What open format-based genealogy software do you know?
I am making a research of available genealogy program and was a bit disappointed with the results. I am seeking tools which would be feature-rich, agile and extendable at the same time. The main requirement for me is format in which app stores genealogy records. It should be open, extendable (e.g. XML-based) and have high-performance (for handling 100 000+ records). Having reviewed genealogy market I didn't found worthy alternatives. The main candidates which meet my requirements are:
GRAMPS (Berkeley DB)
RootsMagic (SQLite 3)
GeneWeb (text)
Actually GeneWeb is not fully complies with my requirements as its format is plain text. And the prime cause of my GEDCOM abandonment and drifting towards opennes is that GEDCOM, as other text formats, is often ambiguous and could be inconsistent - it is read by different apps in a different way. But, nevertheless, let it be for the sake of completeness.
In spite if embedded DB (SQLite) in RootsMagic, I was completely discouraged by RootsMagic features. It even have no out-of-the-box export other than GEDCOM! So, currenty, GRAMPS is #1 candidate in my list.
Actually, I was overwhelmed with the range of available open-format software - it is inexcusably small!
So I am asking for your advice: what other alternatives to above 3 apps could you propose to me?
Web-based ones engines (like Webtrees) are also appreciated.
