The flow of linked data information is dependent that systems are coordinated and good controlled change management exists plus changes done need to be visible for the user. Compare [[ https://www.wikidata.org/w/index.php?title=Q6339160&action=history | Wikidata version history ]]

**TODO** Define a change process for errors like this that can track changes needed between more platforms/sources
# Problems I see
# **Text string at [[ https://digitaltmuseum.se/011025171260 | Digital museum Gunnar Wennerberg ]]** not referencing an entity at Digital museum/[[ https://kulturnav.org/ | kulturnav.org ]]
# kulturnav.org is the linked data layer that should address **text strings errors** as Gunnar Wennerberg
# the mentioned object above is from "Värnersborgs museum" that I have not find a dataset for [[ https://kulturnav.org/ | kulturnav.org ]]
# **TODO** [[ https://digitaltmuseum.se/owners/S-VM | tell Värnersborgs museum ]] [[ https://mail.google.com/mail/u/0/?view=cm&fs=1&tf=1&source=mailto&to=vanersborgsmuseum@vgregion.se | email ]] to create a linked data object for Gunnar Wennerberg at [[ https://kulturnav.org/ | kulturnav.org ]]

# on the Europeana html page there is an id and a link to RDF [[ http://kulturarvsdata.se/vbg/object/VM15770 | kulturarvsdata: VM15770]] that should be to a human readable page
