Physical access to other scientist's data sets or to maps derived from
the data sets, is a good first step, but not sufficient for
effectively using the data for computational analyses. This part of the
project focuses on common data models that can provide data, programs
and metadata in a uniform manner, and has three focii:
-
a data model for
marine geology data that abstracts across cruise formats (Figure 1),
-
an
infrastructure so that metadata for data sets published with different
formats, or buried within data files, can be viewed as if they were all of the
same format, and
-
a distributed infrastructure so that data files and
application output could be viewed as database queries (Figure 2).
The metadata
viewer (2) and the infrastructure for integrating marine geology data and
applications (3) use LeSelect, a framework for accessing heterogeneous
data and programs over internet environments. LeSelect, developed by Eric
Simon and colleagues at the Institut Nationale pour Recherche en
Informatique (INRIA), France, provides an underlying mechanism for
distributed access to files, databases and programs. We extend LeSelect by
providing wrappers that map marine geology data files, metadata and
programs onto commonly recognized names and formats, and clients that
provide a uniform application interface for marine geology.
