The catalogue contains a wealth of resources resulting from several activities, projects and communities including Blue-Cloud (https://blue-cloud.org/), i-Marine (www.i-marine.eu), SoBigData Research Infrastructure (www.sobigdata.eu). All the products are accompanied with rich descriptions capturing general attributes, e.g. title and creator(s), as well as usage policies and licences.
These services can be exploited both via web based graphical user interfaces and web based protocols for programmatic access, e.g. REST-API. OAI-PMH, CSW, WFS, SDMX. This offering nicely complements specific and community-specific applications.
