Thank you for this pull request @pieterprovoost

In case you weren't aware, there is a set of unit tests related to DCAT generation: https://github.com/gbif/ipt/blob/master/src/test/java/org/gbif/ipt/task/GenerateDCATTest.java

I would have expected an update here to ensure that non published datasets don't get included in the feed - can you please take a look? Thanks for your help.

This doesn't impact DCAT, just RSS. I'll try to add a unit test in https://github.com/gbif/ipt/blob/master/src/test/java/org/gbif/ipt/service/manage/impl/ResourceManagerImplTest.java

Sorry @pieterprovoost you're right, my mistake. Adding a test for the 'latest' method would be a valuable addition if you could make that, thanks again for your help.

[pieterprovoost]

I have made a few more changes and added a test for latest(). RSS feed generation now only checks the last published version of a dataset.

Thank you very much @pieterprovoost, that was perfect. Are there any other pressing issues that you need fixed?

[pieterprovoost]

@kbraak No, just that one, thanks.
