今天學習的内容是Functional Requirements for Bibliographic Records[FRBR](書目記錄功能的最終報告)。該報告在製作文章中模型基本元素——實體、屬性、關係時,參考了當時很多資料與手冊。具體如下:
The principal sources used in the analysis included the International Standard Bibliographic Descriptions (ISBDs), the Guidelines for Authority and Reference Entries (GARE), the Guidelines for Subject Authority and Reference Entries (GSARE), and the UNIMARC Manual
同時全報告還定義了作爲規範重點的實體——個人、團體、概念等,并構建了他們的關係。
具體模型(文字描述):
(Group 1)four entities and their primary relationships
work(is realized through expression)
expression(is embodied in manifestation)
manifestation(is exemplified by item)
Item
(Group 2)two entities and Responsibility relationships (with G1)
person
corporate body
work is created by G2
expression is realized by G2
manifestation is produced by G2
item is owned by G2
(Group 3)four entities and Subject relationships(with G1 G2)
concept
object
event
place
work has as subject G1 G2 G3
值得説明的是,該報告研究是以實體分析技術爲基礎(entity analysis technique),這個技術關鍵的第一步就是分離特定領域的信息用戶所關心的關鍵對象(to isolate the key objects) 。也就是説,報告研究中關心的不是個體數據而是數據所描述的事物上。
