I’m co-creating a knowledge graph for the the Regeneration / Impact ecosystem. We are talking to some projects that are using Ceramic to store profiles for users, for ex Gitcoin Passport which stores a JSON blob of Verifiable credentials on Ceramic. In addition to people and project profiles, we want to support any other related data that will ideally be standardized by a schema.
I see you are working on knowledge graph functionality with composeDB, which is a SQL db with GraphQL for queries. Could this allow complex SPARQL-like queries across all data on Ceramic? We are still deciding on what database architecture to use and are considering a semantic graph db based on RDF & SPARQL. Would it work for us to store everything on Ceramic?
Sorry to hijack this thread months later, but I was sent this way when I asked about RDF in the Discord, and came across this thread. I also follow the Fluree project which implements a RDF graph engine atop a blockchain state layer. Really interesting project. They’re in the midst of finalizing their JSON-LD support now.
They support SPARQL (along with their own QL), but also GraphQL; the GraphQL endpoint is just more limited in the nature of the queries you can express.
Anyway, originally I was wondering if Ceramic can support RDF style triples? It would be powerful to be able to speak JSON-LD and leverage vocabularies from i.e. schema.org when defining ComposeDB schema.
