The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

By unifying research software with its scholarly context in a single graph, SemRepo provides an important infrastructure for large-scale analysis of software within the broader scientific research ecosystem.

C2weakest assumption

The interlinks between GitHub repositories, SemOpenAlex author profiles, LPWC publications, and MLSea-KG artifacts are sufficiently accurate and complete to support reliable provenance reconstruction and systematic identification of reproducibility risks.

C3one line summary

SemRepo is a new RDF knowledge graph integrating GitHub research repositories with scholarly knowledge graphs to enable cross-platform queries on software, publications, and artifacts.
