  1. Information Modeling and GLUE 2 Sergio Andreozzi INFN-CNAF Bologna

  2. Information Modeling • JRA2 Activity (New Services) has identified the need for an information model as an open standard for Computing Resources as a top priority • Missing connection between OGSA-BES + JSDL • The project committed JRA2 to fully invest the second year of activity to fill this gap • The activity is already well set and is progressing nicely • OGF considers already GLUE 2 as an important milestone for the standardization • Participation to the OGF activity for the definition of the next-generation information model for computing resources as a community standard • co-leading OGF GLUE WG

  3. Expected Contribution • Implementation of the GLUE Schema • in XML Schema for the integration into OGSA-BES and other WS-based services • in LDAP Schema for the integration into current OpenLDAP-based Grid infrastructures • e.g.: BDII-based information service in EGEE • Implementation of an extensible information providers framework for computing resources based on Open Pegasus framework (DMTF/WBEM technologies) • Server running providers, support for caching, attention to performance • Client rendering the information in XML and LDIF • Timeline • Prototype implementation for early evaluation available in november ’07 (only XML) • based on OGF21 draft of the spec • Production release available by March 2008 (XML + LDAP) • Based on expected public comment version of the spec to be issued on OGF22 • Note: • the implementation of info providers for storage systems are not part of our current plan • planned for initial part of OMII-EU II • the framework that we will deliver, will enable third parties to easily plug their providers
