URI Scheme for Specializers

[Eric Sirois <esirois@ca.ibm.com>]

Hello fellow TC members.

As a follow-on to my original note "URI scheme for TC subcommittees " (
http://www.oasis-open.org/archives/dita/200710/msg00000.html) and Jeff
Ogden's follow-up note (
http://www.oasis-open.org/archives/dita/200710/msg00042.html)

I would like to propose the following the amended design pattern that
specializers should use when creating URIs to uniquely identify schema
documents for their DITA XML Schema specializations.  The new design
pattern is as follows:

urn:oasis:names:tc:dita:spec:<specialization-family-name>
:xsd:<filename.xsd>:<version>

The new design patterns allows for a broader use beyond what I had
originally proposed in my note.  The design pattern will help anyone or any
group proposing a new specialization to the TC, not necessarily via
subcommittee, to uniquely identify their specialization or family of schema
documents that belong to a particular specialization.

For example:
URIs would replace any instance where are relative or absolute path URL
would have normally been used in a schema document as a means to identify a
schema document.

<?xml version="1.0" encoding="utf-8"?>
<learningSummary xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
 xsi:noNamespaceSchemaLocation="../schemas/learningSummary.xsd"
 id="learningsummary">

would be

<?xml version="1.0" encoding="utf-8"?>
<learningSummary xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
 xsi:noNamespaceSchemaLocation=
"urn:oasis:names:tc:dita:sc:learning:xsd:learningSummary.xsd:1.0"
 id="learningsummary">

The same would apply to include/redefine/import in the schemas documents

<!--  ================ INFO TYPES =====================  -->
  <xs:include schemaLocation=
"urn:oasis:names:tc:dita:sc:learning:xsd:learningAssessmentGrp.xsd:1.0"/>

Unfortunately, I will not be able to attend the TC meeting tomorrow.  I
will be available until 10AM (EST) to answer any questions you might have.

Kind regards,
Eric
