A grammar for semantic annotations

• Note that parenthesis ( ) are used to define the syntax, e.g., ( ... )* means zero or more, ( ... )+ means one or more, and ( ... )? means zero or one.

 [1]   AnnotationGroup  ::=   ( Annotation )+ 

 [2]   Annotation       ::=   ItemExp ( "," ItemExp )* "==>" OntExp

 [3]   ItemExp          ::=   "/" ItemPath

 [4]   ItemPath         ::=   ElemName ( "[" ItemCntxtExp "]" )*  ( Var )?  |
                              ItemPath "/" ItemPath  | 
                              "*"  | 
                              "."

 [5]   Var              ::=   "{" "$" VarName "}"

 [6]   ItemCntxtExp     ::=   ItemPath  | 
                              ItemPath ValueComp ItemValue

 [7]   ValueComp        ::=   "eq" | "ne" | "lt" | "le" | "gt" | "ge"


 [8]   OntExp           ::=   ConceptName ( Var )? ( OntPath )?


 [9]   OntPath          ::=   "." RoleName ( "#" ConceptName )? ( Var )? ( OntPath )?

• Some simple examples of an XML-ified version:

  <!-- a very simple annotation -->
  <sms:AnnotationGroup object="urn:lsid:...">
    <sms:Annotation>  / ==> AConcept  </sms:Annotation>
  </sms:AnnotationGroup>

  <!-- a simple annotation where a new concept is defined -->
  <sms:AnnotationGroup object="urn:lsid:...">
    <sms:Annotation>  / ==> MyConcept  </sms:Annotation>
    <sms:Where>
      <owl:Class rdf:ID="MyConcept">
        ...
      </owl:Class>
    </sms:Where>
  </sms:AnnotationGroup>

  <!-- a minimilistic port/dataset style annotation -->
  <sms:AnnotationGroup object="urn:lsid:...">
