Revision as of 02:40, 19 December 2012

This is a transition request, and also serves as an agenda for a Transition Meeting with the Director.

See @@archived e-mail version.

__NUMBEREDHEADINGS__

1 Documents

We propose to publish the following three documents as Proposed Recommendation. These documents were advances to CR when the other SPARQL documents skipped to CR and advanced straight to PR, in October 2012.

For each document, in this section, we provide information in the following form:

 
     	(proposed status) for (title)
	(Latest TR Version URL)
	(Current Editor's draft URL)
	(URL of Resolution to Publish)

PR for "SPARQL 1.1 Entailment Regimes"
http://www.w3.org/TR/sparql11-entailment/
http://www.w3.org/2009/sparql/docs/entailment/
http://www.w3.org/2009/sparql/meeting/2012-12-11#resolution_6

	SPARQL is a query language and a protocol for data that is
	stored natively as RDF or viewed as RDF via middleware. The
	main mechanism for computing query results in SPARQL is
	subgraph matching: RDF triples in both the queried RDF data
	and the query pattern are interpreted as nodes and edges of
	directed graphs, and the resulting query graph is matched to
	the data graph using variables as wild cards. Various W3C
	standards, including RDF and OWL, provide semantic
	interpretations for RDF graphs that allow additional RDF
	statements to be inferred from explicitly given
	assertions. Many applications that rely on these semantics
	require a query language such as SPARQL, but in order to use
	SPARQL, basic graph pattern matching has to be defined using
	semantic entailment relations instead of explicitly given
	graph structures. There are different possible ways of
	defining a basic graph pattern matching extension for an
	entailment relation. This document specifies one such way for
	a range of standard semantic web entailment relations. Such
	extensions of the SPARQL semantics are called entailment
	regimes within this document. An entailment regime defines not
	only which entailment relation is used, but also which queries
	and graphs are well-formed for the regime, how the entailment
	is used (since there are potentially different meaningful ways
	to use the same entailment relation), and what kinds of errors
	can arise. The entailment relations used in this document are
	standard entailment relations in the semantic web: RDF
	entailment, RDFS entailment, D-entailment, OWL Direct and
	RDF-Based Semantics entailment, and RIF Core entailment.


PR for "SPARQL 1.1 Protocol"
http://www.w3.org/TR/sparql11-protocol/
http://www.w3.org/2009/sparql/docs/protocol-1.1/
http://www.w3.org/2009/sparql/meeting/2012-12-11#resolution_5
	
	The SPARQL Protocol and RDF Query Language (SPARQL) is a query
	language and protocol for RDF. This document specifies the
	SPARQL Protocol; it describes a means for conveying SPARQL
	queries and updates to a SPARQL processing service and
	returning the results via HTTP to the entity that requested
	them. This protocol was developed by the W3C SPARQL Working
	Group, part of the Semantic Web Activity as described in the
	activity statement .


PR for "SPARQL 1.1 Graph Store HTTP Protocol"
http://www.w3.org/TR/sparql11-http-rdf-update/
http://www.w3.org/2009/sparql/docs/http-rdf-update/
http://www.w3.org/2009/sparql/meeting/2012-12-11#resolution_7

	This document describes the use of HTTP operations for the
	purpose of managing a collection of RDF graphs. This interface
	is an alternative to the SPARQL 1.1 Update protocol. Most of
	the operations defined here can be performed using that
	interface, but for some clients or servers, this interface may
	be easier to implement or work with. This specification may
	serve as a non-normative suggestion for HTTP operations on RDF
	graphs which are managed outside of a SPARQL 1.1 graph store.

2 Status Sections, Changes since Last Call

Before publication, the status sections for all the documents will changed to be the standard boilerplate for the given status level, plus text about the changes since the last publication. Query also includes a brief statement of what's new in SPARQL 1.1. Specifically:

Entailment Regimes - removed "at risk" notices

Protocol - Fixed typo when referencing the application/x-www-form-urlencoded media type.

Graph Store HTTP Protocol - no changes


3 Satisfies Group's Requirements

The requirements have not changed since the previous transition. None of the many reviews have claimed that the documents fail to satisfy the group's requirements.

The charter deliverables are met by the group's publications, along with the test suite website.

4 Dependencies

No changes since last Transition, in which no dependency problems were identified.

5 Issues Formally Addressed

See:

6 Objections

There have been no formal objections.

7 Implementations

The group maintains a table of implementations and test results (snapshot 18 December 2012).

The group approved the exit criteria of have each approved test passed by two or more implementations.

8 Patent Disclosures

None.
