PAWN: Producer-Archive Workflow Network University of Maryland Institute for Advanced Computer Studies Joseph Ja’Ja, Mike Smorul, Mike McGann

Ingestion Process Producer: An organization or entity that creates records to be archived Record selection Package creation Transmission Validation Approval or rejection of package contents Storage into archival system

What is PAWN? Software that provides an ingestion framework Handles the process From package assembly To archival storage Simple interface for end-users Flexible interface for archive managers Designed for use in multiple contexts

Administration Overview Organizational hierarchy Record schedules User roles User accounts Record sets Authorize users Approve or reject submissions Push approved data to archival system

Organization hierarchy Domains: Logical unit of administration and delegation Domain contains its own set of: Producers Record schedules Record sets Managers Each producer belongs to a domain. Each manager controls actions within a specific domain. Domains can contain additional subdivisions

Example Domain: Department of Agriculture Division: Economic Research Service Division: Agricultural Marketing Service Division: Department of Defense Domain: Defense Logistics Agency Domain: Department of the Navy

Record Schedules List of disposition authorities Contents of packages map to an authority Example: USGS Geospatial, Cartographic, Remote Sensing… Authority: Data Layers by USGS ( c) Authority: Documentation ( e)

User Roles Determines availability of services Create record schedules? Create users? View packages? Reject or approve packages? Submit packages? Administrator, Records Creator, Records Liaison Officer, Records Manager

Record Sets Producers are presented with record sets Logical archive units Map producer-friendly categories to archive-friendly disposition authorities Record set has a group of allowed users

Example Record Set: Avian Point Counts Category: Tabular Data Maps to: Data Layers by USGS ( c) Category: Vector Data Maps to: Data Layers by USGS ( c) Category: FGDC Metadata Maps to: Documentation ( e)

Producer Workflow Overview Stage required data Select record set Use builder to assemble package Submit package to archive

Package Builders Different builders can be used for different data Default builder provided Customized builders could: Automatically identify metadata Convert data or metadata Automatically structure data Example: ICDL Book builder

Package Workflow Overview Manager views list of packages Newly received packages need approval Once approved, packages can be archived Rejected packages can be held until rectified or deleted for a resubmission Audit trail tracks all workflow steps

Components of PAWN Management server Receiving servers Scheduler Certificate authority Data grid for storage Client program for ingestion and administration

Components of PAWN

Management Server Users and authentication Record Schedules Submission agreements Permissions and authorization Package workflow progress

Receiving Servers Entry point into archive Verifies integrity of submission package Send packages to validation services Holds packages before pushing to archive system

Supporting Components Scheduler Tracks receiving servers Clients ask scheduler for an available receiving server Receiving servers ask scheduler for configuration information Certificate Authority Generates certificates for digital signatures

Client Program User interface for the PAWN system Java web-start program Allows producers to create packages and send them to the receiving servers Allows managers to administrate and monitor the PAWN system
