The FrancoToile RNG schema needs to be updated to include latitude and longitude information, so I generated a new schema from the TEI Roma application ( http://www.tei-c.org/Roma/ ). It turns out that a small handful of the conventions used in the FrancoToile data files are no longer valid, namely: date/@value is now date/@when persTrait is now trait dateline needs to be within a closer element So, I've fixed these issues in the data files, which now valid against the new schema. And, now that the schema contains support for latitude/longitude, those values can be added.
