ICS-D is the distributed component of ICS. ICS-D characteristics are documented in the metadata catalog and ICS-C utilises the user request and the catalog to generate a workflow to be deployed and executed across ICS-D using computing resources in the TCS environment and the e-I (e- Infrastructure) environment external to EPOS. ICS-D may be a distributed computing or sensor platform (whether in the field or in a laboratory) and also may be specialised software services integrated with a distributed computing platform e.g. for analytics, simulation or visualisation. We specify the updated elements of the characteristic description of ICS-Ds to be included in the catalog and the plan for the integration.
