NAME
       Catmandu::Importer::Wikidata - Import from Wikidata


VERSION
       version 0.06


SYNOPSIS
           catmandu convert Wikidata --ids Q1,P227
           catmandu convert Wikidata --site dewiki --title Wahnsinn

           echo Q1 | catmandu convert Wikidata
           echo Wahnsinn | catmandu convert Wikidata --site dewiki
           echo dewiki:Wahnsinn | catmandu convert Wikidata

           echo Q1 | catmandu convert Wikidata --fix 'retain_field("labels")'


DESCRIPTION
       This Catmandu::Importer queries Wikidata for entities, given by their Wikidata identifier ("Q...",
       "P...") or by a title in some know Wikidata site, such as the English Wikipedia ("enwiki"). The entities
       are either specified as options ("ids", "site", and/pr "title") or as line-separated input values. By
       default, the raw JSON structure of each Wikidata entity is returned one by one. Entities not found are
       returned with the "missing" property set to 1 like this:

           { "id": "Q7", "missing": "1" }

       To further process the JSON structure Catmandu::Wikidata contains several Catmandu fixes, e.g. to only
       retain a selected language.


CONFIGURATION
       This importer extends Catmandu::Importer::getJSON, so it can be configured with options "agent",
       "timeout", "headers", "proxy", and "dry". Additional options include:

       api Wikidata API base URL. Default is "http://www.wikidata.org/w/api.php".

       ids A list of Wikidata entitiy/property ids, such as "Q42" and "P19". Use comma, vertical bar, or space
           as separator. Read from input stream if no ids, nor titles are specified.

       site
           Wiki site key for referring to Wikidata entities by title. Default is "enwiki" for English Wikipedia.
           A list of supported site keys can be queried as part of
           <https://www.wikidata.org/w/api.php?action=paraminfo&modules=wbgetentities> (unless
           <https://bugzilla.wikimedia.org/show_bug.cgi?id=58200> is fixed).

       title
           Title of a page for referring to Wikidata entities. A title is only unique within a selected "site".
           One can also prepend the site key to a title separated by colon, e.g. "enwiki:anarchy" for the entity
           that is titled "anarchy" in the English Wikipedia. Read from input stream if no titles, nor ids are
           specified.
