In order to describe that the photos participate in the competition we need to be able to link to the correct Wikidata item. Only a handful of those exist, created manually.
From a quick look at https://commons.wikimedia.org/wiki/Category:Wiki_Loves_Monuments_in_Sweden, none of the edition categories are linked to wd items so they can all be created from scratch
e.g. https://www.wikidata.org/wiki/Q98716905
Create a set of items for the Swedish editions, containing
- link to Commons cat (eg https://commons.wikimedia.org/wiki/Category:Wiki_Loves_Monuments_2015_in_Sweden)
- instance of -> recurrent event edition
- part of -> Wiki loves monuments XXXX (year)
- country -> sweden
- part of series -> wiki loves monuments in Sweden (created https://www.wikidata.org/wiki/Q105194463)
- series ordinal
- follows (previous item)
- followed by (next item)
- start time
- end time
- commons category
- organized by -> wmse
