Overview

The XML Schema Quality of Design Tool, also called the QOD Tool, assists in consistently using XML Schema for the specification of information.  Consistent design of XML schemas within an organization or single integration project can reduce the number and the severity of interoperability problems.  In addition, this consistency makes the XML schema easier to extend, understand, implement, and maintain; and, it paves the way for automated testing and mapping. Applying best practices is one way to achieve this design consistency.

The purpose of QOD is to provide a collaborative environment for checking XML schema design quality.  QOD is intended for both people developing guidelines for writing high quality XML schemas and those writing XML schemas.   The system provides a database of guidelines, as well as, tests for checking for adherence to the guidelines.  The guidelines come from a number of sources including documents from a variety of standards organizations.  Users also may add guidelines and tests to the system.

The system may be accessed as an anonymous user or with an account.  As an anonymous or guest user, you may check whether a schema that you are developing or uses meets a set of guidelines in the system. Users with an account may be interested in adding their own rules and making sets of rules available to their communities.

Currently, initial sets of tests exists for the following standards documents.  We welcome feedback and improvements to these tests.
