For a 200px thumb: https://upload.wikimedia.org/wikipedia/commons/thumb/x/xy/File_name.ext/200px-File_name.ext The SVG files are a special case, therefore .png is appended to .ext, being .ext.png. For SVG doesn't mind to use big thumb sizes, but when file is JPG, don't try to generate a thumb bigger than the original file or you will get a beautiful error.

I would like to beautify my Wikidata applications to show some images. I know this is more of a general MediaWiki question, but it is much more relevant in Wikidata, so I am posting it here first. I guess somebody has already solved this since we have images in various Wikidata-based applications and gadgets.

Re: [Wikidata-l] WikiData Categories
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.

Re: [Wikidata-l] WikiData Categories
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[537] See here for many more options to interrogate Wikidata: http://wdq.wmflabs.org/api_documentation.html Cheers, Magnus On Thu, Jul 3, 2014 at 10:03 AM, Rohan Badlani rohan.badl...@gmail.com wrote: Hi!

Re: [Wikidata-l] WikiData Categories
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!
