The Web Applications Working Group has published a Working Draft of Selection API. This document is a preliminary draft of a specification for the Selection API and selection related functionality. It replaces a couple of old sections of the HTML specification, the selection part of the old DOM Range specification.

The RDF Data Shapes Working Group has published a Working Draft of Shapes Constraint Language (SHACL). SHACL (Shapes Constraint Language) is a language for describing and constraining the contents of RDF graphs. SHACL groups these descriptions and constraints into “shapes”, which specify conditions that apply at a given RDF node. Shapes provide a high-level vocabulary to identify predicates and their associated cardinalities, datatypes and other constraints. Additional constraints can be associated with shapes using SPARQL and similar extension languages. These extension languages can also be used to define new high-level vocabulary terms. SHACL shapes can be used to communicate information about data structures associated with some process or interface, generate or validate data, or drive user interfaces. This document defines the SHACL language and its underlying semantics.

The HTML Working Group has published a Proposed Recommendation of W3C DOM4. DOM defines a platform-neutral model for events and node trees. DOM4 adds Mutation Observers as a replacement for Mutation Events. Comments are welcome through 03 November.

The Web Applications Working Group has published a Working Draft of Shadow DOM. This specification describes a method of combining multiple DOM trees into one hierarchy and how these trees interact with each other within a document, thus enabling better composition of the DOM.
