Did not really look for the extent of that one, but see that example:
The is a CC-licensed photo of a PD object − which is fairly common − so there is both aa CC-BY-SA tag and a PD-old-100 one.
(note this is a somehow nice case because license are nested into {{copyright information}} tag which labels what copyright status is for what)
The API returns :
"LicenseUrl": {
"value": "http://creativecommons.org/licenses/by-sa/3.0\n",
"source": "commons-desc-page",
"hidden": ""
},
"LicenseShortName": {
"value": "Public domain",
"source": "commons-desc-page",
"hidden": ""
},
"UsageTerms": {
"value": "Public domain",
"source": "commons-desc-page",
"hidden": ""
},
"Copyrighted": {
"value": "False",
"source": "commons-desc-page",
"hidden": ""
Effectively mixing up both license.
