Integration
eXist provides many APIs, each of which allow you to integrate or interact with eXist
in a different manner. Multiple APIs are provided in the hope that at least one of
them is already supported fin the system or application that the developer or user
wishes to integrate with eXist.
eXist provides two classes of API:
Local APIs
These are intended for when a developer wishes to embed eXist as a library
within his own application running on the JVM.
Remote APIs
These are intended for when eXist is run as a server and a user or application
wishes to make requests to eXist. All of the remote APIs are developed as layers
atop HTTP. There is nothing to stop you from using a remote API from the same
machine that eXist is running on.
We have found that the majority of eXist users are interested in the remote class of
API, as they wish to use eXist as a database server and/or a web application server, so
we will focus on the remote APIs first.
Choosing an API
As you are about to see, eXist offers many options for integration with existing sys‐
tems and programming languages. Choosing the right one can be confusing, so we
have produced the flowchart in
Figure 13-1
to help you with your decision.
