This section provides an overview of the NetworkedPlanet Constraint Language (NPCL) Web Services. These services are implemented both as SOAP web services and as simple HTTP GET/POST interfaces which allow connectivity from AJAX applications. This section starts with an overview of the operations that the NPCL Web Services provide, described in terms of their input parameters, processing and output. There then follows a description of how these are mapped to a SOAP web service interface and to an HTTP interface.

In the following service descriptions, elements with the namespace prefix 'npcl' come from the NPCL XML Schema and the prefix is assumed to be mapped to the namespace URI 'http://www.networkedplanet.com/schema/npcl'. Elements with the prefix 'nf' come from the NPCL Forms XML Schema and the prefix is assumed to be mapped to the namespace URI 'http://www.networkedplanet.com/schema/npcl-forms'.
