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
• 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 1998.
• FRBR can be also regarded as an ontology for bibliographic universe for libraries.

QA1
• An artifact of museum has transferred the right from creator to museum through an acquisition event and has various formats of digital images.

Discussion
• • One-to-one principle – A shared classes and properties of FRBRoo – Semantic relationships and queries Ontology-based alignment library’s literary works of heterogeneous metadata integration for museum’s objects and – 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
