Hi!
I am new to WikiData. I wanted to know how can we get the json belonging to a category. Say I want to access the json belonging to Category 537. If I can get the Json, can you pls specify how I can access this json?
Main Aim: I want to know what Category 537 means and the sub categories and topics within this category.
Regards!
Hoi, I do not get it.. Wikidata has items not categories, so you get access to the item for a category in the same way as you get access to any other item. Thanks, GerardM

Hi Rohan,
if by category you mean "item", e.g. https://www.wikidata.org/wiki/Q537
the easiest way to get the corresponding JSON is: https://wikidata.org/entity/Q537.json
If you want a JSON object for all items with property P537, try: http://wdq.wmflabs.org/api?q=claim%5B537]
See here for many more options to interrogate Wikidata: http://wdq.wmflabs.org/api_documentation.html
Cheers, Magnus

Thanks for an early response.
@Magnus: I was able to get the json of the items. Still thanks. However, my exact problem is the following.
I had downloaded the wikidata dump from http://dumps.wikimedia.org/wikidatawiki/latest/ There is a file wikidatawiki-20140420-pages-articles-multistream-index which consists of triplets like:
537:114:Q17
which I interpreted as following: 537 - category of the topic (which I am unable to find. I want the details of this item) 114 - page_id of the item Q17. Q17 - which is the item. (JSON: https://www.wikidata.org/wiki/Special:EntityData/Q17.json)
I want to know whether my interpretation is correct. If it is correct, how can I get the details abt the category 537. If my interpretation is incorrect, how can I get the wikidata category to which an item belongs to?
Thanks and Regards!

I couldn't find documentation for the multistream-index format at https://meta.wikimedia.org/wiki/Data_dumps. I can't make sense of it myself offhand. Perhaps ask on the wikitech-l list. I suppose the authority on the question would be Ariel Glenn, perhaps you can get hold of him on IRC.

It's not a category. Wikidata doesn't use MediaWiki's Category feature for data items at all. Wikipedia does, but there pages generally have multiple categories, identified by name, not a numeric ID.
If you want to build a classification graph of the concepts in Wikidata (I'm intentionally avoiding the terms "ontology" and "taxonomy" here), you will have to go by the properties P31 (instance of) and P279 (subclass of) which are used in many (roughly half) of the data items.
114 - page_id of the item Q17.
That seems to be correct.
Q17 - which is the item. (JSON: https://www.wikidata.org/wiki/Special:EntityData/Q17.json)
It's the page title, which, on wikidata.org, is the same as the item ID.
HTH Daniel
PS: we are close to providing JSON dumps on a regular basis, and also make the JSON contained in the XML dumps more readable. This will hopefully make analyzing Wikidata less painful.
Q17 is Japan, and if you are interested in people from Japan for example, you can do this: http://tools.wmflabs.org/reasonator/?q=7463305 (thanks to Magnus' reasonator tool that can extract category-like info from Wikidata based on properties and qualifiers)

Jane, Lydia and WikiDatans,
These are great and helpful developments, which seem to be quite far along now.
Jane and WikiDatans, can you point to similar helpful examples that would distinguish how WikiData Categories and what one can extract with Magnus' reasonator tool from what one can 'extract' with SemanticWiki from WikiData Categories?
Lydia, are there any emerging video tutorials (in the manner of some of Google's, for example) of tutorials about WikiData Categories and/or Wikidata itself, in terms of making it very easy to use?
Thanks, Scott

Hoi, To confuse you even more, Reasonator knows about Wikipedia categories. What is so exciting is that it is possible to include statements in Wikidata that Reasonator interprets as statements for a query. Reasonator shows you the results from that query.
I blogged about a Mr Sinegal [1], in the article are links that include numbers, they show off that these queries are live and will show new numbers when either US musicians or musicians are added in Wikidata. Thanks, GerardM
PS I am harvesting information at this time, so you will see updates more or less every fifteen minutes.

Well, and of course some items are used as classes, which might be somewhat related to "categories" (in one of their many uses). For an overview of these, see
http://tools.wmflabs.org/wikidata-exports/miga/
To find instances of a particular class, you can then use the tools Magnus already mentioned.
Cheers,
