{"identifier":"0000044","name":"PID4NFDI Providers","description":"[PID4NFDI](https://pid.services.base4nfdi.de) is a Base4NFDI service that provides documentation about a small number of well-known identifier schemes (e.g., DOI) and services for registering identifiers within them (e.g., DataCite). This collection reflects their [PID Providers](https://pid.services.base4nfdi.de/get-pid/providers/) page. This comes with the following caveats:\n\n- Crossref and DataCite are services that mint DOIs. Since DOIs are the identifier space, only `doi` appears in this collection.\n- ePIC is a service that mints Handle system. Since Handles are the identifier space, only `hdl` appears in this collection\n- PIDINST is an abstraction on top of DataCite / ePIC, which is covered by `doi` and `hdl` as described above","resources":["ark","doi","factgrid","gnd","hdl","igsn","orcid","pida","raid","ror","swh","wikidata"],"contributors":[{"name":"Charles Tapley Hoyt","orcid":"0000-0003-4423-4370","email":"cthoyt@gmail.com","github":"cthoyt"}]}
