The XML syntax for WRL is originally given through a mapping
in the WRL specification document. This document describes the
XML Schemas for the XML syntax.
The XML syntax set consists of the following documents:
- Identifiers
- IRIs, data values and the like are specified according to
wrl-identifiers.xsd
- Conceptual syntax
-
The main schema for WRL/XML is
wrl-xml-syntax.xsd.
- Logical expression syntax
-
The logical expression syntax uses a number of schemas from
RuleML:
naffolog.xsd
enables the modeling of rules using Lloyd-Topor and includes
negation-as-failure
frame_module.xsd
enables
the frame-style modeling (molecules) of WRL
The namespace of the WRL-specific elements is
"http://www.wsmo.org/wsml/wrl-syntax#". The namespace of the RuleML
elements in the logical expression syntax is
"http://www.ruleml.org/0.89/xsd".
