Organization Conventions
Best practice for extensibility and reusability
of the schema Local type should not be used.
Globally defined types allow reuse while the
local types do not.

• OAGIS Best Practices
• KIEC XML Guideline
• UBL Naming and Design rules
• ASC X12 Reference Model for XML Design
• And more

OrganizationConventions
Developer

• It helps the developer to make XML schema
  consistent.

8
XML Schema Design Quality Testing

• Testing system requirements
• Several organizational conventions should be
  satisfied.
• Distributed work should be enabled.
• Common conventions should be shared or reused.

• Rule-based Expert System
• Decision making system based on knowledge of rules

Rule-based Expert System

• JESS (Java Expert System Shell script) for
• JAVA Web implementation

Objectives
To propose the rule-based expert system to ensure
the quality of XML Schema design

1. To show the system framework

1. To encode testing rules from organization
   conventions

1. To translate XML schemas into facts

1. To implement the prototype

(assert laboratory (University POSTECH)

Template Definition

deftemplate attribute (slot id) (slot name)
(slot value) deftemplate relation (slot type
(default attribute)) (slot parent) (slot child)

Fact Transformation

• XML Schema to JESS Fact

complextype
name (Dep)
XSLT
Templates Definition (deftemplate element
(slot id) (slot name)) (deftemplate attribute
(slot id) (slot name) (slot value)) (deftemplate
relation (slot type (default attribute)) (slot
parent) (slot child)) (deftemplate text (slot id)
(slot value)) Fact Assertion (assert (element
(id N000001) (name xsdelement))) (assert
(relation (type attribute) (parent N000001)
(child N000002))) (assert (attribute (id N000002)
(name name) (value Dep)) (assert (relation (type
element) (parent N000001) (child
N000003))) (assert (element (id N000003) (name
xsdcomplexType))
17
Rule Encoding

• Organization convention to JESS Rules

The schema must have Lab element as the child
node of Dep element
(defrule laboratory (element (id ?e-id) (name
Dep)) (relation (type element) (parent ?e-id)
(child ?e-id2)) (element (id ?e-id2) (name
Lab)) gt (printout t "Good Schema Design
crlf)) )

Demo Scenario

• OAGI design document
• Check for improper use of local type

• Global element
• To allow it to be referenced and reused

• Scenario
• Find the local type.
• If the local type does not exist, printout This
  schema does not local type.
• If the local type exist, printout This local
  type should not be used for each local type.
