No, of course I didn't finish it, but at least there is something to build on if anyone wants to take a look at things while I am waiting for my somewhat overdue shipment of appropriately shaped tuits. The appropriate files are Gedcom::Comparison and gedcom_compare. This tries to provide a probability of two records matching based on the probabilities of each record's sub records matching. From just looking at it right now, two obvious improvements that are required are to compare actual dates rather than their textual representations, and to match other textual records in a somewhat finer graduation than 0% or 100%. -- Paul Johnson - [email protected] http://www.pjcj.net
