Welcome to the ATLAS Metadata Interface!

This page gives access to two ATLAS tools.
Acces is restricted to members of the ATLAS collaboration

The Tag Collector for ATLAS software release management.
The AMI Dataset Search of ATLAS real and simulated data.

An overview of all the datasets catalogued in AMI.
The simplest way of searching is by dataset name (fast) or keyword (longer, because many fields are searched). This page also acceses the configuration tag interpretation and comparaison.
The advanced search lets you set search criteria on some selected fields. N.B. By default AMI hides datasets which are deleted or known to be bad, this can be disabled when you use the advanced search.
Once you get your results, you can refine them, either by using the selection functions attached to the columns of your result set, or by going to the powerful "Refine Query " interface. If you are new to databases and SQL, we advise you to work through the tutorial before using the "Refine Query" functions. We can also provide bookmarks to complex queries on demand.
