Hi all,
As promised a while ago, we have reworked our "Wikidata Classes and Properties" browser. I am happy to introduce the first beta version of a new app, called SQID:
http://tools.wmflabs.org/sqid/
It is a complete rewrite of the earlier application. Much faster, more usable, much more up-to-date information, supported on all reasonable browsers, and with tons of new features. Try it yourself, or read on for the main functions and current dev plans:
== Browse classes and properties ==
You can use it to find properties and class items by all kinds of filtering settings:
http://tools.wmflabs.org/sqid/#/browse?type=properties http://tools.wmflabs.org/sqid/#/browse?type=classes
New features: * Sort results by a criterion of choice * Powerful, easy-to-use filtering interface * Search properties by label, datatype, qualifiers used, or co-occurring properties * Search classes by label, (indirect) superclass or by properties used on instances of the class * All property statistics and some class statistics are updated every hour
== View Wikidata entities ==
The goal was to have a page for every property and every class, but we ended up having a generic data browser that can show all (live) data + some additional data for classes and properties (this is our main goal, but the other data is often helpful to understand the context). The UI is modelled after Reasonator as the quasi-standard of how Wikidata should look, but if you look beyond the surface you can see many differences in what SQID will (or will not) display.
Examples: * Dresden, a plain item with a lot of data: http://tools.wmflabs.org/sqid/#/view?id=Q1731 * Volcano, a class with many subclasses: http://tools.wmflabs.org/sqid/#/view?id=Q8072 * sex or gender, a frequently used property: http://tools.wmflabs.org/sqid/#/view?id=P21
Notable features: * Fast display * All statement data with all qualifiers shown * Extra statistical and live query data embedded
== General Wikidata statistics ==
As a minor feature, we also publish statistics on the weekly full Wikidata dump (which we process to get some of the statistics):
http://tools.wmflabs.org/sqid/#/status
Don't trust the main page -- find out how many entities there really are ;-)
== Plans, todos, feedback, contributions ==
We are on github, so please make feature requests and bug reports there:
https://github.com/Wikidata/WikidataClassBrowser/issues
Pull requests are welcome too.
Known limitations of the current version:
* Data update still a bit shaky. We refresh most statistical data every hour (entity data is live anyway), but you may not see this unless you clear your browser cache. This will be easier in the future. * Entity data browser does not show sitelinks and references yet. * Incoming properties not shown yet on entity pages * I18N not complete yet (if you would like to try the current dev status, see, e.g.: http://tools.wmflabs.org/sqid/#/view?id=Q318&lang=de)
Moreover, we are also planning to integrate more data displays, better live statistics, and editing capabilities. Developers who want to help there are welcome. SQID can also be a platform for other data display ideas (it's built using AngularJS, so integration is easy).
== And what about Miga? ==
The old Miga-based app at http://tools.wmflabs.org/wikidata-exports/miga/ will be retired in due course. Please update your links.

I have had important development support from Markus Damm, Michael Günther and Georg Wild. We are funded by the German Research Foundation DFG. All of us are at TU Dresden. Complex statistics are computed with Wikidata Toolkit. Live query results come from the Wikidata SPARQL Query Service.
Enjoy,
Markus
