So far we've been ignoring the AGE tag.

Actually, both. We have discussed this recently, and
we are going to add Attribute field to both Event
and EventReference objects in gramps.

Event's attributes will be: cause, agency, etc
that is common to the event

EventReference attributes will be: age, father's/mother's
age (for family event) etc that is specific for each
event participant.

Once we add Attributes to the events, we will be easily
able to support any standard as well as custom event
attributes.

The somewhat outdated API docs are here:
   http://developers.gramps-project.org/devdoc/api/

The current API is here:
   http://developers.gramps-project.org/devdoc/api2.2/
and you need to aks it to "Show private" all the time,
because we started using an underscore symbol in module names.

The RelLib defines the core classes of gramps data.
The _ReadGedcom module in GrampsDb package is importing
gedcom files. Apparently, to successfully import something
we need it both to be a data piece defined in RelLib,
and have import code that places the data from gedcom
into that structure.

Please feel free to ask, contribute, etc.
In addition to the mailing list, we sometimes hang around
on the #gramps IRC channel at irc.freenode.net
