Publication & Discovery

For a data space to create value, participants must be able to publish what they offer, and others must be able to discover it easily. iSHARE provides a framework for the discovery of:

• (Data) Services. All participants providing services must provide a /capabilities endpoint, as defined in the developer documentation. This endpoint provides information on the available iSHARE service offerings.

• Participants and Data Spaces: participants of an event, complete data spaces are discoverable through the /parties endpoint or /dataspaces endpoint of any iSHARE Participation Registry.

• Although partly covered in the iSHARE Trust Framework, the data space is free to define supplemental agreements or specifications on top of or following the DSSC building block.

Figure 18.iSHARE-Based Service and Participant Discovery.

Publication and Discovery connects closely with other building blocks:

• Data Space Offering: Describes the data and services offered.

• Regulatory Compliance: Covers rules for data intermediation services.

• Data, Services and Offerings Description: Manages offerings for publication and discovery.

• Value Creation Services: Publishes available services via the Publication and Discovery building block

The guiding questions can help in the co-creation process and in defining this building block, so please see the next section.
