RDF Triplestore plugin for claims data

[jimschoening1]

I co-chair DIF Credential Schemas Work Item.

Kim Hamilton Duffy suggested we use Veramo for our reference implementation, but does Veramo have an RDF triplestore? If not, could an opensource version such as GraphDB be proposed? If so, is anyone interested in helping or guiding us?

Background: Our draft standard schema includes PURLs to standard ontology classes (for rich and scalable standard semantics), which enables a verifier app to automatically understand the VC claim data, plus allows external vendors to map to the standard ontologies, plus enables individuals to collect claims data that can be combined/integrated for added value. One version of our draft schema is called PDM Glossary. We're working in collaboration with IEEE Ontology Standards Working Group, which I also chair. My team started a similar effort as a Linux project in 2022 at https://github.com/integrated-personal-data-system.
