Journal title, ISSN, publisher, and homepage are checked against open metadata where available.
Catalog transparency
Data Sources
Frame separates journal identity, scope, indexing, fees, metrics, and trust signals so users can see what is source-backed and what still needs verification.
Open metadataSource claimsVerification status
DOAJ, PubMed, TR Dizin, and similar claims are marked verified only when a source supports them.
APC, metrics, and review timing can remain not verified instead of being treated as confirmed facts.
Primary source types
Frame uses open catalog and publisher-side signals such as Crossref, OpenAlex, DOAJ, PubMed/NLM, TR Dizin, publisher pages, and stored source-claim records.
Verified sources
WoS, Scopus, JCR, and similar claims are treated as verified only when a reliable public, official, manual, or curated source supports the claim.
How this affects routes
A journal can be a good fit while still showing verification needs. Missing APC or metric data should not erase fit, but it should remain visible before submission.
