PROV-ISSUE-406 (delegation-direction): Direction of prov:Delegation is non-intuitive [Ontology]

On product: Ontology

After the rename from prov:Responsibility to prov:Delegation, I believe the PROV-O mapping of actedOnBehalfOf is non-intuitive with regards to the direction.

Consider the graph in 


showing only the qualified relationship. If you read this intuitively, as someone who will find the RDF in the wild - it easily reads the wrong way.

I've discussed some potential solutions on that wiki page:

* Make <code>prov:hadDelegate</code> be the unqualified property and change the direction of <code>prov:Delegation</code>
** Should then be pretty obvious; would not have <code>prov:Agent</code> problem
** ..but wrong direction/term according to DM.. 
*** DM to change actedOnBehalfOf(responsible, delegate) to hadDelegate(delegate, responsible)? 
* Use more specific properties like <code>prov:responsible</code> rather than confusing <code>prov:agent<code> 
** but.. harder to identify the 'special' outgoing link of qualification
* Rename <code>prov:Delegation</code> and <code>prov:qualifiedDelegation</code>
** prov:Delegate ?
** prov:ActedOnBehalfOf  ?
** .. ?
