USING PREMIS TO AUTOMATE RIGHTS MANAGEMENT

Bradley D. WestbrookHead, Metadata Analysis and Specification UnitDigital Preservation Workshop, 15 October 2009

The UC San Diego Libraries Digital Asset Management Coordination Group is collectively responsible for the work described in this presentation. Members are: Robin Chandler, Matt Critchlow, Declan Fleming, Chris Frymann, Cristela Garcia-Spitz, Rob Joyce, Gabriela Montoya, Joy Sargis, and Steve Wieda.

• UCSD Digital Asset Management System– 250K+ objects

– Heterogeneous content, formats, and sources

• Ad hoc management of rights data– Rights assigned frequently at collection level

and independent of object level metadata• Some objects unduly restricted

• Not all rights data transmitted with objects

– No procedure for managing expiration of restrictions

– Not reliable for supporting a harvesting service

Problem Summary

Oct. 7, 2009 PREMIS Implementation Workshop

• Implement object-based metadata practice

• Determine access status

• Enable override of access status

• Automate updating metadata

• Phased implementation

Targeted Solution

• Required for each digital object– Copyright status

– Copyright jurisdiction

– Copyright note for naming rights holder

– Copyright note for intended use

– Copyright note for limits on use

Copyright information

Oct. 7, 2009 PREMIS Implementation Workshop

• Required when applicable– Act

– Restriction

– Start date

– End date

License information

• IF premis/restriction =”Display currently prohibited” THEN accessPermitted=”False”

• • ELSE IF premis/rightsGranted/act=”Display” THEN

accessPermitted=”True”

• ELSE IF premis/copyrightStatus=”Under copyright” | “Unknown” THEN accessPermitted=”False”

• ELSE IF premis/copyrightStatus=”Copyright UC Regents” | “Public Domain” THEN accessPermitted=”True”

• Results in two data caches: “Access Denied” & “Access Provided”– accessPermitted “Yes | No”– accessDateAssessed

Access Status Determination

• Confirms results of first step

• IF premis/restriction=”Display currently prohibited” THEN access permitted changed to “FALSE” and object removed from Access provided group

• IF premis/copyrightStatus=”Under copyright” | “Unknown” THEN access permitted changed to “FALSE” and object removed from Access provided group

• Any objects for which access was errantly permitted will be flagged and access status will be corrected. At conclusion of process Group A2 should not include any objects for which access is not permitted as determined by rights status of the object.

Access Status Check

• Access status override

• Access approving agent

• Access status override date

• Access status override note

Overriding Access Status

• Restriction:– IF premis/restriction = "Display currently

prohibited" – AND premis/dateEND is < Current Date, – THEN change accessPermitted from "False"

to "True" – AND delete premis/restriction,

premis/beginDate, premis/endDate (OR notify DLP that restriction's for identified objects have expired and request that metadata be updated).

• Copyright (Rules to be developed)

Updating Rights Metadata

• Periodic application:– Updates– Access status determination– Access status check– Record access status– Add overrides (manual)

• Reports– Tally of objects at start of process

• “N” DAMS objects assessed for access status on YYYY-MM-DD– Tally of objects assessed as being publicly accessible

• “N” DAMS objects were determined to be public accessible on YYYY-MM-DD

– Tally of objects corrected from publicly accessible to not publicly accessible

• “N” DAMS objects had access status corrected to “False” on YYYY-MM-DD

• List objects by ARKs
