Most of all, we need global identifiers for the different wikis. We
could add a table which only contains mapping of the local prefixes to
global identifiers, but we think that the current interwiki table
could use some love anyway, and thus we decided to restructure it as a
whole. This now has lead to the above mentioned RFC, but the original
blocker is: for providing language links form a central source --
Wikidata -- we need to have global wiki identifiers.
In some ways we already have that. There is the iw_wikiid field added for
the gsoc project which was never merged. wiki ids should be unique
within the wikifarm (since they correspond to db names)
I probably misunderstand. If currently something is
not set up as an
interlanguage link and neither as an interwiki link, it will become a
normal link, not an interwiki link (i.e. it will point to the local
page foo:some page in the main namespace). Did you mean something
else?
Interlanguage links are only interlanguage on subject namespace pages.
On talk pages they're normal interwikis so a link that is only an interlanguage
and not an interwiki does not make sense.
I would really like to see the interlanguage stuff re-done. Preferably with
a means to configure multiple types of interwikis-that-go-in-sidebars
so people could have interproject links and what not. Commons might
have a section (portlet) in the sidebar for each of the sister
projects, and each section
contains the language links for that project
The issue I was trying to deal with was storage.
Currently we 100% assume
that the interwiki list is a table and there will only ever be one of them.
Do we
really assume that? Certainly that's the default config, but I
don't think that is the config used on WMF. As far as I'm aware,
Wikimedia uses a cdb database file (via $wgInterwikiCache), which
contains all the interwikis for all sites. From what I understand, it
supports doing various "scope" levels of interwikis, including per db,
per site (Wikipedia, Wiktionary, etc), or global interwikis that act
on all sites.
We did not know about that database. Who can tell us more about it?
This would be very interesting to get our synching code optimized.
It still wouldn't help us with the global identifiers, though, but it
would be good to know more about it.
I've tried to add a brief bit on the RFC page (mostly gleaned from the docs), I
was kind of rushed though. Its basically a cdb file that has all the interwiki
links for several wikis.
