RE: SparqlQuery-1G missing schemaLocation

In practice I don't see much difference between augmenting a testcase
with a schemaLocation attribute, or augmenting it with a catalog file.
Either way seems to be a bit intrusive.  This testcase is riddled with
schemaLocation attributes - just missing the one I was looking for.
Let's ask the DAWG why it was omitted in this one instance.

 

FWIW, as this testcase involves multiple levels of schema import, I'm
unlikely to ever pass this test even after implementing support for
parsing the HTTP binding namespace.

Youenn/Jonathan, 

The sparql test case was taken from their spec and is a "real world"
example. We shouldn't modify the test cases just to make our processors
pass. We need to fix our processors. 

Recall that I did include an XML catalog for another test case case, but
got "shot down". I think we need to revisit this policy. I suggest we
include realistic test cases that omit schemaLocation or WSDL location
attributes, but provide an XML catalog for these cases. We don't require
any processor to support a specific mechanism for locating resources,
but we can provide the XML catalogs and let the processors use that
information however they want, possibly with human intervention to
tranlate the XML catalog into a format that the processor can handle. 

I suggest the following for test cases that omit location attributes: 
1. Provide an XML catalog in the OASIS standard format 
2. Provide related test case with the location attributes included

Re: SparqlQuery-1G missing schemaLocation

 

 

 




I donwloaded the schema document and added schemaLocation information in

the wsdls & schemas wherever needed.
Please find in attachment all the schemas that I needed to process the 
document correctly.
I do not remember where I get the main schema (result2.xsd) however.
It may be safer to check with the sparql guys.

Youenn

  See http://www.w3.org/XML/1998/namespace.html and

   This schema document describes the XML namespace, in a form
   suitable for import by other schema documents.  

   Note that local names in this namespace are intended to be defined
   only by the World Wide Web Consortium or its subgroups.  The
   following names are currently defined in this namespace and should
   not be used with conflicting semantics by any Working Group,
   specification, or document instance:

   base (as an attribute name): denotes an attribute whose value
        provides a URI to be used as the base for interpreting any
        relative URIs in the scope of the element on which it
        appears; its value is inherited.  This name is reserved
        by virtue of its definition in the XML Base specification.

   id   (as an attribute name): denotes an attribute whose value
        should be interpreted as if declared to be of type ID.
        The xml:id specification is not yet a W3C Recommendation,
        but this attribute is included here to facilitate
experimentation
        with the mechanisms it proposes.  Note that it is _not_ included
        in the specialAttrs attribute group.

   lang (as an attribute name): denotes an attribute whose value
        is a language code for the natural language of the content of
        any element; its value is inherited.  This name is reserved
        by virtue of its definition in the XML specification.
 
   space (as an attribute name): denotes an attribute whose
        value is a keyword indicating what whitespace processing
        discipline is intended for the content of the element; its
        value is inherited.  This name is reserved by virtue of its
        definition in the XML specification.

   Father (in any context at all): denotes Jon Bosak, the chair of 
        the original XML Working Group.  This name is reserved by 
        the following decision of the W3C XML Plenary and 
        XML Coordination groups:

            In appreciation for his vision, leadership and dedication
            the W3C XML Plenary on this 10th day of February, 2000
            reserves for Jon Bosak in perpetuity the XML name

<xs:annotation>
 <xs:documentation>This schema defines attributes and an attribute group
       suitable for use by
       schemas wishing to allow xml:base, xml:lang, xml:space or xml:id
       attributes on elements they define.

       To enable this, such a schema must import this schema
       for the XML namespace, e.g. as follows:
       &lt;schema . . .>
        . . .
        &lt;import namespace="http://www.w3.org/XML/1998/namespace"
                   schemaLocation="http://www.w3.org/2001/xml.xsd"/>

       Subsequently, qualified reference to any of the attributes
       or the group defined below will have the desired effect, e.g.

       &lt;type . . .>
        . . .
        &lt;attributeGroup ref="xml:specialAttrs"/>

        will define a type which will schema-validate an instance
        element with any of those attributes</xs:documentation>

<xs:annotation>
 <xs:documentation>In keeping with the XML Schema WG's standard

  The schema document at that URI may however change in the future,
  in order to remain compatible with the latest version of XML Schema
  itself, or with the XML namespace itself.  In other words, if the XML
