[BYTEIO-WG] ByteIO Interoperability Fiesta

[Karolina Sarnowska]

Hello All,

 

My name is Karolina Sarnowska.  I am a part of Andrew Grimshaw's group at
the University of Virginia.  I have been working with Mark Morgan on getting
Genesis II ready for the Interoperability Fiesta.  I wanted to email
everyone what I just posted on the Wiki regarding some issues with the
documentation.

ByteIO Interoperability Testing Scenarios Document Issues and Corrections


This section lists issues in the ByteIO Interoperability Testing Scenarios
document and presents corrections. The issues are listed in the order that
they appear in the document and reference the specific section they refer
to. 

  _____  


Missing Tags in SOAP Body of Request Message


(4.2) wsrf-rp:GetMultipleResourceProperties operation 

The non-normative example of the elements the ByteIO client adds to the SOAP
body of the request message is missing the <wsrf-rp:ResourceProperty> tag.
The SOAP body should instead contain the following: 

<wsrf-rp:GetMultipleResourceProperties>
    <wsrf-rp:ResourceProperty> rbyteio:Readable </wsrf-rp:ResourceProperty>
    <wsrf-rp:ResourceProperty> rbyteio:Writeable </wsrf-rp:ResourceProperty>
    <wsrf-rp:ResourceProperty> rbyteio:TransferMechanism
</wsrf-rp:ResourceProperty>
</wsrf-rp:GetMultipleResourceProperties> 
  _____  


Incorrect Resource Property Name and Possibly Incorrect Query


(4.3) wsrf-rp:QueryResourceProperties operation 

An incorrect name for the Resource Property is used in the non-normative
example of the elements the ByteIO client adds to the SOAP body of the
request message. The Resource Property queried is called "ModificationTime"
not "ModificationDate". The SOAP body should instead contain the following: 

<wsrf-rp:QueryResourceProperties>
    <wsrf-rp:QueryExpression
Dialect="http://www.w3.org/TR/1999/REC-xpath-19991116">
        /*/rbyteio:ModificationTime
    </wsrf-rp:QueryExpression>
</wsrf-rp:QueryResourceProperties>

It is also unclear whether this example contains the correct query. If the
query does not need to include the namespace, then the query could be
instead "/*/ModificationTime".

Missing Tag in SOAP Body of Response Message


(4.3) wsrf-rp:QueryResourceProperties operation 

The non-normative example of the elements the ByteIO client adds to the SOAP
body of the response message is missing the <rbyteio:ModificationTime> tag.
The SOAP body should instead contain the following: 

<wsrf-rp:QueryResourcePropertiesResponse>
    <rbyteio:~ModificationTime>
      2006-09-11T16:15:33+05:00 
    </rbyteio:ModificationTime>
</wsrf-rp:QueryResourcePropertiesResponse>

Missing Tags in SOAP Body of Request Message


(5.2) wsrf-rp:GetMultipleResourceProperties operation 

The non-normative example of the elements the ByteIO client adds to the SOAP
body of the request message is missing the <wsrf-rp:ResourceProperty> tag.
The SOAP body should instead contain the following: 

<wsrf-rp:GetMultipleResourceProperties>
    <wsrf-rp:ResourceProperty> sbyteio:Seekable </wsrf-rp:ResourceProperty>
    <wsrf-rp:ResourceProperty> sbyteio:TransferMechanism
</wsrf-rp:ResourceProperty>
    <wsrf-rp:ResourceProperty> sbyteio:EndOfStream
</wsrf-rp:ResourceProperty>
</wsrf-rp:GetMultipleResourceProperties> 
  _____  


Possibly Incorrect Query


(5.3) wsrf-rp:QueryResourceProperties operation 

This section incorrectly refers to a modification date query. It should
instead state: In this case, the client wishes to query the resource's
writeable property. 

Mainly, it is unclear whether the non-normative example of the elements the
ByteIO client adds to the SOAP body of the response message contains the
correct query. If the query should include the namespace, then it should be
"/*/sbyteio:Writeable" and the SOAP body should then contain the following: 

<wsrf-rp:QueryResourceProperties>
    <wsrf-rp:QueryExpression
Dialect="http://www.w3.org/TR/1999/REC-xpath-19991116">
        /*/sbyteio:Writeable
    </wsrf-rp:QueryExpression>
</wsrf-rp:QueryResourceProperties>

If the namespace is not required, then querying for "/*/Writeable" if fine.

Missing Tag in SOAP body of Response Message


(5.3) wsrf-rp:QueryResourceProperties operation 

The non-normative example of the elements the ByteIO client adds to the SOAP
body of the response message is missing the <sbyteio:Writeable> tag. The
SOAP body should instead contain the following: 

<wsrf-rp:QueryResourcePropertiesResponse>
    <sbyteio:Writeable>
      true 
    </sbyteio:Writeable>
</wsrf-rp:QueryResourcePropertiesResponse>

Discussion


This section lists questions that need to be answered to resolve ambiguity
in the Interoperability Fiesta documentation. 

  _____  


Queries and Namespaces


If the client wishes to query a resources property, should the query contain
the namespace? Which of the following queries are valid? The sections in
parentheses refer to where the queries appear in the "ByteIO
<http://forge.gridforum.org/sf/wiki/do/createPage/projects.byteio-wg/wiki?pa
geName=ByteIO&referrerPageName=HomePage>  Interoperability Testing
Scenarios" document. 

*	"/*/sbyteio:Writeable" vs. "/*/Writeable" (Section 5.3) 
*	"/*/rbyteio:ModificationTime" vs. "/*/ModificationTime" (Section
4.3)
