Welcome to the ATLAS Metadata Interface!

The AMI Dataset Search of ATLAS real and simulated data. http,  https

• An overview of all the datasets catalogued in AMI. ( http,  https )
• The simplest way of searching is by dataset name (fast) or keyword (longer, because many fields are searched).( http, https ) links to the dataset search and the configuration tag interpretation
• 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. ( http,  https )
• Interpretation of the dataset configuration tags. ( http,  https )
• 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.

Latest news:

• January 2010 : Configuration tags are now read directly from the Task Request data base. A new function to compare two tag strings is available.
• November 2009 : First BEAM 2009 data09_1beam (2009-11-21) and data09_900GeV (2009-11-23)
  
• October 2009 : A page describing how AMI calculates Container Status values is available
• September 2009 : A new pyAMI user guide is available.
• The AMI replication to CERN has restarted 2009-09-14.
• A new version of the AMI python client pyAMI-03 is in the ATLAS Release from 15.4.0 up. This version allows authentication by VOMS proxy.
• CERN Read Only Server : A new AMI server is available to browse replicated data at http://atlas-ami.cern.ch  2009-07-03 .
  
• Replication to CERN :  started on 2009-06-09. 
• Monte Carlo reconstructed HITS are now being merged, and the recon TID datasets are deleted afterwards and removed from the containers. recon containers will eventually be empty. If you do not find a  particular recon dataset (mc*.recon.*_rxxx then please look for the equivalent merged dataset ( mc*.merge.*_rxxx_t*)
• Spring 2009 reprocessing   links are in the latest news page
  

Tutorials
