Approaches to Publishing Linked Data via Named Graphs [Lost Boy]
to look at how Named Graphs can be used to support publishing of Linked Data. There are two scenarios... The first uses Named Graphs in a way that provides a low friction method for publishing Linked Data. The second prioritizes ease of data management, and in particular the scenario where RDF is being generated by converting from other sources - by Leigh Dodds, 2009-12-20 (original post at 00:25)

@danbri, if we want to find 'topics', then rel would be foaf:topic. Or if just 'entities', not sure worth describing as global RDF graph... (original post at 19:06)
linked-data-api [Project Hosting on Google Code]
For some web developers the need to understand the RDF data model and associated serializations and query language (SPARQL) has proved a barrier to adoption of linked data. This project seeks to develop APIs, data formats and supporting tools to overcome this barrier. Including, but not limited to, accessing linked data via a developer-friendly JSON format - by Dave Reynolds and Jeni Tennison (original post at 00:29)

Host-meta (aka Site-meta) and Well-Known URIs [hueniverse]
Instead of creating a well-known location document, the proposal creates a directory under which future well-known location documents should reside... there is a need for a metadata document about a host... Another new feature of the host-meta proposal is the use of XRD as the document schema - by Eran Hammer-Lahav, 2009-11-23 (original post at 00:12)

Towards Formal HTTP Semantics [AWWSW Report to the TAG]
Discussions of Web architecture and the semantics of communication on the Web get mired in confusion over definitions and how different conceptual models of Web resources compare... We are speaking here not about the details Web protocols, but about what these protocols say about resources "identified" by URIs, and how what is transmitted relates to these resources - by Jonathan Rees et al., 2009-12-14 (original post at 12:13)
