Hi Francis,

Great to meet you the other evening, and welcome to the project.

I have a couple of ideas for small projects that might be a good
starting point for you, they would also give you some exposure to the
XQuery engine in eXist.

I would start by forking our repo to your own GitHub and getting
GitFlow installed locally, the details of that are here -
https://github.com/exist-db/exist#readme. You should create a GitFlow
feature for the feature you are adding.

You need to choose an IDE, eXist provides project files to support
IntelliJ, Eclipse and NetBeans out of the box, but you may use
anything you are comfortable with.

In terms of small projects, there are a few EXPath XQuery modules
(http://expath.org/spec/sql) that it would be nice to have fully
implemented in eXist. At present we implement just the HTTP Client
module and have a partial implementation of the Zip module. We also
implement the Packaging Module, but that is not an XQuery module.

I think it would be interesting to implement one of the SQL, File,
Binary Data or Zip modules. These are quite nice little projects as
XQuery modules in eXist are pluggable, and so you can pretty much code
this as its own little project within the eXist code base. You should
pick up some Java, JUnit and a little bit of Ant doing this. Not to
mention some XQuery. These modules are usually just wrappers around
common Java libraries.

If any of those interest you, in terms of what may be easiest, we
already have a partial Zip module, it just needs finishing so that it
meets the EXPath spec I think. Also eXist has it's own SQL module,
this could be copied and pasted and refactored to create one that
meets the EXPath spec.

When you have eXist, the modules are in
$EXIST_HOME/extensions/modules. Of course I would recommend having a
look at a few of the example apps that come with eXist, and perhaps
trying to store a few XML documents into eXist and query them with
XQuery before you start hacking. This may help you get started with
XQuery - http://en.wikibooks.org/wiki/XQuery


p.s. You may also be interested to know that Dmitriy's background is
in Accounting ;-)
