Some Specific Problems in Model Development

• Unbounded specification growth• Semantically duplicate terms, components, and

documents are created• Poor documentation reduces reuse• Classic interoperability problems are revisited• Large-scale harmonization (using a

common/canonical model) is hard to achieve


Content Standards are Bridges

• Design the bridge• Test the design • Build the foundation• Assemble the structure• Test the bridge• Many components are

generic• Many standards are used

Building Process:


Model Development Life Cycle

A guideline for building industrial strength data exchange bridges, that provides

• Detailed analysis of the development process for content standards

• Architecture for implementing that process• Outline of requirements for tools• Roadmap to the standards landscape

Overview of some NIST XML-Related Testing Tools

• XML Schema Validation Tool• XML Instance Validation Tool• Quality of Design Tool• Content Validation and Testing System• XML Schema Naming Assister• Schematron Editor Tool• Classification Assistant (Research)• Semantic-Aware Lookup Assistant (Research)• Semantic Alignment Tool (Research)


XML Schema Validation Tool

• Objective: Ensure that schemas are compatible with a selected set of parsers

• Core Functionality: Validate one or more schemas or schema extensions with multiple selected parsers and schema files stored in a repository

• Status: Prototype available at http://www.nist.gov/msid/validation



XML Instance Validation Tool

• Objective: Ensure that schemas are compatible with a selected set of parsers, a set of sample data, a previous set of sample data (when the schemas have gone through changes)

• Core Functionality: Automatically validate one or more instance files against associated schemas with multiple selected parsers (in batch mode)

• Status: Prototype is available at http://www.nist.gov/msid/validation


Quality of Design (QOD) Tool

• Objective: Ensure that XML schemas conform to a selected set of design practices, e.g., use of common and valid terms, NDR conformance, use of the XML Schema structures that enhance reusability, maintainability, clarity, and interoperability

• Core Functionality: A flexible environment for specifying and executing best practice rules against the schemas

• Status: Beta – Available upon request. Contact Serm Kulvatunyou: [email protected]



Content Validation and Testing System(CVTS)

• Objective: Capture, codify, and execute business rules that are not captured in the XML Schema.

• Core Functionality: Store, publish, and execute business rules for checking instance data for conformance with those rules.

• Status: on-line at http://syseng.nist.gov/b2bTestbed/projects/semanticChecking


XML Schema Naming Assister

• Objective: Ensure that type, element, and attribute names used in schemas are consistent within the schema and conform to ISO 11179 Naming Convention

• Core Functionality: Decompose names into Object Class, Property, and Representation Term tokens, validate them using a table of terms, and suggest alternate names

• Status: Prototype. Available at http://www.nist.gov/msid/Naming_Assister.html


Schematron Editor Tool

• Objective: Assist a user in creating Schematron Rules

• Core Functionality: Create Schematron with little or no knowledge of XPATH/XSLT syntax through expression wizards that allow drag-n-drop elements from an imported XML schema business document

• Status: Prototype – available on Sourceforge site http://www.sf.net/projects/cs-wizard


Summary

• MDLC is a recipe for building robust data exchange specifications

• It drives development of tools and capabilities– Examples include Validation Service and

Quality of Design tools• Maximizes reuse of tools to serve a diverse

collection of customers
