W3C XML Schema expression patterns

There are four well-knows known W3C XML Schema design expression patterns. They are:

• Russian Doll

• Garden of Eden

• Salami Slice

• Venetian Blind

These The names of these patterns are referenced used in this document. Useful resources for understanding them the patterns include:

OAGi manually maintained OAGIS versions through version 10.6. last manually-maintained version. . Version 10.6 was a result of Mike Rowell, OAGi’s former Chief Architect, manually updating XSD files on his file system, running scripts locally, zipping content, etc.

OAGIS 10.6 was/is offered in four release packages (“editions”):

• Enterprise (included all below)

• Platform (Garden of Eden patternincluded all below)

• Standalone Global (Venetian Blind pattern)

• Standalone Local (Russian Doll pattern)

• Standalone Local Groups

OAGIS 10.7 and later

Beginning with OAGIS 10.7, OAGi began maintaining OAGIS with Score for version 10.7. OAGi ceased to advertise availability of any XML Schema expressions of OAGIS while quietly making the Platform platform model (Garden of Eden) and Standalone (pattern ) editions available to members on request.

1. Model subset: What part of the model needs to be expressed?

   1. All

   2. All except… (e.g., all except supplementary components)

   3. A root component (e.g., BOM)

   4. A set of root components (e.g., BOM, ProcessPurchaseOrder, NotifyShipment)

   5. All components with a specified tag (e.g., noun)

2. Expression type: What is the expression type? (Is there a better name for this other than “expression type”?)

   1. W3C XML Schema

   2. JSON Schema

   3. XMI

   4. Documentation

   5. OAS? (Jim doesn’t think this makes sense)

   6. OWL?

   7. RDF Schema?

3. Pattern: For some expression types, what is the pattern (e.g., Garden of Eden)expression pattern?

4. File system structure: For some expression types, what is the file/folder naming conventions and structure?

5. Internal file organization: For some expression types, how content is organized within files. ? (eE.g., Within within W3C XML schemas Schemas list element declarations first in alphabetical order followed by type definitions in alphabetical order.)?
