Sponsored by the National Science Foundation 2 March 15, 2011 Use Case 4: Experimenter (or Operator) moving MD to an archive, with an option to share with other Researchers An Experimenter (or Operator) can move MD Objects (directories or files) to (and from) a Type 2 User Workspace (UW) service Always includes associated MD Object Descriptor (“metadata”) Identifiers and annotation in Descriptors allow Experimenter (or Operator) to manage thousands of files gathered during an experiment, or when monitoring infrastructure The Experimenter (or Operator) can move selected MD Objects (directories or files) from UWservice to the Type 4 Digital Object Archive (DOA) service, to become persistent Digital Objects Digital Object receives a persistent global identifier Digital Object includes an associated Descriptor Descriptor includes sharing policy, that DOA service is obligated to follow

Sponsored by the National Science Foundation 3 March 15, 2011 Type 4 I&M Service: With portal to share MD Each Type 4 I&M service: Has web portal to observe and share MD Web portal authorization mechanism required to admit only specified users; should reuse accepted certificate/credential arrangements Example: Presentation service that is part of Instrumentation Tools Example: Digital Object Archive (DOA) service prototype from CNRI DOA service required to follow sharing policy within Descriptor associated with a Digital Object

Sponsored by the National Science Foundation 4 March 15, 2011 User Workspace Service Each User Workspace (UW) service: –Is a Type 2 common service, assembled, configured and managed by a Service Provider in their sliver using Control Framework (CF) mechanisms –Service Provider offers UW slivers (e.g., Linux file systems) to Experimenters and Operators via CF mechanisms –UW service sliver is a resource to be obtained by an Operator via CF, and then configured and managed –Policy is required to make sliver available to selected experimenters and operators

Sponsored by the National Science Foundation 5 March 15, 2011 Digital Object Archive (DOA) Service Each DOA service: –Is a Type 4 service with a web portal to observe and share MD –Required to follow sharing policy within Descriptor when sharing Digital Object –Policy required to make digital object available to selected users within GENI, selected users outside of GENI, and/or all others
