DataCite Commons at your service

DataCite and the FREYA project partners are proud to announce the official launch of DataCite Commons today. DataCite Commons is the web interface to explore the PID Graph, formed by the publications, datasets, research software, and other research outputs generated by researchers working at research institutions and supported by grant funding [@ttps://doi.org/10.5438/jwvf-8a66]. The PID Graph […]

Tracking the Growth of the PID Graph

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. In May, DataCite introduced a GraphQL API to standardize and simplify how users can contribute […]

Using Jupyter Notebooks with GraphQL and the PID Graph

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. These connections together form the PID Graph [@https://doi.org/10.5438/jwvf-8a66], and DataCite is working with the other partners in […]

Introducing the PID Graph

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 […]
