Well, we do use import for the test wikis when we rebuild the wiki and for
sample data. It involves having all the referenced properties and I think
one of the rebuild scripts for the secondary data.
For importing items in the special page, the exports should have the
content type. If the content type is an entity, then Wikibase should
disallow the import.
If it's a wiki that does not have wikibase installed, then it's an
"unknown" content type and not sure MediaWiki should be allowing import of
unknown content via Special:Import :)
Cheers,
Katie

Yeah. Thanks Katie for investigating. This is much less of a pressing
issue than I initially thought.
On big problem are IDs. What to do if the
item's ID is taken? Also, all
the
properties used by the item are going to have
wrong IDs...
Yes. In the item in question you could also see statements with
completely missing properties but existing values (presumably because
the property didn't exist) and statements where the datatype of
property and value didn't match (presumably those where the property
ID exists but is taken by a completely different property).
This is all very messy and I think we should declare this wontfix
until someone comes up with an actual real-world case where it's
needed.
Cheers
Lydia
