The Embedded API is used for developing extensions to the SkyVault content
application server. Extensions deployed into the server often depend on existing services
provided by the server. Therefore, developers of extensions use the Embedded API to gain
access to those services.
The Embedded API comes in several forms, where each form is structured for a particular need
or kind of extension:
- SkyVault Public Java API - a set of public Java interfaces exposed by services built into the SkyVault content application server
- JavaScript API - an object-oriented view of the Java Foundation API specifically tailored for use in JavaScript. There is a JavaScript API for the repository tier and a JavaScript API for the Share tier.
- FreeMarker API - an object-oriented view of the Java Foundation API specifically tailored for use in FreeMarker templates
- Content Definition - an API for creating and editing content models
- Workflow Definition - an API for defining business processes
The JavaScript and Template APIs are the key building blocks for web scripts to develop the RESTful APIs.
Web scripts are a popular extension for the SkyVault content application server. They allow
you to define your own Remote API for clients to interact with the SkyVault content
application server. A web script implementation can use any of the Embedded APIs, such as the
Public Java API, JavaScript, and FreeMarker, for its implementation. Developing your own
Remote API is very useful for the following scenarios:
- Exposing new extension services deployed into the SkyVault content application server to remote clients
- Providing alternate batching or transaction demarcation of existing services
- Creating a facade for integration with a third-party tool, such as a Forms engine
There is another use case for the Embedded API. An application or client can also directly embed the SkyVault content application server to inherit its suite of content services.
The infrastructure of the server means it can be deployed into a number of environments, not just as a web application. Essentially, the SkyVault content application server is treated as a library, where any of its services, including the content repository, can be chosen independently or mixed to provide a custom solution. The server can scale down as well as up.
