ISSUE

Heterogeneous Metadata Integration An interoperability issue Diversity – Various communities, including archives, libraries, museums and herbariums. – Various metadata formats and their records, such as CDWA, EAD, DC(Dublin Core), MARC, and so on. Current approach – DC-based mapping or crosswalk – Semantic relations embedded in metadata elements are ignored and lost during mapping.

Proposed Approach Inter lingua: FRBRoo Path-based mapping between metadata elements and FRBRoo (Kondylakis et al., 2006) – Semantic crosswalk – Semantic relations – Core classes and properties Tools: TopBraid Use Case – The collections of Hwa Kang Museum (HKM) of Chinese Cultural University. – The collections of Chinese Antiquities at the National Palace Museum (NPM) Question Answering (QA) based Evaluation

FRBR OO

FRBR FRBR: Functional Requirements for Bibliographic Records. FRBR is a conceptual model for bibliographic records for literary and artistic works released by IFLA(International Federation of Library Associations and Institutions) in FRBR can be also regarded as an ontology for bibliographic universe for libraries.

CIDOC CRM A Conceptual Reference Model for museums released by International Committee for Documentation of the ICOM(International Council of Museums) in In 2006 CIDOC CRM was completed with its acceptance as the ISO standard.

Discussion One-to-one principle – A shared classes and properties of FRBRoo – Semantic relationships and queries Ontology-based alignment of heterogeneous metadata integration for museum’s objects and library’s literary works – Keep two different documentation approaches intact and parallel – Align rather than to change one approach and its metadata to fit the other

Conclusion FRBRoo: an inter lingua (i.e., a shared ontology) Explicit semantic relationships embedded in metadata elements Transform human-understandable metadata into machine- readable and understandable representation with RDF’s expression Semantic query A shift toward the semantic web
