| Abstract |
The long title of the presentation captures the essence of the work
that
Lars has been doing over the summer at the Corporation for National
Research Initiatives (CNRI) for National Cancer Institute's (NCICB/NIH)
caBIG project. The "cancer Biomedical Informatics Grid,",or caBIG, is a
voluntary network or grid connecting individuals and institutions to
enable the sharing of data and tools, creating a World Wide Web of
cancer research. As part of that caBIG project, Argonne has been working
with CNRI to design and implement an Identifier Services Framework
that allows life-science data-objects to be assigned globally unique
and resolvable identifiers (URI/IRIs). The implementation leverages the
Globus Toolkit and CNRI's Handle System, which is a general purpose
distributed information system that provides efficient, extensible,
and secure identifier and resolution services. The Handle System
service implementation had to be modified and adapted in order to meet
caBIG's high requirements to (re-)assign identifiers to 200 million
(re-)generated caBIO-data-objects every two weeks.
In this presentation, Lars will discuss some of caBIG's identifier
requirements and the developed solutions.
