Here is my summarized version of the proposed
grammar for 'Const' in BLD/FLD
Const ::= '"' UNICODESTRING '"^^' SYMSPACE"
---should be replaced by--->
ANGLEBRACKIRI ::= '<' IRI_REF '>'
STRING ::= '"' UNICODESTRING '"'
CURIE ::= PNAME_LN | PNAME_NS
Const ::= STRING '^^'ANGLEBRACKIRI
| STRING '^^' CURIE
| ANGLEBRACKIRI -> shortcut for rif:iri
| CURIE -> shortcut for rif:iri
| STRING -> shortcut for xsd:string
| NumericLiteral -> shortcut for xsd:integer,
xsd:decimal, xsd:double
| '_' LocalName -> shortcut for rif:local
<!-- | STRING LANGTAG -> shortcut for rif:text -->
This relies on reuse of the following grammar productions defined in
other documents:
PNAME_LN, cf. http://www.w3.org/TR/rdf-sparql-query/#rPNAME_LN
PNAME_NS, cf. http://www.w3.org/TR/rdf-sparql-query/#rPNAME_NS
LANGTAG, cf. http://www.w3.org/TR/rdf-sparql-query/#rLANGTAG
NumericLiteral,
cf. http://www.w3.org/TR/rdf-sparql-query/#rNumericLiteral
IRI_REF, cf. http://www.w3.org/TR/rdf-sparql-query/#rIRI_REF
LocalName,
cf. http://www.w3.org/TR/2006/REC-xml-names11-20060816/#NT-LocalPart
UNICODESTRING, any unicode string where quotes are escaped
and additionally all the other escpape sequences defined in
http://www.w3.org/TR/rdf-sparql-query/#grammarEscapes and
http://www.w3.org/TR/rdf-sparql-query/#codepointEscape
Actions:
- Axel to add xsd:double in DTB as symspace and datatype.
Open Issues:
- relative vs. absolute iri & base iri definition not yet resolved
- prefix definition not yet resolved
- langtag shortcut for the moment not addressed, but probably needs revisit
after this is resolved with the OWL WG.
- another issue: We should remove the sentence:
"The compact URI notation is not part of the RIF-BLD syntax."
from BLD.
