Hi pywikibot experts,

How can I create new properties via pywikibot? (I'm trying to do it via bot, because I'm doing some experiments on a dedicated wikibase installation with - possibly - hundreds of properties to be created... and Pywikibot would certainly be my favorite tool!)

In case I have, instead, to directly wrap the action "wbeditentity" from mediawiki API ( https://www.wikidata.org/w/api.php?action=help&modules=wbeditentity ), are there some Python examples?

And, in case I have to use the php script "importProperties.php" ( https://github.com/JeroenDeDauw/Wikibase/blob/master/repo/maintenance/importProperties.php ), how can I manage properties more complex than the ones contained in the example ( https://github.com/JeroenDeDauw/Wikibase/blob/master/repo/maintenance/en-elements-properties.csv )?


Using pywikibot, I'm able to MODIFY existing properties with instructions like the following ones (which let me generate the object-content in one shot via json ... as I need):

In [1]: import pywikibot ; site = pywikibot.Site() ; repo = site.data_repository()
In [2]: property_page = pywikibot.PropertyPage(repo, u"P2")
In [3]: myjson = {u'descriptions': {u'en': {u'language': u'en', u'value': u'invented description'}}, u'labels': {u'en': {u'language': u'en', u'value': u'test property'}}}
In [4]: property_page.editEntity(myjson)

...but I cannot CREATE new properties (instantiating a PropertyPage object), because pywikibot asks for the identifier of an existing instance:

In [11]: p_page = pywikibot.PropertyPage(repo)
---------------------------------------------------------------------------
InvalidTitle                              Traceback (most recent call last)
<ipython-input-11-e72b812b8cd3> in <module>()
----> 1 p_page = pywikibot.PropertyPage(repo)

/home/user/src/pywikibot_repo/pywikibot/page.pyc in __init__(self, source, title)
   4027         if not title or not self.id.startswith('P'):
   4028             raise pywikibot.InvalidTitle(
-> 4029                 u"'%s' is not an property page title" % title)
   4030         Property.__init__(self, source, self.id)
   4031 

InvalidTitle: '' is not an property page title

In [12]:

In fact, as I understand, in the source code of the "WikibasePage" class, I see that
while for the Item type, a "Special case for empty item" is mentioned ( https://github.com/wikimedia/pywikibot-core/blob/master/pywikibot/page.py#L3760 )

        # Special case for empty item.
        if title is None or title == '-1':
            super(ItemPage, self).__init__(site, u'-1', ns=ns)
            assert self.id == '-1'
            return

...for the Property type, instead, an empty object is NOT allowed ( https://github.com/wikimedia/pywikibot-core/blob/master/pywikibot/page.py#L4168 )

        if not title or not self.id.startswith('P'):
            raise pywikibot.InvalidTitle(
                u"'%s' is not an property page title" % title)
        Property.__init__(self, source, self.id)


Thanks a lot for your attention!
