FRBRoo Based Metadata Description and Integration for Art Collections An Ontology Approach Presenter: Ya-Ning Chen Ya-Ning Chen1 & Hao-Ren Ke2 1Computing Center, Academia Sinica 2Graduate Institute of Library & Information Studies, National Taiwan Normal University Outline • Background – TELDAP(Taiwan E-Learning and Digital Archives Program, 2008-2012, prior project: NDAP) – Heterogeneous metadata description and integration • • • • • Proposed Approach Use Case Evaluation Discussion Conclusion 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… Home to more than 46,000 species of flora and fauna 4 Content Types • • • • • • • • • • • • • • • • Anthropology Archaeology Architecture Archive Artifact Audio & Video Botany Calligraphy & Painting Chinese Classics Geology Journalism & Mass Media Language Map & Remote Sensing Rare Book Rubbing Zoology 5 PLATFORM: Union Catalog http://catalog.digitalarchives.tw/ • The Union Catalog of TELDAP contains millions of digital objects from local & overseas content holders. Metadata: 5,152,805 Images: 4,012,959 Multimedia: 48,597 6 metadata 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. FRBRoo FRBRoo Align together FRBR From ER model to OO Model CIDOC CRM USE CASE HKM Digitized into Original Items Multispectral images Digital images Described by Described by Dublin Core Exported into Digitized into CDWA TELDAP Union Catalog Converted from CDWA into DC A: Metadata and DL system Original Item A NPM Has participated in Event An international Exhibition Is part of Is a topic of Original Item B B: Metadata and DL system Is described by Published Journal Article The National Palace Museum Monthly of Chinese Art 故宮文物月刊 PATH-BASED MAPPING Path-based mapping-1 Target Domain Target Path Source Domain Target Range Source Range Source Path FRBRoo Entity Metadata Element Target Path Source Path FRBRoo Entity Metadata Element Path-based mapping-2 Museum’s Object E77 Persistent Item E39 Actor E21 Person E14 Group Hierarchical Relation • /E77 Persistent Item/E39 Actor • /E77 Persistent Item/E39 Actor/E 21 Person • /E77 Persistent Item/E39 Actor/E 14 Group DC’s Creator or Contributor Path-based mapping-3 Literary Work-Library P14 carried out by(performed) F27 Work Conception E39 Actor E21 Person E14 Group Semantic Relation /F27 Work Conception/P14 by(performed)/E39 Actor carried out DC’s Creator or Contributor TOPBRAID IMPLEMENTATION FRBRoo of TopBraid 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. Right owner Right creator Autumn Begins 立秋 Acquisition Event Various digital formats for the same original item.

Grid trellis of Round Treasure Box with Indian Lotus Décor (Ch’ing dynasty, Chinese: 清 竹絲纏枝番蓮圓盒多寶格) Source: http://catalog.digitalarchives.tw/item/00/0c/c6/93.html 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 Thanks for your attention.
