Thread: Geneology: GEDCOM and PostgreSQL
I am getting interested in creating a web application for collaberativly compiling family trees. Of course this is not a new idea, but I can't find much good open-source code about, and I don't trust any of the existing services not to go bust. My first task is to build a solid data model. GEDCOM[1] is a data exchange format developed by the Mormons (who consider genealogy to be a 'religious obligation'[2]). Together with it's XML translation GedML[3], GEDCOM seems to summerise the standard data model which is used by genealogists. I have a few questions: Has anyone produced an Postgres-style SQL translation of the GEDCOM data model? Are there any existing Postgres-based genealogical tools? Is there anything I should know about Postgres's handling of the inevitable tree traversal queries? (Is there anything like the Oracle connect by syntax?)

I don't think it supports Postgres, IIRC, but it might be something to start with. -- hackers ally
