An island with multi-culture and a myriad of creatures

Land: 36K km 2

Population: 23M

A melting pot of multiple cultures, including: - Chinese (Holoh, Hakka…) - 20+ indigenous tribes - Immigrants from Vietnam, Indonesia, Thailand…

Home to more than 46,000 species of flora and fauna

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.

EVALUATION

QA1

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

QA2

• Discover a museum’s involved in artifact that has been an international exhibition held in Germany and selected as a journal article .

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
