#virtuosordbms — Public Fediverse posts

Tools used:

1. Anthropic’s Claude Code as the AI agent

2. DeepSeek-v4 as the LLM

3. Virtuoso Data Spaces platform, comprising:

* A WebDAV-based filesystem for hosting generated RDF, HTML, and Markdown documents
* A high-performance DBMS engine that automatically ingests and manages these documents
* Support for RDF graphs and relational tables accessible via SQL, SPARQL, GraphQL, etc. (note: we also have openCypher and GQL in the works to bury all distractions)

What’s going on here?

Prompts are being processed through queries executed against a Knowledge Graph (KG)—all thanks to loose coupling. The target KG could reside locally, live on the Web, or be part of the vast Linked Open Data (LOD) cloud.

Architecture? As depicted in the attached image.

BTW -- @Google Gemini can generate pretty accurate diagrams using @drawio XML!

A simple GUI-based screencast demo of the @openlink AI Layer (OPAL), showing what’s now possible via MCP + A2A—namely, composing and orchestrating agentic workflows through loosely coupled software.

How?

An Agent Host routes tasks to Agents via A2A. Agents then invoke MCP-accessible tools (functions, procedures, APIs) described using JSON/YAML and exposed via OpenAPI.

Just another example of the Semantic Web vision in action—modernized for the AI era. 😀

Here’s a DataTwingler AI Agent configuration in Markdown, designed for interacting with UniProt’s massive Knowledge Graph, which consists of 210 billion machine-computable statements of fact, meticulously curated by domain experts.

https://github.com/OpenLinkSoftware/Assistants/blob/main/data-twingler-uniprot.md

This AI Agent enables scalable, explainable, and verifiable AI interactions with UniProt’s Knowledge Graph, seamlessly integrating LLMs with high-quality biomedical data via its #VirtuosoRDBMS-based SPARQL query services endpoint.

UniProt’s latest publicly accessible Knowledge Graph now contains 210,122,358,019 RDF triples—powered by our (@openlink) #VirtuosoRDBMS open-source edition, live on the Web and available to AI Agents, Applications and Services across life sciences, genomics, bioinformatics, molecular biology, and related fields.

Utility?

210,122,358,019 factual statements, curated by domain experts, in subject, predicate, and object sentence form—all accessible via a live SPARQL Query Service endpoint.

Boom! The OpenLink Software AI Layer (#OPAL) now supports Anthropic's #Claude language models. See comments for a #DataTwingler #AI Agent demo executing #SPARQL and #SQL queries via a live #VirtuosoRDBMS instance. Screencast Demo: www.openlinksw.com/data/screenc...

Q: Can recent #GenAI innovations really optimize Customer Support?

A: Absolutely! With #Firefox’s recent #LLM integration, I can even demonstrate this benefit via split-screen using our #VirtuosoRDBMS support assistant and #CustomGPT.
