Introduction to the CAS Extension API

System requirements
The CAS Extension API requires the following software installed on the system where you develop CAS extensions:

Overview of the CAS Extension API
The CAS Extension API provides interfaces and classes to build extensions to CAS such as data source extensions and manipulator extensions. An extension developer packages extensions into a JAR and a CAS application developer installs the JAR and any additional JARs (for third-party dependencies) into the Content Acquisition System. After installation, the extensions are available and configurable using the CAS Console, the CAS Server API, and the CAS Server Command-line Utility.

Common record properties
The CAS Server generates certain properties whether you acquire data from a file system, a CMS, or custom data source.
