The DataCite Technology Stack

DataCite is a DOI registration agency that enables the registration of scholarly content with a persistent identifier (DOI) and metadata. This content can then be searched for, reused, and connected to other scholarly resources. But how does the underlying infrastructure enable this? In this blog post, we will describe what we have built to make […]

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 […]
