> However, if you can gently guide people towards those forms that the system can understand,
The following assists editorial cleanup assistance rather than authoring:
Special:Relations and Special:Attributes both give counts of the numbers
in the smw tables, thus on wiki.ontoworld.com:
Is in (2)
Located in (56)
Is located in (67)
(hmm...) That doesn't scale any better or worse than Special:Categories.
Each property in those lists should have an infolink that performs a
SearchTriple for it.
People favor adding a footer to every Attribute: and Relation: page that
gives information about its usage, like the info in Category: pages
(feature request 1505021); MediaWiki doesn't make this easy to implement
as far as I can tell.
