    <event:abstract><![CDATA[The standards underlying the Semantic Web -- Resource Description
Framework (RDF) and Web Ontology Language (OWL) -- show great
promise in addressing some of the basic problems in earth science
metadata. They provide a framework for explicitly describing the
data models implicit in programs that display and manipulate
data. They also provide a framework where multiple metadata
standards can be described. Most importantly, these data models
and metadata standards can be interrelated, a key step in
creating interoperability. As a exercise in understanding how
this framework might be used, we have created an RDF expression
of the datasets and some of the metadata in the IRI/LDEO Climate
Data Library. This includes concepts like datasets, units,
dependent variables, and independent variables. We have also
created an RDF expression of a taxonomy that forms the basis of a
earth data search interface. These concepts include location,
time, quantity, author, and institution. A series of inference
engines are then used to infer the connections between
data-oriented concepts of the data library to the distinctly
different conceptual framework of the data search.
<p>
We would also like to use this RDF framework to gather and
operate on dataset metadata. The goal is to interoperate between
metadata conventions that are attached to data as they travel in
different formats and are processed by different software. One
could also envision a processing framework that records the
connections between processed data, their source data, and their
processing filters that could be used both to reapply the
processing and document the results. ]]></event:abstract>
