Meta-data for the link itself

Would there be any possibility to have meta-data for the link itself?
That could lead the way for richer queries.

What kind of metadata, and how would you use it?

There is an old feature request for link types:

Meta-data like a node for an enterprise having multiple links with separate sub-nodes for various incidents that enterprise might have been engaging-in while in business.

Then, one of the query add-ons could be used to query for all enterprises having had for similar incidents.

A possible option now would be to use properties. Properties can contain links, if the value is only a link (if it’s text with a link in it, the link won’t work).

At the moment, the links only symbolize a connection, but fail to express “why”.
If a meaning could be added to the link itself, the whole graph would become richer, even yielding smarter results with queries (which are technically a “what-if” activity).
