GCat Service

The gCube Science Catalogue Service is a RESTful web service based on the principles defined in gCube Catalogue

Request

URL

The URL used to interact with the Science Catalogue Service is composed of two parts:

• Base Service URL (e.g. https:/catalogue.d4science.org/science-catalogue)
• Specific API (e.g. /organizations)

D4Science infrastructure uses cloud facilities allowing to replicate a service to achieve failover and load balancing.

Science Catalogue Service instances can be deployed and undeployed dynamically. For such a reason the Base Service URL MUST NOT be hard-cabled in the code because it can change over time.

To dynamically discover the Base Service URL please use the information system.
