Hey everyone, it seems we're getting new properties every day. Currently there are over 2000 properties on Wikidata, and for me personally it's becoming a bit difficult to see the forest through the trees. Of course there are a couple of places where they are listed, but they're either a bit unwieldy ([1]), broken ([2]) or not detailed enough ([3]).
Anyway, code is better than complaining so i hacked up a tool: https://tools.wmflabs.org/hay/propbrowse/
You can filter the list by typing in a couple of characters, see either a detailed or compact list and it's possible to sort the list by different properties (id, label, example, etc.).
This list is updated every night and code is available on Github ([4], [5])
Let me know if you think is useful and if there's anything you're missing.

Well done! Absolutely love it! I'm already using it to build SPARQL queries for the wikidata visualizations [1].

Now I suddenly understand why we should have "properties for properties" so we can categorize these things. It would be nice to have a list of "authority control" properties and also the number of times a property is used.
Maybe there is a way to organize the metadata so a "property property" is unnecessary and another "category-like" tool can be used to split these up - maybe a hierarchy map?

You can already do that in propbrowse. Just filter for 'unique identifier' and you'll get all properties that are an instance of Q19847637 (Wikidata property representing a unique identifier).
Considering number of times a property is used:i think that would be really interesting. Unfortunately, i don't know of a way to easily get a count of how many times a property is used. The 'linkshere' functionality in the API doesn't give a count.

Filtering by usage count is something we already have in Miga. For example, here is a list of authority control properties that are used at least 1000 times on Wikidata:
http://tools.wmflabs.org/wikidata-exports/miga/#_cat=Properties/Related%20pr...
Currently requires Google Chrome or Opera to view. We are about to reimplement this application completely to make it use live data and be compatible with all browsers. Should be ready later this month.
Regarding the data source, we will use a mix of live data and cached precomputed data for more expensive statistics that you cannot query for every second.

Is this sill an issue or did a usable method come up later on in this thread?
Anyway, as an approximation, this can be taken from the weekly dumps. My filter writes (amongst other this) a TSV file of these. Last week's top three were:
<pre> -[ RECORD 2127 ]---------------------- prop | P21 def_cnt | 1 use_cnt | 2866032 datatype | wikibase-item label_en | sex or gender descr_en | Sexual identity of subject. Main: male (Q6581097), female (Q6581072), transgender female (Q1052281), transgender male (Q2449503). For animals, use male animal (Q44148), female animal (Q43445). For groups of same gender, use "subclass of" (P279) -[ RECORD 2128 ]---------------------- prop | P17 def_cnt | 1 use_cnt | 4055618 datatype | wikibase-item label_en | country descr_en | sovereign state of this item -[ RECORD 2129 ]---------------------- prop | P31 def_cnt | 1 use_cnt | 15152571 datatype | wikibase-item label_en | instance of descr_en | this item is a specific example and a member of that class. Not to be confused with Property:P279 (subclass of). </pre>

I suspect that https://query.wikidata.org can count how many times each property is used. On Feb 14, 2016 17:54, "Jane Darnell" jane023@gmail.com wrote:

This shows the counts of *all* 8000+ properties used in the RDF store. Looking for the appropriate URIs, you can read off each Wikidata property's uses in statements, quantifiers, and references individually. I am impressed by how well BlazeGraph is handling this.

I would just filter this in code; a more complex SPARQL query is just getting slower. Here is a little example Python script that gets all the data you need:
https://github.com/Wikidata/WikidataClassBrowser/blob/master/helpers/python/...
I intend to use this in our upcoming new class/property browser as well. Maybe it would actually make sense to merge the two applications at some point (the focus of our tool are classes and their connection to properties, as in the existing Miga tool, but a property browser is an integral part of this).

Would it be possible to set the language used to search with? Whilst I most often use English on Wikidata I'm sure a lot of people don't.

Not yet. The query takes quite a while, so it's done in realtime but every 24 hours, and then it's compiled to the HTML list. Adding multi-language support would be a bit more cumbersome. I'm open to pull requests though ;)

Yes, as usual: it is easy to support *any* language, but tricky to support *all* languages.

We shall see. For now, it is certainly not obsolete. There might also be different tools with different specialisations.

Tricky to support *all* languages how, Markus?
(CC WUaS in Wikidata seeks to be in all 7,943+ languages per Glottolog, beyond Wikipedia's 300).
Thank you, Scott

Would it be possible to set the language used to search with? Whilst I most often use English on Wikidata I'm sure a lot of people don't.
Not yet. The query takes quite a while, so it's done in realtime but every 24 hours, and then it's compiled to the HTML list. Adding multi-language support would be a bit more cumbersome. I'm open to pull requests though ;)
Yes, as usual: it is easy to support *any* language, but tricky to support *all* languages.

I would just filter this in code; a more complex SPARQL query is just getting slower. Here is a little example Python script that gets all the data you need:
Ah, excellent. In that case i'll just do a query and filter in Python.
I intend to use this in our upcoming new class/property browser as well.
Maybe it would actually make sense to merge the two applications at some point
I hope the propbrowser will be made irrelevant by improvements in other tools and the main Wikidata site ;)
We shall see. For now, it is certainly not obsolete. There might also be different tools with different specialisations.
