Seminar Title: Sense and Sensibility: Adding meaning to metadata
for manageable middleware
Abstract
It is a truth universally acknowledged that a grid application in
possession of good middleware, must be in want of meaningful metadata.
We have seen a variety of projects and programmes of activity that
have promoted systematic approaches to describing, linking and
sharing metadata, particularly through the use of community-wide
terminologies or ontologies. Life Sciences have led the way. The
founding of the USA’s National Centre for BioMedical Ontology
(
http://www.bioontology.org <http://www.bioontology.org/>) is an
example. The Semantic Web has given distributed information
management a technical impetus, and once again the Life Sciences
are pioneers. Meanwhile, the Semantic Grid initiative attempts to
marry the two technical efforts of Grid Middleware and Web-wide
Information Management to generally support better metadata (and
data) management for Science applications and the infrastructure
that underpins them. Again, early examples such as myGrid are found
in the Life Sciences. Recent work on a Semantic Open Grid Service
Architecture (S-OGSA) lays the foundation for a systematic yet
lightweight approach to deploying semantics into new and legacy
Grid middleware.
In this talk I will share my experiences of applying Semantic Web
and ontology based approaches to represent and classify metadata
and discuss the Semantic Grid using the S-OGSA as an illustration.
I’ll also take the opportunity to voice some concerns and raise
some challenges that we have to overcome, not many of which are
technical.
