eXist Open Source XML Database

eXist is an open source XML database that is quite rightly attracting a lot of interest. There are many databases available that provide XML features as an 'add on', but there are very few that deal with XML natively. Built right into the heart of the database is the ability to search for data using XPath and XQuery, to store and retrieve XML without having to convert it in any way, and most importantly, access to all of this is achieved via RESTful interfaces. This makes eXist ideal for any application that is XML from beginning to end, since the client can store and retrieve data from the database without the need for an intermediate layer.

eXist forms a key part of our web application philosophy, based on the ideas of skimming. [Link to a skimming page, as well as talks I've done that have featured eXist.]
