Hi guys,

I'm wondering how to add references that have multiple parts. Take for example https://www.wikidata.org/wiki/Q76 (Barack Obama). The third reference of date of birth has two parts:

• "stated in" -> "Integrated Authority File"
• "date retrieved" -> "9 April 2014"

Currently a reference in our implementation is a special claim [1]. I'm pretty sure the left hand side of a claim is always one property (for example "date of birth"), with references this can be multiple (for example "stated in" and "date retrieved"). Am I missing something or should we change our implementation?

Claim.sources is a list of lists of references:

...

...

i=pywikibot.ItemPage(d, 'Q76') i.get() i.claims['P21'][0].sources

[OrderedDict([(u'P143', [<pywikibot.page.Claim instance at 0x10fb0f170>])]), OrderedDict([(u'P248', [<pywikibot.page.Claim instance at 0x10fb0f290>]), (u'P813', [<pywikibot.page.Claim instance at 0x10fb0f440>])]), OrderedDict([(u'P248', [<pywikibot.page.Claim instance at 0x10fb0f4d0>])])]

...

...

i.claims['P21'][0].sources[1]

OrderedDict([(u'P248', [<pywikibot.page.Claim instance at 0x10fb0f290>]), (u'P813', [<pywikibot.page.Claim instance at 0x10fb0f440>])])

We could probably improve our implementation by having a ReferenceList object or something.
