OSLC Core changes made since latest CSD and CSDPR publication

Here are the changes we have made to the
specification and related documents, or are proposing to make for our upcoming
CS publication:

Changes already made since CSPRD:

* core-vocab.html - fixed minor typos
in description of archived resources
* oslc-core.html - added a section recommending
stable URIs for resource shapes for use in OSLC specifications
* resource-shape.html - updated the
local bibliography with missing reference
* CommonProperties-shape.ttl - fixed
misspelled oslc:ResourceShape
* ResourceShapes-shape.ttl - Added missing
oslc:range rdfs:Class for describes property.
* core-vocab.ttl - removed rdfs:isDefinedBy
and rdfs:seeAlso from the ontology definition, and changed all rdfs:inDefinedBy
to use the oslc: prefix instead of the URI.
* link-guidance.html - provided example
for inverse properties, expanded section on duplicate triples, expanded
discussion of reification of triples, changed antipattern for dealing with
inline values to use of blank nodes 

Proposed non-material changes to
be included in CS:

* Issue
81: add rdf:langString to the
list of types in Resource Shapes, section Literal Value Types

* Issue
25: In Resource Shapes, section
Literal Value Types: note that unless otherwise specified, OSLC Core treats
rdf:langString and xsd:String the same. Note however SPARQL does not. SHACL
introduces sh:text that is the union of xsd:string and rdf:langString to
formally address this issue. SPARQL rules:
If the literal is a typed literal, return the datatype
IRI.
If the literal is a simple literal, return xsd:string
If the literal is literal with a language tag, return
rdf:langString
SPARQL 1.1 defines the result of DATATYPEapplied to a literal with a language tag to be rdf:langString.

*Issue 83, Change oslc:allowedValues
from oslc:Reference, to oslc:Either to allow inlined content. Other possible
oslc:References that could possibly be changed to oslc:Either (entries
marked with X are unlikely to be changed):
  * X Comment inReplyTo
  * X Resource type
  * X Resource serviceProvider
  * X Resource instanceShape
  * X Compact icon
  * X CreationFactory creation,
resourceShape, resourceType, usage
  * X Dialog resourceType, resourceShape,
usage
  * X Discussion discussionAbout
  * X OAuthConfiguration oauhtRequestTokenURI,
authroiztionURI, oauthAccessTokenURI
  * X Publisher icon
  * X Preview document
  * X QueryCapability queryBase,
resourceShape, resourceType, usage
  * X ResourceShape describes,
occurs, range, representation, valueShape, valueType
  * ResourceShape allowedValues,
propertyDefinition, 
  * X Service domain, usage
  * X ServiceProvider details,

  * X ServiceProviderCatalog domain

* Issue
84: add two common properties
oslc:error and dcterms:references and add three properties to oslc:Error:
created, references, identifier. 

* Add all these changes to OSLC Core
specifications, Appendix ?. Change History.

Deferred:

* Inclusion of TRS specification into
OSLC Core 3.0, this will be done in a subsequent OSLC Core release, perhaps
early next year.
