The OpenAIRE Broker service enables repository managers to enrich research artifacts with additional metadata. Through this service, a content provider manager will find additional and missing metadata for their collection, such as PIDs, links to projects, ORCIDs, additional classification subjects, among others. The service is being continuously developed to offer additional metadata enrichments and to improve their performance. This article presents the new approach to deliver the metadata enrichments for content provider managers, which will offer a preview of a set of enrichments and allow the subscription for notifications about new metadata enrichments of their interest.
OpenAIRE Broker Service
The Broker Service is available to use via the OpenAIRE Content Provider Dashboard. Thanks to the Broker, repositories, publishers or aggregators can exchange metadata and enrich their local metadata collection by subscribing to notifications of different types. The Broker is able to notify providers when the OpenAIRE Graph contains information that is not available in the original collection of the data source.
In particular, the data source manager can subscribe via the Content Provider Dashboard and be notified about:
- Additional PIDs of its publications (e.g. DOIs)
- Links to projects
- ORCID that can be associated to an author of datasource publications
- Links to Open Access versions
- Additional classification subjects (e.g. subjects from standard schemes like ACM, JEL and DDC)
- Links to datasets
- Missing publication dates
Novelties on how to subscribe metadata enrichments
All Repository managers approaching the Content Provider Dashboard will be offered the possibility to preview a set of enrichments relative to their repository that OpenAIRE can derive from the Graph. More specifically, enrichments will be organized into categories named topics and representing the different types of enrichments OpenAIRE can build.
For each topic the preview consists of 100 “enrichment events”, a subset of all the possible enrichments pertinent to a given repository in the OpenAIRE Graph, that the user can explore by applying filters on different criteria and the total number of events that can be potentially built is highlighted in the UI.
Repository managers can create subscriptions for specific topics and that include the filtering criteria they used to analyze the enrichments preview, or can subscribe to all the available topics with no restrictions at once.

Once the repository manager creates a subscription, the algorithm analyzing the OpenAIRE Graph will produce the full set of enrichments for the manager's repository, possibly far beyond the 100 enrichments available in the preview. The enrichments will be made available as notifications in a dedicated section in the Content Provider Dashboard UI to be further checked as well as through the broker service API for programmatic access.
Notifications will be sent to subscribers every time the OpenAIRE Graph will be updated and analyzed to derive the enrichments.
