I think the RDF standards have produced many useful tools for those that work with graph data. And the W3C is a useful coordination place for new standards like Verifiable Credentials[0] and Decentralized identifiers[1] and JSON Linked Data[2], which are all being used in ActivityPub, Bluesky, and a lot of other decentralizing projects.
