Genealogy Namespace for OPML?

In my effort to organize the collection of family tree data I’ve acquired in the past week, I’ve tried out a number of proprietary software applications – some worse than others.

Currently all my data is in a free application that imports and exports the Church of Jesus Christ of Latter-day Saints’ GEDCOM format. The application isn’t the easiest to use nor is the format itself.

OPML is pretty good at describing relationships and their associated attributes. Maybe all this family data is just an OPML namespace.
