  1. Descriptive metadata in the Finnish National digital library and the role of CIDOC CRM in the standards portfolio of NDL Juha Hakala The National Library of Finland

  2. Administrative and descriptive metadata in NDL A set of mandatory elements of administrative metadata has been agreed in December 2009 • Libraries, archives and museums may need to change their current practices significantly • METS, PREMIS, MIX among the relevant standards • There are no mandatory elements for descriptive metadata, but there may / will be recommended practices to improve the search results in the public interface • Usage of Generic Finnish Ontology / Thesaurus for subject analysis in libraries, museums and archives. www.kdk2011.fi

  3. Descriptive metadata: exchange formats • MARC 21 (http://www.loc.gov/marc/) & FINMARC • Dublin Core (http://www.dublincore.org/) & MODS • EAD (EncodedArchivalDescription; http://www.loc.gov/ead/) • EAC (EncodedArchivalContext; http://www.library.yale.edu/eac/) • CDWA (Categories for the Description of Works of Art; http://www.getty.edu/research/conducting_research/standards/cdwa/) • CIDOC-CRM (CIDOC ConceptualReferenceModel; http://cidoc.ics.forth.gr/) • SPECTRUM (Standard ProcEdures for CollecTionsRecordingUsed in Museums; http://www.mda.org.uk/spectrum.htm) • VRA Core (http://www.vraweb.org/projects/vracore4/index.html) • Film identification - Minimum set of metadata for cinematographicworks (EN 15744) www.kdk2011.fi

  4. Metadata processes: public interface The relevant elements of 11 metadata formats used for data exchange will be normalised into the internal format of the NDL public interface (in CIDOC CRM terms: NDL materialized access system) Internal format is a dead end: its design will be solely based on the user requirements related to search & display of records in the public interface; metadata will never be converted from there to other system Metadata records are harvested with OAI-PMH from the source systems; if necessary, this process can be repeated www.kdk2011.fi

  5. Metadata processes: public interface (2) Normalisation involves two distinct steps • Mapping of elements • Normalisation of data (e.g. Date information) Format experts will be responsible of mappings Not clear to what extent existing tools such as VMF can and will be used; this depends on how “standard” the internal format will be Data normalisation will be carried out by IT specialists www.kdk2011.fi

  6. Challenges Lack of detailed understanding of incoming metadata Formats & cataloguing rules may have been used in a creative manner There are local elements which may be relevant for public interface and other systems -> local modifications for normalisation rules No off-the-shelf mappings between all 11 formats Each new 3rd party system may require a lot of work Lack of rigorous authority control / authority database One person / organisation, many names (KustaaMauriArmfelt, Gustav MauritzArmfelt) Diversity – records may have little in common www.kdk2011.fi

  7. The role of CIDOC CRM Cataloguing format in the Muusa (Muse) system Common tool for the exchange of “curated knowledge of museums” One of the 11 exchange formats in the NDL project When CRM has been harmonised with the models used in libraries and archives (and when the necessary migration tools have been developed), it could be used as a means for exchanging curated knowledge of libraries, archives and museums As a rich and extensible ontology, CRM can accommodate “everything” much more easily than e.g. MARC 21. www.kdk2011.fi
