How to work with Linked Data and RDF data in Javascript? Use JSON, the well known object notation. The W3C JSON for Linking Data Community Group published a bulk of new JSON-LD drafts and calls for final group specification commitments.

• JSON-LD Syntax 1.0: JSON-LD is designed as a lightweight syntax that can be used to express Linked Data. It is primarily intended to be a way to use Linked Data in Javascript and other Web-based programming environments.The syntax does not necessarily require applications to change their JSON, but allows one to easily add meaning by simply adding or referencing a context. (Call for Final Specification Commitments)
• JSON-LD API 1.0: JSON-LD may be used to express Linked Data in JSON. Often, it is useful to be able to transform JSON-LD documents so that they may be easily processed in a programming environment like JavaScript, Python or Ruby. Compaction, expansion and RDF conversion are discussed in this document. (http://www.w3.org/community/json-ld/2012/06/27/call-for-final-specification-commitments-for-json-ld-api-1-0/)
• JSON-LD Framing API 1.0: a JSON-LD document is a representation of a directed graph. A Frame can be used by a developer on a JSON-LD document to specify a deterministic layout for a graph. This document is a detailed specification for a serialization of Linked Data in JSON.
• RDF Graph Normalization: this document outlines an algorithm for generating a normalized RDF graph given an input RDF graph. Beside software developers the documents is primarily intended for masochists :)
