The data is stored in the bundle cache. More specifically, in the bundle cache of the repository
implementation (org.apache.ace.repository.impl). It is possible to locate this cache on disk,
and you will find binary blobs there. They are gzip'ed, and if you unpack them you will discover
XML data.

In theory, you can edit that data directly, but I would strongly discourage that as this is
an internal format that we have and in the future will change if necessary. Really your best
bet is to manipulate this data through one of the three clients we have:

 - Web UI (you already stated you don't want to use that)
 - REST client API (a set of REST endpoints)
 - GoGo Shell client API (a set of commands for the built-in GoGo shell)

All of these build on a set of Java Client APIs.

If you want some kind of declarative format for specifying the data you want to put in ACE,
my suggestion would be to define such a format and then write some code to take that format
and put it in ACE using the Java client API (probably taking one of the three existing clients
as an example).

However, perhaps you should explain your use case a bit more before I start giving the wrong
advice. :)

Greetings, Marcel
