Anyone seeing the variety and disconnectedness of the languages or
notations, vertical applications and Subject Matters relating to ontologies is
likely to be confused and one of the purposes over next two days could perhaps address
and weave an integration and interoperation thread!
- Could we think of a possible
overarching ontology or standard (one could argue for both
threads in parallel)?
- We know about the metamodel in
many tools where ER diagrams clarify simple relationships.
- Is there a similar scope for
Ontology based metamodels, the basic element if one goes to RDF approach
would be a triple, for MOF there could be a UML thing / class, etc.
- Then one would see how well this
metamodel captures at least upper level elements of predicate calculus (http://en.wikipedia.org/wiki/First-order_logic)
and also practically develops important use cases of relationships that
are universal. Can the metamodel describe various standards?
- If we can agree on essentials of
such metamodel or the approach to consensus from multidisciplinary
approaches to the metamodel, we can map existing and planned standards
relating to semantics, web and SOA, vertical disciplines (e.g. biology and
its sub disciplines) and see where there are large gaps and analyze
whether it is cost effective to bridge those gaps based on demand or value
to research, business, the government regulation or information sharing
and have a sense of the standards space. To some of us who have been
working on standards and see that even the known methodologies and Standards
Development Organizations (SDOs) have limits of scope and thus overall
integration among various standards (and the spaces covered by SDOs) could
be assisted by such an overview metamodel. How many of IT, Business, and
Knowledge Based as well as semantic standards would enter such a metamodel
could also be addressed.
- Also going forward, for
ontologies to be able to semantically connect themselves, e.g. in biology
(a tall order example!) at least some interoperation standards ought to be
followed by ontologies. For example ODM attempts such a scenario (UML,
OWL, CL) at least but the pace at which different *_ML languages and standards
are being developed (and some even for the semantics), the development
time and resource constraints make it a long time target to achieve? We
need to therefore often de-scope and manage incremental progress while not
losing the canvas on which different SDOs have to interoperate! Can this Summit address priority
areas to SDOs for integration or interoperations among standards? Can
ontology based metamodels help such efforts?
Thanks.
