Common Services - Q4 2022
Summary
In this chapter, the identified Common Services, necessary for the proper execution of the Evidence Exchange process, are described in detail, providing the information model and their technical design documentation. To achieve organisational interoperability, several functions have been identified that need to be available either centrally or at MS level as described in section 6.6 of the OOTS HLA, to execute the business processes of discovering and getting the required evidence. The identified Common Services are:
- The Data Service Directory (DSD), which is a common service that acts as a catalogue of Evidence types that the EPs can provide upon request. It is used in the Evidence Exchange process by the Evidence Requesters to discover the Evidence Providers that can provide the evidence they require.
- The Evidence Broker (EB), which is an authoritative system that maps specific data sets as Evidence types that prove specific requirements. The ER consults the EB to find which types of evidence can be requested as evidence for a specific Evidence Subject, taking into account the Subject's location and/or jurisdiction.
- The Semantic Repository (SR) is a common service that acts as a data portal for OOTS, storing commonly agreed information models grouped by domain, providing them under multiple representation techniques.
