I would also like to bring up the pending Wikidata API RFC at
http://www.mediawiki.org/wiki/Requests_for_comment/Wikidata_API
Thanks for pointing that out.
In that RFC I plan to unify Wikidata API to be more seamlessly
integrated with the core query API. Any feedback from pywiki community
is welcome.
If we can still functionally do the same what I described below you
probably won't get any complaints from this side. Is that the case?
Can you please include a period of overlap of old-style and new-style
api so we have time to update the framework?

Hi everyone,
As you might know phase 1 of Wikidata (interwiki links) is live at
a lot of Wikipedia's and soon to be turned on for all Wikipedia's.
Phase 2 is next, that's basically about infobox data. We are going
to need a lot of clever bots to fill Wikidata. To make that
possible Pywikipedia should (properly) implement Wikidata. That
way bot authors don't have to worry or care about the inner
workings of the Wikidata api, they just talk to the framework. At
the moment trunk has a first implementation that isn't very clean
and in the rewrite it's still missing.
Legoktm and I talked about this on irc. We need to have a proper
data model in Pywikipedia. Based on
https://meta.wikimedia.org/wiki/Wikidata/Notes/Data_model_primer :
* WikibasePage is a subclass of Page and has some basic shared
functions for labels, descriptions and aliases
* ItemPage is a subclass of WikibasePage with some item specific
functions like claims and sitelinks (example
https://www.wikidata.org/wiki/Q256638)
* PropertyPage is a subclass of WikibasePage with some property
specific functions for the datatype (example
https://www.wikidata.org/wiki/Property:P22)
* QueryPage is a subclass of WikibasePage for the future query type
* Claim is a subclass of object for claims. Simplified: It's a
property (P22, father) attached to an item (Q256638, the princes)
linking to another item (Q380949, Willem IV)
You can get these pages like a normal page (site object + title),
but you probably also want to get them based on a Wikipedia page.
For that there is
https://www.wikidata.org/wiki/Special:ItemByTitle/enwiki/Princess%20Carolina%20of%20Orange-Nassau
. We should have a staticmethod itemByPage(Page) in which Page is
https://en.wikipedia.org/wiki/Princess_Carolina_of_Orange-Nassau
and it will give you the itemPage object for
https://www.wikidata.org/wiki/Q256638. Currently in trunk the
DataPage object has a constructor where you can give a page object
and you'll get the corrosponding dataPage. I don't think that's
the way to do it because it violates the data model and will get
us in a lot of trouble later on when other sites (like Commons)
might implement the Wikibase extension.
A WikibasePage should work the same as a normal page when it comes
to fetching data. It should have the initial version (just a
title, no content) and once you use a function that needs data (or
you force it), it will fetch all the data from Wikibase and caches it.
* For an item the data looks like
https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q256638&format=json
* For a property the data looks like
https://www.wikidata.org/w/api.php?action=wbgetentities&ids=P22&format=json
Parts of the data (description, aliases and labels) should be
processed in the get function of WikibasePage, other parts in
ItemPage /PropertyPage
Based on the api we should probably have some generators:
* One or more generator that uses wbgetentities to (pre-)fetch objects
* A search generator that uses wbsearchentities
WikibasePage:
* Set/add/delete label (@property?)
* Set/add/delete description (@property?)
* Set/add/delete alias (@property?)
ItemPage
* Set/add/delete sitelink (@property?)
Claim logic
Not sure how we can use wbeditentity and wblinktitles
We took some notes on
https://www.mediawiki.org/wiki/Manual:Pywikipediabot/Wikidata/Rewrite_proposal
.
What do you think? Is this the right direction? Feedback is
appreciated.
Maarten
