Query: Towards a Virtual Data Centre for Classics   The paper presents some of our work on integrating datasets in Classics. We
present the results of various projects we had in this domain. The conclusions
from LaQuAT concerned limitations to the approach rather than solutions. The
relational model followed by OGSA-DAI was more effective for resources that
consist primarily of structured data (which we call data-centric) rather than
for largely unstructured text (which we call text-centric), which makes up a
significant component of the datasets we were using. This approach was,
moreover, insufficiently flexible to deal with the semantic issues. The gMan
project, on the other hand, addressed these problems by virtualizing data
resources using full-text indexes, which can then be used to provide different
views onto the collections and services that more closely match the sort of
information organization and retrieval activities found in the humanities, in
an environment that is more interactive, researcher-focused, and
researcher-driven.
