BACKGROUND
Development in Taiwan
An island with multi-culture
and a myriad of creatures
 Land: 36K km2
 Population: 23M
 A melting pot of multiple
cultures, including:
- Chinese (Holoh,
Hakka…)
- 20+ indigenous tribes
- Immigrants from
Vietnam, Indonesia,
Thailand…

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
FRBROO
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.
CIDOC CRM
• A Conceptual Reference Model for museums
released by International Committee for
Documentation of the ICOM(International
Council of Museums) in 1999.
• In 2006 CIDOC CRM was completed with its
acceptance as the ISO 21127 standard.

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 artifact that has been
involved in an international exhibition held in
Germany and selected as a topic in a published
journal article.

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
