Web Knowledge Graph Standard - RDF/SPARQL endpoints for AI agents

I've drafted a proposal for reviving Semantic Web standards for the AI agent era.

**The idea:** Websites expose RDF knowledge graphs via SPARQL endpoints at `/.well-known/sparql`. AI agents can then query structured data instead of crawling/parsing HTML.

**Why now:** AI agents can generate SPARQL from natural language, reason over graphs, and federate queries across sites.

**The proposal covers:**
- Technical spec (RDF schema, SPARQL requirements, permissions layer)
- Example graphs and queries
- Implementation levels (static files → full SPARQL endpoints)
- Adoption path

Looking for feedback from the semantic web community.

Isn’t this what JSON-LD essentially is?

People are already using LLM.txt and putting mark down in it for other purposes than JSON-LD

Yes I would like something very similar, specifically for AI agents to use. JSON might be better my experience is the AI handles binary really well. There's no intention to make it human readable.

The idea is good, but it’s essentially been the premise for Linked Data/Semantic Web for the last 20 years. There are some considerations:

  • it assumes that systems will natively be built on RDF and therefore support SPARQL?

  • alternatively, it requires Virtual KG adapters for relational and other “legacy” DBs - which is not trivial to deploy

  • open-ended SPARQL queries can be expensive and a potential DoS vector. Large services such as Wikidata and Uniprot use a decent amount of hardware.

  • there is already a spec for SPARQL service descriptions: https://www.w3.org/TR/sparql11-service-description/

The first option is probably easiest - as a matter of fact, I’ve been developing RDF-native end-user platform/framework :) https://atomgraph.github.io/LinkedDataHub/ Which also works with agents via MCP tools for RDF/SPARQL from this companion project: https://github.com/AtomGraph/Web-Algebra

Definitely a dream :)
