The Model Development Life Cycle

To support the validation of content standards, such as depicted in XML Schemas, we have defined a process known as the Model Development Life Cycle. Our experience has shown that this process is a common process used by people developing content standards supporting data exchange. The process is independent of how the exchange is physically manifested, e.g., whether they use XML or some other means of data sharing. The process seems to be consistently followed whether the project explicitly intends to follow it or not. By recognizing the process up front, projects are able to streamline thier efforts and thus save time and aggravation, speed up the delivery of the content standard, and improve the overall quality of the final result.

The Model Development Life Cycle is described in detail in the following reports:

This website provides tools to support many of the steps in the Model Development Life Cycle.
