While I realize this project hasn't seen any maintenance updates in a long time, it'd be nice to move it to a different Java ATOM API (to avoid future security issues, etc). One example might be ROME: https://rometools.github.io/rome/
Without such an update, projects using SWORDv2 (like DSpace) may eventually need to move away from it, as maintaining an integration with abandoned dependencies becomes more and more difficult.

However, it's used heavily by this JavaClient: https://github.com/swordapp/JavaClient2.0/blob/master/pom.xml#L164-L168
