[ubl] Position Paper: Modularity, Namespaces and Versioning version 3

["Burcham, Bill" <Bill_Burcham@stercomm.com>]

Please find attached version 3 of the Naming and Design Rules Subcommittee Position Paper on Modularity, Namespaces and Versioning.

 

Changes from version 2:

• Added options and recommendation on Namespace identification (OASIS URN namespace versus "namespace name = namespace location")
• Added recommendation on schemaLocation
• In section 7.3 Option 3: Core Plus "Functional" Namespaces, I filled in the table of namespace names for each of the namespaces we've identified thus far.

Pleas find also attached, a .zip file contianing a nascent example.  It consists of tiny schemas for (the XSD realization of) the Core Components CCT's (cc-core-component-types.xsd), a UBL core (core.xsd), a UBL order schema module (order.xsd), a schema defining the UBL order message element (order-message.xsd) and a minimal document instance (Order-1.xsd).

 

Some notes on the example:

• While some of the type and tag names may remind you of UBL type and tag names, the resemblance is purely coincidental.  We need to keep the example short.
• The example is not yet mentioned in the position paper itself.  Next steps are to mention it from the position paper and also to annotate the XML documents themselves so as to make the somewhat self-describing.
• For the example to be truly worthwhile, we'll have to add: invoice schema modules and document instance.  Also we'll need to show an example of a root schema comprised of more than one schema module.

That's all.  See you in Barcelona!
