--------------------------------------

comments based on F2F meeting day 1:

1. ATOM REST Binding & inheritance

ATOM REST Binding must behave the same when accessing the artifact type - it should return either instances of given type, or instances of all types in the tree.
See section 2.3.5.3 Retrieving Repository Artifacts of Atom Binding specification - it does not define such behavior.

2. Inheritance Query Proposal

Changes
   * query on type will return instances of all types in the tree
example:

/s-ramp/core/XmlDocument


   * to query for instances of exact type only (i.e., not subtypes) the s-ramp:exactlyClassifiedByAnyOf() function can be used. Based on ATOM Binding specification section 2.3.1, the artifact is classified by the type on atom:entry. Based on Foundation spec, section 2.3.1. every artifact type instance has classifiedBy property. 

We must define classification schema which: a) defines the type model of all artifact types - e.g. OWL of URI http://s-ramp.com/artifacTypes; b) is automatically set on instances.

example:
/s-ramp/core/XmlDocument[ s-ramp:exactlyClassifiedByAnyOf(.,'http://s-ramp.com/artifactTypes#WsdlDocument') ]
