Description
The NorduGrid middleware, ARC, has integrated support for querying and
registering to Data Indexing services such as the Globus Replica Catalog
and Globus Replica Location Server. This support allows one to use these
Data Indexing services for for example brokering during job-submission,
automatic registration of files and many other things. This
integrated support is complemented by a set of command-line tools for
registering to and querying these Data Indexing services.
In this talk we will describe experiences with these Data Indexing
services both from a daily work point of view and in production
environments such as the Atlas Data-Challenges 1 and 2. We will describe
the advantages of such Data Indexing services as well as their
shortcomings. Finally we will present a proposal for an extended Data
Indexing service which should deal with the shortcomings described. The
development of such a Data Indexing service is being planned at the
moment.
