I like the idea of geo location. however, If I look after the 12 OpenERP
projects I participated, I think barely 4 or so would care about such a
thing.
At the end, I tend to think the following:

   - as we already talked recently we don't have any EAV framework (
   http://en.wikipedia.org/wiki/Entity-attribute-value_model ) in OpenERP
   currently, meaning every new core field will bloat the whole ERP, so would
   GIS coordinates (not sure if those would be eligible to EAV here but if some
   other fields were to, then adding fields would be easier anyway).
   - so if we start adding right into the core fields that are debatable, we
   open the door to people asking a lot more somewhat useful fields that might
   be just as useful as GIS (or even more) in the name of consistency.
   - yes OpenERP still makes it a pain in the ass to add extra fields by
   means of modules inside business objects such as sale.order.line,
   invoice.order.line, stock.move or account.move.line in
   a consistent way across all other existing modules (of course you often
   manage to get your key process working, but that's not the same than overall
   consistency), because those objects tend to be instantiated in lots of
   places sometimes in fat dirty non over-ridable methods (although I had some
   basic clean up merged in v6 fortunately). So this justify the to add fields
   in those objects right into the core, until OpenERP standard addons make it
   easier to do that with modules. I think this the reason why the double unit
   management is implemented into the core for instance, although largely
   broken (we can discuss that later eventually if you want to clean it for v6,
   we did some stuff in v5). Now, objects like partners and addresses are
   not instantiated so much in large dirty non over-ridable methods. This means
   that we could add it in a standard base module.

At the end, I'm not telling that GIS shouldn't be into the core, I'm just
telling: because of some OpenObject current limitations, we do have a "field
scalability issue" and a limit should be put somewhere, I'm pretty sure that
GIS related fields are close to that limit. On the contrary, unlike other
business objects, partners and addresses seems pretty easy to extend in a
module. So may be a solution could be to add a standard addons module adding
those properties. BTW, if you guy implement my idea of degradable iframes to
URL's into the GTK clients, a cool feature would be a Google Map view of the
partner location right into the partner view that would degrade to a link
into a link to the map in the GTK client.

Thoughts?
