1 Linked Data Platform Working Group

Mission: produce a W3C Recommendation for HTTP-based (RESTful) application integration patterns using read/write Linked Data. (See Charter)

1.1 Status

The WG has been officially approved by the W3C and the call for participation marked the official launch of the WG. The WG is now active and has weekly calls. The First Public Working Draft is out for review. See below for additional info.

1.2 Deliverables

1.3 LDP Workshop

The Linked Data Platform WG is pleased to announce a special open meeting in San Francisco on April 21 hosted jointly with the Annotations WG which has meetings on the following days. See iAnnotate and Annotations WG f2f Anyone with an interest in Linked Data is urged to attend. This is important.

Please indicate below whether you will be able to attend the workshop.

  • GOALS:

The purpose of this meeting is to discuss potential future work for the WG. The deliverable from the workshop will be a report that the LDP WG will take into consideration as it plans its way forward.

The LDP spec has just been published as a W3C Recommendation. The Paging spec and the LDP Patch spec are Candidate Recommendations. The WG has other, non-essential, deliverables in various stages of completion. See WG Deliverables for details.

Clearly, the Paging spec and the Patch spec need to be completed and moved to Rec. But a more important question is what else needs to be done to advance Linked Data as a central Web technology.

  • FORMAT

Short, say, 15 minute presentations followed by open discussion. Please send presentation proposals to Public LDP Mailing List by April 1, 2015.

1.8 Linked Data Platform (LDP) vs SPARQL Graph Store HTTP Protocol (GSP)

From the start GSP was identified as a specification LDP overlaps with. The Working Group therefore had a look at how GSP and the Linked Data Basic Profile submission compare and discussed what ought to be done.

The WG concluded that the two specifications aren't very different but because they have different goals they cannot be fully reconciled. As of September 2012, LDP was merely an Editor's draft while GSP was in Last Call with a WG ready to disband so, there was basically no way GSP could be modified in any significant way to align with LDP. If any alignment was possible it ought be done on the LDP side.

Based on this, the LDP WG decided on its September 17th, 2012 call that it will seek to align LDP to GSP as much as possible.

See email thread and minutes for further details.

Subsequently, on behalf of the WG, Miel Vander Sande conducted a thorough review of how the two specifications compare. The results were captured in the document: Linked Data Platform (LDP) vs SPARQL Graph Store HTTP Protocol (GSP)
