   4. DCAM (DCMI Abstract Model)｜都柏林核心抽象模型
      1. Purpose
         1. to specify the components and constructs used in Dublin Core metadata. It defines the nature of the components used and describes how those components are combined to create information structures. It provides an information model which is independent of any particular encoding syntax. Such an information model allows us to gain a better understanding of the kinds of descriptions that we are encoding and facilitates the development of better mappings and cross-syntax translations.
      2. Who uses DCAM
         1. aimed at the developers of software applications that support Dublin Core metadata, people involved in developing new syntax encoding guidelines for Dublin Core metadata and people developing metadata application profiles based on DCMI vocabularies or on other compatible vocabularies.

         1. Functional Requirements for Bibliographic Records
         2. is a conceptual entity-relationship model developed by the International Federation of Library Associations and Institutions (IFLA) that relates user tasks of retrieval and access in online library catalogues and bibliographic databases from a user’s perspective. It represents a more holistic approach to retrieval and access as the relationships between the entities provide links to navigate through the hierarchy of relationships.
