    SPARQL 1.1: Proposed Recommendation

    El grupo W3C SPARQL Working Group ha publicado SPARQL 1.1 como Proposed Recommendation. Tras el exito de SPARQL 1.0, SPARQL 1.1 es un estándar complete para trabajar con datos RDF que incluye lenguaje de consulta y actualización, dos protocolos HTTP, resultados en tres formatos, y otras características explotandos los puntos SPARQL. La mayoría de las características de SPARQL 1.1 han sido ya implementadas por varios proveedores como muestra la siguiente tabla.

    The Proposed Recommendations are:

    1. SPARQL 1.1 Overview - Overview of SPARQL 1.1 and the SPARQL 1.1 documents
    2. SPARQL 1.1 Query Language - A query language for RDF data.
    3. SPARQL 1.1 Update - Specifies additions to the query language to allow clients to update stored data
    4. SPARQL 1.1 Query Results JSON Format - How to use JSON for SPARQL query results
    5. SPARQL 1.1 Query Results CSV and TSV Formats - How to use comma-separated values (CVS) and tab-separated values (TSV) for SPARQL query results
    6. SPARQL Query Results XML Format - How to use XML for SPARQL query results. (This contains only minor, editorial updates from SPARQL 1.0, and is actually a Proposed Edited Recommendation.)
    7. SPARQL 1.1 Federated Query - an extension of the SPARQL 1.1 Query Language for executing queries distributed over different SPARQL endpoints.
    8. SPARQL 1.1 Service Description - a method for discovering and a vocabulary for describing SPARQL services.

    The following are Candidate Recommendations, as the group still seeks more feedback from implementors:

    1. SPARQL 1.1 Entailment Regimes - defines the semantics of SPARQL queries under entailment regimes such as RDF Schema, OWL, or RIF.
    2. SPARQL 1.1 Protocol for RDF - A protocol defining means for conveying arbitrary SPARQL queries and update requests to a SPARQL service.
    3. SPARQL 1.1 Graph Store HTTP Protocol - As opposed to the full SPARQL protocol, this specification defines minimal means for managing RDF graph content directly via common HTTP operations.

    The group has also produced a test suite and a page on using SPARQL 1.1 with RDF 1.1.
