Ontology to model access control

Dear all,

to guide the integration of data into DBpedia+ effectively, we are 
working on a new release of DataID, i.e. it's ontology [1,2] and an 
implementation of a repository to manage metadata effectively and 
distribute it to different other venues like datahub.io via push.

we are looking for an ontology that allows us to express access rights 
to model the following roles:

for metadata editing: Guest, Creator, Maintainer, Contributor
for datasets: Guest, Creator, Maintainer, Contributor, Contact, Publisher

We are thinking about copying some ideas from here: 
https://hal-unice.archives-ouvertes.fr/hal-01202126/document
e.g. to have something like:

[] a dataid:AuthorityEntityContext ;
    dataid:authorizedFor :x ; # this is a prov:Entity (either a DataId, 
a Dataset or a distribution)
    dataid:authorityAgentRole dataid:Maintainer ;
    dataid:authorizedAgent  [ (insert FOAF here) ] .


Any ideas or pointers?
A detailed analysis of the problem has been published by our ALIGNED[4] 
partner SWC [3]

All the best,
Sebastian and Markus
