[alexgduarte]

/claim #17

Summary

Adds a dependency-free scientific-knowledge-graph/ MVP module for SCIBASE scientific knowledge graph integration.

Implemented coverage:

• Research object ingestion for papers, datasets, notebooks, and protocols.
• Deterministic extraction for concepts, gene-like symbols, tools, datasets, protocols, references, and DOIs.
• Author, affiliation, project, dataset, protocol, tool, concept, DOI, and research-object node types.
• Evidence-backed relationships for authored, affiliated-with, cites, mentions, uses, reuses, and co-occurs-with.
• Entity pages with citation contexts, related nodes, relationship evidence, and schema.org JSON-LD.
• Graph search and navigation payloads with domain, node-type, relationship-type, evidence, and text filters.
• Influence-path traversal between graph entities.
• Recommendation digest payloads for workspace sidebars or weekly emails.

Validation

cd scientific-knowledge-graph
npm test
npm run demo
git diff --check

All commands pass locally.

Notes

• No external packages or services are required.

Hi maintainers, quick check-in on this PR. It has been open for a week and is still clean with no review comments from what I can see. Is this module useful as submitted, or would you prefer any scope changes before consideration? Happy to adjust if needed.

Hi maintainers, quick follow-up on this module PR and the related SCIBASE module submissions. They are still open and mergeable from my side, but I have not seen maintainer direction yet. Is this MVP-module style useful for the project, or would you prefer a smaller scope / different integration shape before review? Happy to revise or close/rescope if needed.
