Abstract: Model differentiation techniques, which provide the
capability to identify mappings and differences between models,
are essential to many model development and management practices.
There has been initial research toward model differentiation
applied to UML diagrams, but differentiation of domain-specific
models has not been explored deeply in the modeling community.
Traditional modeling practice using the UML relies on a single
fixed general-purpose language (i.e., all UML diagrams conform to
a single metamodel). In contrast, Domain-Specific Modeling (DSM)
is an emerging model-driven paradigm in which multiple metamodels
are used to define various modeling languages that represent the
key concepts and abstractions for particular domains. Therefore,
domain-specific models may conform to various metamodels, which
requires model differentiation algorithms be metamodel-independent
and able to apply to multiple domain-specific modeling languages.
This paper presents metamodel-independent algorithms and
associated tools for detecting mappings and differences between
domain-specific models, with facilities for graphical
visualization of the detected differences.
