HPSS, SRB, MCAT

• HPSS: Storage/Archival of large datasets• (UCB, UCSB, Stanford)

• SRB/(E)MCAT: Data Handling/Information Discovery• transparent access to remote storage• replication• containers for large number of small items• caching• authorization• proxy operation support (filtering, data subsetting)• usage of security infrastructure (GSI)

Managing Metadata: EMCAT

• Extensible Meta Data Catalog - EMCAT• Exploits dependencies & relationships (m:n, tc, <=>, …)• T-Language - Markup, Filter & Presentation• Meta Data Repository (Object-, System-, Collection-level)• Based on Kernel Meta Meta Data • Extensible • Uniform Access and Federation interface• Metadata exchange Interface Protocol

• MAPS- Meta data Attribute Presentation Structure• query, update and result structures• Close to Z39.50



SRB/MCAT Future

• Performance Improvements and Consolidation• Delayed Action Manager - mirror, cronjobs• Support for Methods• Handling Very Large Data sets - partitions• More Drivers - Sybase, NTFS, LDAP• Extensible MCAT• Language Support - Perl, Fortran
