Abstract:
Extensible Markup Language (XML) Schema
documents (XSD) play an important role in software
development process and need to be qualified with
software qualities. A good quality design of XSD
increases software productivity and minimize
development time. In this respect, there are many
qualities: maintainability, reusability,
understandability, extensibility and so on. Among
these qualities, this paper focuses on two qualities:
extensible and reusable qualities and proposes two
metrics to measure these qualities of schema
documents based on Entropy method. Moreover, due
to the defined maximum and minimum values for
each quality metric, the proposed metrics can
measure the specified quality. Therefore, the metrics
can provide valuable information for improving the
quality of XML based systems. The usefulness of the
present metrics is empirically proved through actual
test cases.
