| + !!A Syntax for Semantic Annotations |
| + |
| + Here is the current grammar for semantic annotation expressions. Note that parenthesis are special symbols used to define the grammar, e.g., {{( ... )*}} means zero or more, {{( ... )+}} means one or more, and {{( ... )?}} means zero or one. |
| + |
| + |
| + {{{ |
| + [1] AnnotationGroup ::= ( Annotation )+ |
| + |
| + [2] Annotation ::= ItemExp "==>" OntExp |
| + |
| + [3] ItemExp ::= "/" ItemPath | |
| + "name(" 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 )? | |
| + "#" IndividualName ( OntPath )? |
| + |
| + |
| + [9] OntPath ::= "." RoleName ( "#" ConceptName )? ( Var )? ( OntPath )? | |
| + "." RoleName ( "#" IndividualName )? ( OntPath )? |
| + }}} |
| + |
| + The terminal symbols consist of ConceptName, IndividualName, RoleName, and VarName denoting ontology concept identifiers, ontology individual identifiers, ontology role names, and variable names, respectively. |

| + __The Semantics of Semantic Annotations__ |

| + |
| + ## Need to define the scope of of variables within an annotation group |
| + ## Need to determine what having the same variable on the right and left sides means. |
