Description changed from

relations have a direction, the verb of the relation should signify that direction, so we propose to use  hasNode, 
hasService, hasInboundPort, etc.

hierarchy of relations: 

hasNode, hasInboundPort, isSink, 

or do we want to keep with has:

 hasNode, hasInboundPort, <-hasSink--

relations have a direction, the verb of the relation should signify that direction, so we propose to use  hasNode, 
hasService, hasInboundPort, iSource, isSink, etc.

	Comment:	Fine by me too (original proposal was by Jeroen). As for the exact relation between Ports and Links: I wrote a full proposal in artf6550.

Comment:

I think two discussions are mixing here.

Let's focus on the proposal to start each relation type with a verb.

Wether it should be "hasSource" or "isSource" and which direction (from Link to Port or from Port to Link)  for this particular relation is, is a 
separate discussion.

	Comment:	True, but we have used the "sink" relation, which is confusing because it doesn't imply a direction (of the relation).
	Action:	Update

	Comment:	I dont have a strong preference, we have never used 'isSink' in practice so this seems strange to me.
