1. Overview
The Evidence Broker is one of the Common Services of the OOTS HLA. It is a service that publishes which types of evidence Member States can provide to prove a particular requirement of a procedure. It provides metadata on the requirements applicable in a procedure and which type of evidence can be used by the User to prove fulfilment. Using the mapping from criteria or information requirements to possible evidence types, the Evidence Requester can find the evidence types that can prove that the User fulfills the requirements of the procedure.
The information data model is based on the OOTS generic metadata model and its Application Profile for the EB. The Service API is implemented using the OASIS RegRep 4.0 Query Protocol with the REST API Binding. The Life Cycle Management is implemented using the RegRep 4.0 LCM Manager Interface Specification SubmitObjects Protocol using eDelivery for secure and reliable messaging.
In the following sections, a detailed analysis of the internal data model, the Service API specification and the Life Cycle Management specification are provided.
