Hoi,
When an external source is about the same subject as an item, "exact match" is implicit. This property is only to be used with internal items of Wikidata.

I do object for the use of "exact match" with external sources because it implies that Wikidata agrees with all its content, the statements and that is something we should never do.
Thanks,

I am about to propose much more widespread use of Property:P2888 "exact match" for linking from a wikidata item to a URI that should resolve to linked data about the same concept from another semantic web resource.   (amongst the biomedical items that our team works with)

Is there any other pattern that the community here is using to do this that we should be following?  

thanks
Ben
