DAIS-WG Status Update at OGF23: Progress on Data Access and Integration Services

The Database Access and Integration Services Working Group (DAIS-WG) provides updates on its specifications and implementations as of OGF23. Key documents include the WS-DAI and WS-DAIR specifications and the ongoing RDF/RDFS realizations. Implementations by institutions such as Ohio State University and AMGA are highlighted, along with plans for collaboration with SAGA. Important resources, including motivational documents and glossaries, support the group's efforts in enhancing interoperability in data access and integration.
