Introduction • Globus MDS – GRIS and GIIS • BDII is the Berkeley Database Information Index • Or something to this effect • Implementation from CERN • Depends on GIP – Generic Information Provider plugin • GIP generates dynamic information • Combined with static information from files
Hierarchy - publishing TopLevel All sites in WLCG GIIS site GRIS GRIS Resource
MDS • Essentially LDAP, using GLUE schema • Plus some extra stuff • Objects with attributes with values • Objects are identified with objectClass attr
Hierarchy Glue Service Control GlueSE Access GlueSA GlueVOInfo Built with Distinguished Names
Naming • o=grid • mds-vo-name=local • mds-vo-name=ral-lcg2 • glueseuniqueid=srm-atlas • gluesalocalid=atlassimraw • gluevoinfolocalid= atlasSimRaw:vomap50160 Top level BDII sitename SE SA VOInfo
