Facilitating international sharing
• IFLA Working Group on an International Authority System
• Guidelines for Authority and Reference Entries• Guidelines for Authority Records and References• UNIMARC Authorities• International Cooperation in the Field of Authority
Data• Minimal Level Record for Internationally Shared
Resource Authority Records• Working Group on Functional Requirements and
Numbering of Authority Records (FRANAR)
Objectives
• Specify data requirements
• Define data structures
• Develop an international numbering scheme
Issues
• Understanding the function of the data– data supporting identification
• data embodied in the heading (e.g., name, dates)• data recorded in cataloguer’s notes (e.g., field of
activity)• data recorded in coded form (e.g., nationality, gender)
– data supporting integration• data identifying the source and status of the record• data identifying the language of the record or data
element• data identifying scripts, transliteration schemes,
character sets, etc.
Issues
• Clarifying data definitions– differentiating categories of data elements
• e.g., distinguishing between “name” and “addition”
Leighton, Frederick Leighton, Baron
Beeton, Mrs.
– clarifying underlying concepts• e.g., nationality (place of birth? citizenship? place of
residence?)
Du Jardin, Thomas [birthplace: France; residence: France]

Issues
• Potential for automatic editing– complexities in language of cataloguing

• Accommodating differences in cataloguing rules and practice– recognition of discrete entities (e.g., author who
uses one or more pseudonyms)
Issues
• Administration of an international numbering scheme– responsibility for assigning an ISAN
• jurisdictional responsibility• first-in
– procedures for ensuring validity of assignment• international register• national/regional registers
– linking authority and bibliographic files• adding ISANs to heading fields in bibliographic records
