[Foundation-l] Wikidata: wiki-style databases

Excerpt from

http://meta.wikimedia.org/wiki/Wikidata

Wikidata is a proposed wiki-like database for various types of content.  
This project requires significant changes to the software (or possibly a  
completely new software) but has the potential to centrally store and  
manage data from all Wikimedia projects, and to radically expand the range  
of content that can be built using wiki principles.

Imagine that you can edit the content of an infobox on Wikipedia (e.g. the  
country box for Germany) with one click, that you get an edit form  
specific to the infobox you are editing, and that other Wikipedias  
automatically and immediately use the same content (unless it is local and  
needs to be translated).

Imagine that some data in an article can be automatically updated in the  
background, without any work from you - whether it is the development of a  
company stock, or the number of lines of code in an open source project.

Imagine that you can easily search wiki-databases on a variety of  
subjects, without knowing anything about wikis.

This project is separate from the Wikimedia Commons, because a Wikidata  
database does not necessarily have to be useful for another Wikimedia  
project, and because it is larger in scope.

Applications

* astronomical objects
* constellations
* craters
* observatories and telescopes
* surveys
* space missions

Society - '''society.wikidata.org'''
* Schools and universities
* Cities, Countries, Subdivisions
* Ethnic groups
* Radio and television stations

----------------------------------------

Jimmy has just registered wikidata.org. We both agree that such a project  
makes sense. I've had similar ideas before, but the (IMHO premature)  
existence of Wikispecies has compelled me to put some of this down and  
develop the idea further.

There's a GUI mock-up on the meta page of what data entry could look like,
and there's a (very rough) proposed implementation strategy. If someone is
willing to do so, it may make sense to create a proof-of-concept from
scratch.

I'm putting this idea out there for now so that it can be picked up at any  
later time. This is not urgent in any way, but it could open up a huge new  
range of projects where Wikimedia can compete with proprietary content  
producers. (Oh, and corporate users of MediaWiki would love us for this.)

----------------------------------------

I see two immediate consequences for us:

1) I believe that, if we do a database redesign, the needs of a project
   like Wikidata should be considered; that is, we should come up with an
   abstract scheme that allows storage and revision-handling for many
   different data structures. Otherwise we'll have to do another huge
   conversion later.

2) For Wikispecies, I suggest that those involved with the project make
   sure that all data entered into the wiki is in a *structured form* so
   that it can then later be easily converted into a real database
   structure.

Regards,

Erik
