The Data Space Connector Report is a key regular publication from the International Data Spaces Association (IDSA) offering a comprehensive overview of Data Space Connectors and their role in interoperable data spaces. In particular, the Data Space Connector Report: highlights the importance of Data Space Connectors, explaining what they are and why they are a key element in data spaces. It provides a summary of all the key requirements to make Data Space Connectors interoperable (e.g. relying on standards, having clear specifications, enabling semantic interoperability via the Data Catalog (DCAT) vocabulary and specific vocabularies, etc.) based on the DSP. It is the reference point for learning and fostering interoperability in data sharing ecosystems. The Data Space Connector Report aims to focus on the above-listed topics, therefore details on International Data Spaces use cases are not in scope. For a deep dive into those topics, please refer to some complementary IDSA resources: www.internationaldataspaces.org Regarding the topic of use cases: Please refer to the Data Spaces Radar: www.dataspaces-radar.org/radar. It is an interactive tool created by IDSA in the context of the Data Spaces Support Centre (DSSC) to offer an overview and quick information on several data spaces initiatives and use cases, highlighting their different implementation stages, domains and providing several additional details. The information is constantly updated by IDSA within the Data Spaces Support Centre project.
