# Publication & Discovery

{% hint style="warning" %}
**Note:** This page is currently being updated to align with the DSSC Blueprint 3.0 as well as the iSHARE Framework 3.0. An updated version will be published soon.
{% endhint %}

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](https://dev.ishare.eu/all-roles-common-endpoints/capabilities), 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](https://dev.ishare.eu/participant-registry-role/parties) or [ /dataspaces endpoint](https://dev.ishare.eu/participant-registry-role/dataspaces) 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](https://dssc.eu/space/BVE2/1071256989/Publication+and+Discovery) building block.<br>

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
