RE: [xml-dev] Data model vocabulary

["Lists DMS" <lists@d-m-s.co.nz>]

Hi William,

Your requirements are to some degree met by MXV, which is a model-driven XML
Vocabulary design solution: 

a) A unified bespoke data model is held as UML class diagrams to take
advantage of UML's visual expressiveness and structured meta data
b) The data model is then transformed into versioned XML schema component
libraries by following the OASIS UBL NDR 2.1 design rules
c) The schema developer then picks the required components from the XML
schema library models to create a XML document schema model that conforms to
the unified data model
d) The document schema model then generates the document schema XSD file,
that conforms to the unified data model and OASIS UBL NDR
More details at http://www.d-m-s.co.nz/serv_xmlschema.htm

Your vocabulary requirements are met as indicated in brackets:
- Must be an XML vocabulary (yes, UML is the master which generates the XML
schema library files)
- Must Support standard XML Schema constraints: data types (yes),
cardinality (yes), etc. (like in UBL, some constraints deliberately
validated by 2nd-pass validation, see
http://www.d-m-s.co.nz/serv_xmlval.htm)
- Should Support XPath validation (assertions) like Schematron, RelaxNG (no,
the data models are validated by scripts, but Schematron may optionally be
used for 2-pass XML instance validation)
- Must be convertible from XML Schema (in principle yes, but conflicts in
source schemas may prevent an automatic schema merge into UML where trees
overlap) / to XML Schema (yes)
- Must support human-readable definitions of every element in various
languages (one language only at this stage).
- Should be extensible to support custom properties for every element (yes,
except the attributes of common basic components are pre-defined as per
OASIS UBL NDR rules and UN/CEFACT data types)
- Desirable: support for modeling graphs, not just trees of data (yes, as
UML classes and interrelationships). 

I hope this helps.
