Because BaseX was missing from the list at http://nosql-database.org/ , I took the liberty of adding it. There was a 330 char limit on the description, so I swiped some stuff from the home page and tightened it up to fit. If anyone at BaseX would prefer a different description, let me know or send it to the folks at nosql-database.org.
And congrats on the latest release. Good features and reliability, Java, and the ability to use BaseX with Maven make it my XML DB of choice.
