DAB Profiler Development KIT (PDK)

The Profiler Development KIT (from here "PDK") provides a complete Java API which allows to develop the so called DAB “profilers”. Profilers are the front-end components of the DAB (Discovery and Access Broker), and they expose and handle its service functionalities. PDK allows to develop the front-end of a Web service focusing only on its business logic and service interface specification, while the endpoint publication and the backend functionalities are completely handled by underlying layers of the DAB. The DAB provides several profilers, each of which implementing a different Web service interface conforms to different specifications (standard and non), such as CSW 2.0.2, OAI-PMH 2.0, OpenSearch, etc. This document describes the general architecture of the PDK along with the definition of the main components of the Java API, with a focus on the “discovery interfaces” of the DAB
