I2idl Linked Data MCP Server

I2IDL Linked Data

Open, interoperable Linked Data publication and research services for the I2IDL Glossary of Digital Learning. The project combines a curated semantic reference graph with browser-based exploration and experimental scholarly discovery.

Versioning: I2IDL uses one public release sequence (v0.0.88, v0.0.89, …). Each release is classified Content, Platform, or Combined. The public release tag, gs:publicationVersion, and Squarespace displayed version are synchronized for each release, while concept revisions change only when concept-level assertions change. The npm package and MCP registry versions remain separate compatibility identifiers. See the release policy and release checklist.

Public resources

What the project provides

• Curation and provenance: Persistent identifiers, definitions, evidence records, editorial collections, citations, rights and source attribution.
• Semantic interoperability: JSON-LD, SKOS, Dublin Core Terms, Schema.org, PROV-O, controlled relationships and selected external mappings.
• Graph exploration: Search and navigate a one- or two-hop concept network, shortest paths, comparison tools, field and source analytics.
• Scholarly discovery: Single-concept and two-to-five-concept OpenAlex searches with publication year, open-access, and citation ranking controls. Results remain uncurated discovery candidates, separate from I2IDL's assertions.
• Research export: CSV and BibTeX downloads of displayed publications with DOI and selected concept identifiers.
• Public aggregate activity: Daily pageviews, concept selections, successful research searches, and returned publication counts. These are not unique visitors or unique papers.
• Machine access: Persistent identifiers, JSON-LD and Turtle, read-only REST API v1, bounded SPARQL, and four read-only MCP tools for compatible AI clients.

Editorial boundary and licenses

Interactive analytics and OpenAlex search results do not write new statements into the canonical JSON-LD graph. New definitions, evidence, mappings and relationships require separate editorial review and validation.
