The aim is to make Birman genealogy easier to research without hiding uncertainty.
The source
Pedigrees, catalogues, registries and other records are photographed, imported or entered.
The record
Information is normalised while original spelling and provenance can be preserved.
Provenance
One cat may have several sources, showing where each piece of information came from.
Duplicate control
Name variants, registration numbers, dates and relationships are compared before records are merged.
Search
Visitors search first; only relevant cats are then loaded instead of the whole database.
The family
Parents are shown graphically, unknown ancestors stay unknown, and descendants can be followed further.
Most important: a source is not the same as truth
A gap is not filled with a guess. Unknown fields remain unknown until documentation appears.
OCR errors and doubtful links should be checked before they are presented as certain.
Provenance lets us filter material without deleting the historical core.
