I want to create atom xml representations for my REST resources using Restlet.
Should I (can I?) use ROME or just use the Atom extension for Restlet?
What's the best way to go about this?
Thanks in advance.
The best way is usually what suits your needs best :)
If you want to be up and running fast, you may prefer to use a helper library. Here I would also suggest to take a look at Apache Abdera.
The part that may be of concern with helper libraries is usually the number of external dependencies. If this is a deal breaker for you, then you may want to consider to write the code yourself.
