Abstract:
Individual organisations as well as industry consortia are
currently defining application and domain-specific languages using the
eXtended Markup Language (XML) standard of the World Wide Web
Consortium (W3C). This trend introduces new challenges for version and
configuration management. We show that configuration management for
XML languages is considerably more complicated for an XML Schema
or DTD than it is for traditional software engineering artifacts. In addition
to internal consistency of the language definition, also consistency
between the language and its instance XML documents needs to be preserved
when evolving the language definition. We propose a definition
for compatibility between versions of XML languages that takes this additional
need into account. Compatibility between XML languages in
general is undecidable. We argue that the problem can become tractable
using heuristic methods if the two languages are related in a version history.
We propose to evaluate the method by using different versions of
the Financial products Markup Language (FpML) in whose definition
we participate.
