CDP4 Web API Introduction

The CDP4 Web API is an implementation of ECSS-E-TM-10-25 Annex C2. The CDP4 Web API is used to retrieve and update data from and to the CDP4 WebServices. This documentation describes CDP Web API as a vanilla ECSS-E-TM-10-25 Annex C2 implementation and does not take any of the CDP4 specific enhancements.

The CDP4 Web API makes use of a HTTP JSON REST interface. In order to retrieve data the GET verb is used. In order to create, update and delete data the POST verb is used.

The EngineeringModel class is not a singleton. One instance of the CDP4 WebServices may contain zero or more EngineeringModels.
