As a Wikibase Editor, I want to find out more details about different federated properties (scope, constraint definitions, usage examples) so I know how to use them to make statements.
Currently, users would access Special:ListProperties to browse through properties in their local Wikibase. In the federated properties MVP, there will be no local properties.
When a user navigates to the list of properties, they should see an intermediate screen containing a message that they will need to leave the local instance and go to the external Wikidata page (there will be a clickable link to the wikidata.org / remote Wikibase list of properties page, e.g. wikidata.org/wiki/Special:ListProperties).
BDD (displaying the interim page)
Given My wikibase has federated properties enabled
WhenI navigate to Special:ListProperties
Then an interim page is displayed explaining that I must navigate to the source Wiki [see mock]
BDD (accessing the remote list of properties)
Given I have loaded Special:ListProperties with federated properties enabled
WhenI select the link to view the list of properties on the source wiki
Then Special:ListProperties on the source wiki opens according to my default browser behavior
