Type URL can:
Define a property:
Be queried for the property:
- {{#show: Some page | ?URL}}
- {{#ask: [[Some page]] | ?URL}}
But cannot be queried by property if the URL has an equals sign in it:
- {{#ask: [[URL::https://www.google.com/search?q=semantic+mediawiki]] | ? | ?URL}}
- {{#ask: [[URL::=]] | ? | ?URL | link=none}}
It will produce the incorrect error "Some subquery has no valid condition.".
This was tested in SMW 1.6. I'm not sure if this bug still exists in current development versions (I can't use SMW 1.6.1 because image queries do not work well).
Version: unspecified
