Proposed Group: SPARQL Maintenance (EXISTS) Community Group

The SPARQL Maintenance (EXISTS) Community Group has been proposed by Andy Seaborne:

The “SPARQL Maintenance (EXISTS)” Community Group is a forum to discuss and address problems with the “EXISTS” feature in SPARQL 1.1.

The SPARQL 1.1 suite of specifications and the SPARQL 1.1 test suite are frozen. A process exists to record errata and that will be one input to any working group chartered to revise SPARQL.

In the meantime, SPARQL is being used in real-work systems in industry and public-sector. The user community expects a high degree of conformance across implementations.

The EXISTS feature has been found to be problematic. This feature is used by the RDF Data Shapes Working Group.

This community group will create CG Notes and accompanying test suites to describe one or more improvements with an emphasis on maintaining compatibility.

This group is not producing specifications.

Any tests produced by the will submitted to the RDF Test Suite Curation CG for long-term stewardship.

You are invited to support the creation of this group. Once the group has a total of five supporters, it will be launched and people can join to begin work. In order to support the group, you will need a W3C account.

Once launched, the group will no longer be listed as “proposed”; it will be in the list of current groups.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please send us email on site-comments@w3.org

Thank you,
W3C Community Development Team
