Another obstacle for the Semantic Web standardization effort relates to the fact that,
despite many industrial companies and consortiums having realized that a explicit
description of semantics of data and domain modeling is necessary for application
integration, they still have used for that purpose their company/consortia-specific
standards or XML language that are inappropriate for global integration. Even realizing
that the Semantic Web is providing really global standards, it is already too
late and too labor- and resource-consuming to transform manually huge amounts of
already modeled metadata from a local to a global standard. One possible solution
would be to design semantic adapters that enable semi-automatic transformation
from company-specific standards to Semantic-Web standards. This motivates the
second objective of the SmartResource Adaptation Stage, which is a design of the
General Adaptation Framework aimed to provide a methodology for designing
adapters from various data formats to RSCDF and back. The pilot version of the
task and its solution are presented as deliverables of the SmartResource project, 4
along with concrete test implementations of the approach of General Adaptation
— adapters for three different samples of heterogeneous resources (device data, expert
interface, Web service). The conceptual picture of General Adaptation Framework
is shown in Figure 4.
