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.
