image that visualizes an ancient monument) is shown.

The Kringla interface allows (logged in) users to create links between both internal (SOCH objects) and external data sources
(Wikipedia, Wikimedia Commons, Libris, Europeana). These links are stored in a UGC database.
Platsr has it’s own API. If a user links a Platsr object/story to a Kringla object (actually K-samsök/SOCH) it is shown in Kringla. At the
moment a user can’t create a link to Platsr in Kringla.

Data from these UGC links are presented in the Kringla interface through the UGC database own API. In addition, we also
”harvest” articles and images from Wikipedia and Wikiemdia Commons which contains K-samsök/SOCH persistent URI
which is also showed in Kringla. Among other things all the photos from the Wiki Loves Monuments contest.
