oslc:range property values.

["Jim Amsden" <jamsden@us.ibm.com>]

At the last Core TC meeting I was assigned
the following actions:

1. Weaken the description of range so that it is recommended types, not required types
2. Create an inventory of core object properties that could have a type and propose one
3. Send out an email with this information and get feedback whether this should be included in the spec or not. 

Below are the results. Take a look at
the proposed oslc:range values and see if these are 1) useful and 2) not
over-constraining server implementations or domain usages.

We should schedule a vote on this, and
if adopted I will add the oslc:range values to the property shapes.

1. oslc:range property description:


In the specification body: The object
resource SHOULD be any of the specified oslc:range types, but no inferencing
is intended if the actual target resource is or is not one of these types.
This is very different semantics than rdfs:range which does have inferencing
implications. 

This may already be weak enough.

in the shape file:  "For
object properties, an allowed object resource type." 
Change to: "For object properties,
specifies what the object resource type is expected to be, but that is
not necessarily the case." 

2. Proposed oslc:range values for object
properties:
