There are several open source offerings like this, Talend is another one that comes to mind.
I haven’t looked at its data integration in detail but suspect I know the answer to the question:
Say I have an integration of some BI assets using Pentaho and other BI assets integrated using Talend, how do I integrate those together while maintaining the separately integrated BI assets?
Or for that matter, how do I integrate BI that has been gathered and integrated by others, say Lexis/Nexis?
Interesting too to note that this is the sort of user slickness and ease that topic maps and (cough) linked data (see, I knew I could say it), faces in the marketplace.
Does it offer all the bells and whistles of more sophisticated subject identity or reasoning approaches?
No, but if it offers all that users are interested in using, what is your complaint?
Both topic maps and semantic web/linked data approaches need to listen more closely to what users want.
As opposed to deciding what users need.
And delivering the latter instead of the former.
