On behalf of the Semantic Annotations of WSDL Working Group I wish to
comment that
http://www.w3.org/TR/2006/WD-wsdl20-rdf-20060518/#genericext
[[
extension attributes are represented as instances of the class
ExtensionAttribute, which in turn have a name (property attributeName
pointing to a QName) and a value (property rdf:value pointing to a
literal containing the attribute value).
]]
loses the namespace and xml:base information needed for resolution of
QNames and relative URIs in the attribute value, as well as xml:lang
assignments which may be necessary for interpreting strings. I propose
the following strawman text (not endorsed by SAWSDLWG):
[[
Each extension attribute is represented as an XML literal containing a
canonicalised representation of the entire extension XML attribute,
placed in an element with the namespace prefix
{http://www.w3.org/2006/07/quotedXML#} and the local name
{attrContainer}. For example, an attribute sawsdl:modelReference on an
Interface component could be serialized as:
+-------------------------------------------------------------------------+
|<iface7> rdf:type wsdf:InterfaceOperation . |
|<iface7> wsdl:extensionAttribute |
| "<quote:attrContainer xml:base="http://example.org/books/search/" |
| xmlns:wsdl="..." xmlns:sawsdl="..." |
| xmlns:wsdf="http://www.w3.org/2006/07/quotedXML#" xmlns:foo="..."|
| sawsdl:modelReference="../temrs#BookSearch"/>"^^rdf:XMLLiteral |
+-------------------------------------------------------------------------+
]]
See <http://www.w3.org/mid/20060707010138.GD14372@w3.org> for more
discussion of this.
