il DOI “doi:10.1042/0264-6021” associato a br/06403991825 non esiste tra i Crossref Works, ma risolve portando alla pagina del journal con “doi.org/”.

Altri casi di OMID con più DOIs associati: vedi lista di multi-mapped e controlla dopo che sia ancora così sull’API

https://opencitations.net/meta/api/v1/metadata/omid:br/06403991825 → 1643 DOIs, tutti di articoli dallo stesso journal
https://doi.org/10.1042/0264-6021 → il DOI risolve sulla home del journal, ma è assente in Crossref (almeno tra i Works accessibili via API: https://api.crossref.org/works/10.1042/0264-6021)
https://doi.org/ra/10.1042/0264-6021 → il DOI è registrato da Crossref

aspetta che Arca faccia una copia dell’RDF di v6 e te ne faccia avere una copia, poi rimanda sia i controlli sulla provenance, sia i controlli sui dati (sempre in RDF). Poi pubblica i due issue su GitHub usando i risultati dei controlli su entrambe le versioni (v5 e v6). Considera che il count delle BR nell’RDF ci mette un botto (tipo 24 ore!!)
chiedi a Ivan di scaricare l’ultimo snapshot di OpenAlex sul server, secondo la procedura dell’altra volta. Poi quando (presto) Arca genera il CSV dell’ultima versione di Meta (deve interrompere il processo di merge) manda subito il processo di mapping!

Provenance data: BRs missing primary source and BRs with more than one primary source for a single snapshot

In version 5 of “OpenCitations Meta RDF dataset of all bibliographic metadata and its provenance information” (https://doi.org/10.6084/m9.figshare.21747536.v5), there are 105,944,601 provenance graph objects for bibliographic resources, therefore the number of provenance graphs does not match the number of bibliographic resources in the triplestore (105,953,699, from what can be read in the dump’s metadata information on its Figshare page).

Additionally, a very small number (5) of bibliographic resource entities in the provenance RDF files are missing the primary source (the [<http://www.w3.org/ns/prov#hadPrimarySource>](<http://www.w3.org/ns/prov#hadPrimarySource>) property.

E.g.:

In the same dataset, moreover, the provenance graphs of 91,284 bibliographic resources have more than one primary source specified inside a single snapshot (while we would expect to have a distinct snapshot for each primary source).
