Architecture-Driven Modernization Knowledge Discovery Meta-Model (KDM) V1.3.pdf
KDM is defined via Meta-Object Facility (MOF). KDM determines the interchange format via the XML Metadata
Interchange (XMI) by applying the standard MOF to XMI mapping to the KDM MOF model. The interchange format
defined by KDM is called the KDM XMI schema. The KDM XMI schema is provided as the normative part of this
specification.
KDM is a meta-model with a very broad scope that covers a large and diverse set of applications, platforms, and
programming languages. Not all of its capabilities are equally applicable to all platforms, applications, or programming
languages. The primary goal of KDM is to provide the capability to exchange models between tools and thus facilitate
cooperation between tool suppliers to integrate multiple facts about a complex enterprise application, as the complexity
of modern enterprise applications involves multiple platform technologies and programming languages. In order to
achieve interoperability and especially the integration of information about different facets of an enterprise application
from multiple analysis tools, this specification defines several compliance levels thereby increasing the likelihood that
two or more compliant tools will support the same or compatible meta-model subsets. This suggests that the meta-model
should be structured modularly, following the principle of separation of concerns, with the ability to select only those
parts of the meta-model that are of direct interest to a particular tool vendor. Separation of concerns in the design of KDM
is embodied in the concept of KDM domains.
