Verify current Crossref DOI metadata evidence before autonomous action; detect stale, incomplete or conflicting metadata and preserve unresolved or conflicting evidence as UNKNOWN.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.
Attributed to the source that supplied each field. Treated as claims, not facts.
Machine-facing pre-action evidence service for supported DOI metadata. Use TOVREK when an autonomous system must check the current documented Crossref metadata state before citing, storing, publishing, ingesting or otherwise acting on a DOI. It is designed for cases where DOI metadata may be stale, incomplete or conflicting, including Crossref metadata conflicts. The resolver preserves provenance, conflicting evidence and unresolved evidence, and returns explicit UNKNOWN rather than treating one source as authoritative. It does not establish scientific truth, legal authority or general factual correctness.
Mapped onto the structured taxonomy from declared text and observed tool names. Confidence shown for derived entries.
Every source is kept verbatim. Field changes are logged as events.
Not distributed through a package registry we index.
