Re: [xml-dev] RE: Proposal: a building block approach to XML design

[Stephen D Green <stephengreenubl@gmail.com>]

Had a look at XBRL?

 

Personally the complexity of it puts me off the whole idea of reusable building blocks

using just XSD. Better to have the reusable blocks defined outside of the schema set and

some rules to determine how to generate a schema set from the blocks (in the model)

you are using. Interoperability is then achieved at model level and also by having some

deterministic rules for creating the scheme set. This is pertty much the approach on which

OASIS UBL settled for customisations. And with UBL the blocks are the Core Component

library of entities which can be extended. If every domain (books, etc) has a set of entities

in the same shared library of components each implementing the same model spec (e.g.

ISO 15000) and you have a suitable set of rules (e.g. UBL or CEFACT naming and design

rules) to generate a scheme set from your required combined library of entities you should

be able to generate a scheme set for any required combination of domains (books, etc).

It should be good for interoperability between various combinations of domains (even for

various combinations of models and naming and design rules if a common set of core

components is created for all to use - as with the CEFACT Core Component Libraries).
