micro-services, that are deployed and operated separately. The Trace Context specification defines properties intended for event correlation between micro-services to allow various tracing and diagnostics monitoring products to operate together.
|↑|13. Upcoming Workshop: Strong Authentication and IdentityВт., 06 нояб.[−]
W3C announced today a W3C Workshop on Strong Authentication and Identity, December 10-11 2018, in Redmond, WA, USA. The event is hosted by Microsoft.
This workshop will look to provide an existing standards landscape, roadmap and potential future work for how strong identity and strong authentication should work on the web. A successful workshop will be how to align recent W3C specifications (WebAuthn, Verifiable Claims, Web Payments) and work that is ongoing in the W3C Credentials Community Group (DID, DIDAuth) along with IETF and ISO, as well as other existing community standards such as Open ID Connect, Oauth, SAML, etc.
The scope includes:
- Strong Authentication: FIDO, WebAuthn, IFAA, DIDAuth, OpenID Connect
- Strong Identity: ISO 29003, Entity Attestation Token (EAT)
- Decentralized Identity (DID): Blockchain / Distributed Ledger Technologies, Verifiable Credentials
- Federation: OpenID Connect, SAML, DID
- Credentials: Verifiable Credentials, JWT, JSON-LD, Entity Attestation Token (EAT)
- Requirements: Ease of Use, Accessibility, Internationalization, Security, Privacy
For more information on the workshop, please see details and submission instructions. Expression of Interest and position statements are due by 29 October 2018.
|↑|17. Upcoming Workshop: Web Standardization for Graph DataПн., 15 окт.[−]
W3C announced today a Workshop on Web Standardization for Graph Data, 4-6 March 2019, in Berlin, Germany. The event is hosted by Neo4J.
This workshop brings together people with an interest in the future of standards relating to graph data, and its ever growing importance in relation to the Internet of Things, smart enterprises, smart cities, etc., open markets of services, and synergies with Artificial Intelligence and Machine Learning (AI/ML).
The scope includes:
Harmonising different perspectives on database management systems:
- The role of annotations, e.g. spatial, temporal, provenance, data quality, trust, etc. and opportunities for extending RDF to better support them;
- the relationship between RDF and other related approaches, e.g. Labelled Property Graphs and work by ETSI ISG CIM;
- requirements for graph query and update languages and
- requirements for rule languages for graph data.
Managing the silos, big data, AI and machine learning:
- Techniques for dealing with incomplete, uncertain and inconsistent knowledge;
- different kinds of reasoning, e.g. deductive, inductive, abductive, analogical, spatial, temporal, causal, social, and emotional and
- challenges for Big Data, AI/ML, and enterprise knowledge-graphs.
Scalability, security, trust, APIs and vocabulary development:
- Techniques for mapping data between vocabularies with overlapping semantics, as a basis for scaling across different communities;
- digital signatures for RDF and Property graphs, e.g. to verify that the graph hasn’t been tampered with;
- what’s next for remote access to data and information services;
- how to make W3C a more attractive venue for work on vocabularies.
We aim to share experiences, use case studies, new directions and insights on what’s needed for the next generation of Web data standards.
For more information on the workshop, please see details and submission instructions, and further background information. Expression of Interest and position statements are due by 15 December 2018.

|↑|21. Call for Review: Selectors Level 3 is a W3C Proposed RecommendationВт., 09 окт.[−]
The CSS Working Group has published a Proposed Recommendation of Selectors Level 3. Selectors are patterns that match against elements in a tree, and as such form one of several technologies that can be used to select nodes in an XML document. Selectors have been optimized for use with HTML and XML, and are designed to be usable in performance-critical code. This document describes the selectors that already exist in CSS1 [ CSS1] and CSS2 [ CSS21], and further introduces new selectors for CSS3 and other languages that may need them.
Comments are welcome through 12 October 2018.
|↑|22. First Public Working Drafts: JSON-LD 1.1 Syntax, JSON-LD 1.1 Processing Algorithms and API, and JSON-LD 1.1 FramingЧт., 27 сент.[−]
The W3C JSON-LD Working Group has published three First Public Working Drafts today.
The JSON-LD 1.1 Syntax document defines a JSON-based format to serialize Linked Data. The syntax is designed to easily integrate into deployed systems that already use JSON, and provides a smooth upgrade path from JSON to JSON-LD. It is primarily intended to be a way to use Linked Data in Web-based programming environments, to build interoperable Web services, and to store Linked Data in JSON-based storage engines. The 1.1 version of this specification will extend the existing JSON-LD 1.0 Recommendation, published in 2014.
The JSON-LD 1.1 Processing Algorithms and API document defines a set of algorithms for programmatic transformations of JSON-LD documents. Restructuring data according to the defined transformations often dramatically simplifies its usage. Furthermore, this document proposes an Application Programming Interface (API) for developers implementing the specified algorithms. The 1.1 version of this specification will extend the existing JSON-LD Processing Algorithms and API Recommendation, published in 2014.
The JSON-LD 1.1 Framing document defines an approach that allows developers to query by example and force a specific tree layout to a JSON-LD document.
All three documents are derived from Community Group Reports published by the JSON for Linking Data W3C Community Group.
The Working Group welcomes comments via the GitHub repository issues (see the respective documents’ headers for the reference of the repositories).
