Today DataCite is proud to announce the launch of DataCite Commons, available at https://commons.datacite.org. DataCite Commons is a discovery service that enables simple searches while giving users a comprehensive overview of connections between entities in the research landscape.
We are pleased to announce the launch of the new persistent identifier (PID) services registry available at https://pidservices.org, a new service to find services built upon different PIDs from core technology providers and those who integrate from across a variety of disciplinary areas.
Today DataCite launches a new API that powers the PID Graph, the graph formed by scholarly resources described by persistent identifiers (PIDs) and the connections between them. The API is powered by GraphQL, a widely adopted Open Source technology that enables queries of this graph, addressing use cases of our community in ways that were not possible before.
The connections between scholarly resources generated by persistent identifiers (PIDs) and associated metadata form a graph: the PID Graph [@https://doi.org/10.5438/jwvf-8a66]. We developed this PID Graph concept in the EC-funded FREYA project, and have identified important use cases and technical requirements.
Two weeks ago DataCite announced the pre-release version of a GraphQL API [@https://doi.org/10.5438/qab1-n315]. GraphQL simplifies complex queries that for example want to retrieve information about the authors, funding and data citations for a dataset with a DataCite DOI.
DataCite DOIs describe resources such as datasets, samples, software and publications with rich metadata.
DOI metadata provenance is describing the history of a particular DOI metadata record, i.e. what changes were made when and by whom. This information is now stored and provided via an API for all DOI registrations since March 10, 2019. The following provenance information is now available via a new /activities REST API endpoint: prov:wasGeneratedBy . The unique identifier for the activity making changes to a DOI record.
This post has been cross-posted from the FREYA blog. Persistent identifiers (PIDs) are not only important to uniquely identify a publication, dataset, or person, but the metadata for these persistent identifiers can provide unambiguous linking between persistent identifiers of the same type, e.g. journal articles citing other journal articles, or of different types, e.g. linking a researcher and the datasets they produced.
