HTTP Requests are accepted and validated by a series of RestControllers. The responsibility of these RestControllers is to accept requests, parse parameters, and check all possible pre-conditions. They also connect the various HTTP requests to the appropriate CTS2 Profile Interfaces

. Once the RestControllers have accepted the requests and identified the needed CTS2 Profile Interfaces to fulfill it, The process of discovering the available implementations of those needed CTS2 Profile Interfaces begins.

5 URI Resolution

One of the requirements of Resource Oriented Architecture is that every resource must have an identifier. As the Universal Resource Identifier (URI) is the primary identifier used by the Semantic Web, the CTS2 specification calls for all of its resources to be identified by URIs. This results in the need to distinguish the identity of the resource being described from the identity of the description itself, and the basic requirement that all servers in a CTS2 ‘ecosystem’ need to use the same identifiers if information is to be aggregated and shared in a meaningful fashion. The EVS solution for this problem is a URI resolution service, which provides a canonical URI for any local URI and does so as a service.  For the EVS implementation of this service, a URI Resolver Service has been implemented and runs in conjunction with the EVS CTS2 implementation.  While CTS2 users may install their own resolving service, based on the installation instructions here, a service is also running at this location.  A thorough description of this service is to be found here.

Service Plugin: An OSGi bundle capable of being loaded into the CTS2 Development Framework. In order to be recognized as a Service Plugin, the bundle must export one (and only one) Service of type ServiceProvider

. Note, however, that the bundle is no excluded from exporting other services – but it must at least export one and only one ServiceProvider Service.
