The W3C working group is tasked with developing the next-generation RDF and SPARQL recommendations. With significant progress already made, the latest developments will be shared directly by the group’s participants.

The Lotico community is excited to host a presentation on the future of RDF. We'll begin by exploring the new reification scheme in RDF 1.2, which introduces triples as a new object type, alongside IRIs, blank nodes, and literals. This enhancement improves the reification mechanism, enabling "linking to links."

We will also discuss how these advancements enable the annotation of asserted triples, allowing the addition of “marginalia” for fact provenance and context through "reifiers." Both Turtle and SPARQL will support this new syntax, and JSON-LD 1.2 is expected to follow suit.

Additionally, we will examine how reifiers interact with named graphs and review the introduction of an optional text direction for language literals. In the RDF 1.2 Semantics draft, triples are used to represent propositions—core units of meaning in propositional logic.

Speakers:

Niklas Lindström is the Co-Chair of the DCMI Usage Board and has a background in consulting for web and data technologies. He was part of the W3C RDFa 1.1 working group and co-authored JSON-LD 1.0. Currently a systems developer at the National Library of Sweden, Niklas specializes in linked data structures, semantics, protocols, and interoperability. The Usage Board oversees the maintenance of all DCMI vocabularies, including DCMI Metadata Terms and ISO 15836.

Andy Seaborne champions open software development and serves as Vice President at Apache Software Foundation, representing W3C Relations. He is the chair and a contributor to the Apache Jena project, a free and open-source Java framework for building Semantic Web and Linked Data applications.
