Multiple Resolution @ CrossRef

MR has been ‘in the works’ for a long time
-1995/99: Handle and DOI documents speak of multiple resources
-2000: Appropriate copy solutions emerge
-2003: CrossRef implementation discussed at IDF annual meeting
-2004: CrossRef begins pilot of ‘menu-based’ MR
-2005: Focus shifts to “interim-page” MR, need for country code based MR expressed at IDF annual meeting
-2006: MR pilot registers 40,000+ DOIs with interim page service
-2007: Country code based MR implemented by CNRI, CrossRef adopts CNRI.RSC_LOC approach, implements ‘production’ scale MR service
MR solution has two parts
1) Handle system data representation and resolution processes
• Best done collaboratively (ex. IDF)
• Best implemented centrally (e.g. CNRI)
2) Data management
• Deal with needs of a specific community (ex. CrossRef)
• Provide a service for these users to maintain Handle data
• Provide neutral intermediary services

MR data in Handle: pilot
MR data in Handle: production
Neutral intermediary services ?
• Interim page is a way-point
• Users decide
• Independent of any target hosting platform
www.crossref.org/iPage
Interim page is template driven
Concerns
• Multiple participants with independent objectives
• Permissions
• Education (redirection confuses everyone)
• Merging overlapping data
Questions?
