The Web Annotation Working Group has just published a Recommendation for Web Annotation in the form of three documents:
- Web Annotation Data Model—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—describes the transport mechanisms for creating and managing annotations in a method that is consistent with the Web Architecture and REST best practices.
The group has also produced two additional Working Group Notes:
- Embedding Web Annotations in HTML—describes and illustrates potential approaches for including annotations within HTML documents. Examples also are included illustrating the use within an HTML document of annotation Selectors as fragment identifiers.
- Selectors and States—selecting part of a resource on the Web is an ubiquitous action. This document does not define any new approach to selection; instead, it relies on the formal specification and the semantics in the Web Annotation Data Model. The current document only “extracts” Selectors and States from that data model; by doing so, it makes their usage easier for applications developers whose concerns are not related to annotations.

To further the growth of market for IoT devices and services, W3C has launched the Web of Things Working Group to develop initial standards for the Web of Things, tasked with the goal to counter the fragmentation of the IoT; reduce the costs of development; lessen the risks to both investors and customers; and encourage exponential growth in the market for IoT devices and services.
In advance of W3C’s presence at Mobile World Congress 2017 next week, where W3C executives will be available on 27-29 February, W3C CEO Dr. Jeff Jaffe commented, “There are huge, transformative opportunities not only for mobile operators but for all businesses if we can overcome the fragmentation of the IoT. As stewards of the Open Web Platform, W3C is in a unique position to create the royalty-free and platform-independent standards needed to achieve this goal.“

The CSS Working Group has published two First Public Working Drafts today:
- CSS Timing Functions Level 1, a module that describes a way for authors to define a transformation to be applied to the time of an animation. This can be used to produce animations that mimic physical phenomena such as momentum or to cause the animation to move in discrete steps producing robot-like movement.
- CSS Containment Module Level 1, a module which 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.
