Well, until we've figured out a story in GNOME for how "social
networks" are integrated, it just doesn't make sense to add this to
GOA. The more general observation (of which the above is a
specialization of) is that we do not add support for providers P (e.g.
Google, Facebook) or services S (e.g. Documents, Mail, Chat, Calendar,
1. we know how it's going to be used in a GNOME release; and
2. there is something in the GNOME release using it.
Basically: you need to work with the GNOME Designers on figuring out
how "social networks" fit in.
For GNOME 3.2 we have the following users:
- Empathy / GNOME Shell (Chat)
- Evolution (Mail, Calendar)
- GNOME Contacts (Contacts)
- GNOME Documents (Documents)
and we still only support Google as a provider. Why? Because Google is
right now the only provider where
a) we can use anonymous API keys; and
b) we have support for Google in the above-mentioned apps
The other problem is how to handle API keys. As I have mentioned
before on this list and elsewhere, a couple of months ago I sent a
long mail with legal questions to the GNOME Foundation and I'm still
waiting on a response. Basically, we want to be able to legally ship
API keys along with GOA. So it boils down to this: even if we had all
the protocol support for, say, Facebook in, say, GNOME Contacts
(through libfolks) and Empathy (through Telepathy) we would not be
able to turn it on because of unresolved API key and legal questions.
> Are there plans for making service providers in GOA pluggable?
Not at this point, no, and probably not in the future either. Why? Two reasons
I. Adding support for a provider P, currently means making code-changes to
all of the GNOME apps using its services.. because most of the time standard
standardized protocols are not in use. For the few cases where it
uses a standard
protocol (such as XMPP and IMAP/SMTP) we could support pluggable providers.
For example, we could, presumably, read "plug-in" files from some directory
so we could list 200 different XMPP chat services or 200 different
That that no-one ever heard about. But would we want the user to
see this? The
answer is: not in GOA. But see II. below
II. To avoid user confusion we only want the major online services in GOA.
Support for more specialized protocols/services should happen in each
separate app - that's why, for example, that Empathy still has a preferences
menu so you can add support for e.g. ICQ, Zephyr and other fringe chat
services and protocols. And that's also why you still have support in
Evolution for manually adding IMAP/SMTP servers.
I will try and add some of these guidelines (or "rules" if you want)
to the GOA documentation, see
for what it looks like right now.
