<observables> </physics> records useful info. to search ensembles • QCDml is an XML-based markup language • designed for ILDG • QCDml XML documents describe metadata • of QCD ensembles and configurations in ILDG • stored in ILDG Metadata Catalogue and • searched by users • QCDml schema define XML elements • necessary for exchanging configurations • provide standards of notation and terminology • based on common community practices • to ensure unique markup • XML documents have to conform to schema <size> <elem> <name>X</name> <length>28</length> </elem> <elem> <name>Y</name>

management section of configuration XML includes <crcCheckSum>347437280</crcCheckSum> Summary and More • markovChainURI • unique name of the ensemble • common in ensemble and config XML •

format:lfn://Regional-Grid/......... • markovStephas • update: unique number of configuration, e.g. trajectory# • series: distinguish different runs for the ensemble • avePlaquette: used to check configuration integrity • to learn more about QCDml • visit http://www.ccs.tsukuba.ac.jp/ILDG • study sample XML files • ask MDWG member • Lattice actionsbecoming complicated • minimal explanation is embedded in QCDml schema • human readable documents including mathematical expressions • and reference articles will be prepared • latest version http://www.lqcd.org/ildg/QCDml • ensemble1.4/QCDmlEnsemble1.4.1.xsd • config1.3/QCDmlConfig1.3.0.xsd • meets (almost all) requirements of the community • changes (e.g. addition of more actions) will be made • on request by the community Working group members G.Andronico (INFN), P.Coddington (Adelaide), C.DeTar (Utah), R.Edwards (JLAB), B.Joo (JLAB), C.Maynard (Edinburgh), D.Pleiter (NIC/DESY), J.Simone (FNAL), T.Yoshie
