Summary, in English
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
indexing services for for example brokering during jobsubmission,
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 article we will describe experiences with these
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 Smart
Indexing Service which should deal with the shortcomings
described. Such an indexing service is being designed at
the moment.
