In 1998, the Functional Requirements for Bibliographic Records (FRBR) model which is composed by four entities ( work, expression, manifestation and item) and their associative relationships ( primary, responsibility and subject) , was proposed by the International Federation of Library Associations and Institutions (IFLA). The FRBR model can be deployed as a logical framework for proceeding metadata analysis and developing metadata format. This paper presents a case study of the National Palace Museum (NPM) in Taipei to examine the feasibility of the FRBR model. With the diversified needs from various content communities, an analysis model is introduced at Academia Sinica to refine and enhance the FRBR model, in order to meet metadata requirements across diverse knowledge domains, which is composed of three facets ( function, subject domain, data type and style)and one supportive community layer.
