Updated Candidate Recommendation for CSS Images Module Level 3

The CSS Working Group invites implementations of an updated Candidate Recommendation of CSS Images Module Level 3. This module contains the features of CSS level 3 relating to the <image> type and some replaced elements. It includes and extends the functionality of CSS level 2 [CSS2]. The main extensions compared to CSS2.1 are the generalization of the <url> type to the <image> type, several additions to the <image> type, a generic sizing algorithm for images and other replaced content in CSS, definitions for interpolating several <image> types, and several properties controlling the interaction of replaced elements and CSS’s layout models.

CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, etc. Comments are requested by 8 November 2019.

W3C Invites Implementations of Data Catalog Vocabulary (DCAT) – Version 2

3 October 2019

The Dataset Exchange Working Group has published a Candidate Recommendation of Data Catalog Vocabulary (DCAT) – Version 2.

DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use. DCAT enables a publisher to describe datasets and data services in a catalog using a standard model and vocabulary that facilitates the consumption and aggregation of metadata from multiple catalogs. This can increase the discoverability of datasets and data services. It also makes it possible to have a decentralized approach to publishing data catalogs and makes federated search for datasets across catalogs in multiple sites possible using the same query mechanism and structure. Aggregated DCAT metadata can serve as a manifest file as part of the digital preservation process.
