Looking for DITA:s to FrameMaker 12

Hello

We have decided to start using structured Framemaker and are now looking for
standard DTD/Ditas/Styles. Are such available, either for free or for
sale? Any recommendation is welcome.

We want to avoid to invent the wheel again, there must be a lot of good example out
there already.

Our preferences are that the documents will be managed through Sharepoint, published
in HTML5. There may be some requirement for translation support.

Thanks in advance
