SEKO

FMPO Finnish Medium of Performance Ontology (SEKO3)

Project on developing a new dataset as a multilingual linked data ontology and classification for better implementations in the semantic web and available for many types of organizations. Built on the information of the current Finnish medium of performance vocabulary SEKO.

Project title: “Musiikin kulttuuriperinnön yhteentoimivat tietoaineistot” (“Interoperable datasets for musical cultural heritage”)

Project objective

To develop an analyzed dataset to support Finnish music content and instrument description and preservation of cultural heritage in the Finnish organizations. The resulting dataset will be basically a semantic web linked data ontology of musical instruments and ensembles including a Finnish language version of an instrument classification.

Working titles for the dataset:

Purpose

To provide for the Finnish GLAM network of libraries, archives and museums and any other organisations for their descriptions of music content and instruments an easily accessible, usable, interoperable and reasonably comprehensive controlled vocabulary. Added value is brought with the Swedish and English labels and mappings to the corresponding concepts in international sources such as Wikidata, Library of Congress Medium of Performance Thesaurus for Music LCMPT, YSO-ontology, and the MIMO Thesaurus of musical instrument names.

Specific emphasis will be made to include traditional Finnish musical instruments extensively to support the long term preservation of the Finnish cultural heritage. Incorporating these would transform the information in the Seko vocabulary from a general medium-of-performance list into a dataset providing a definitive linked-data reference for Finnish-Karelian instruments — a unique international contribution that no other national ontology is offering, and one that strongly justifies further investment. The dataset will further provide a basis for music related knowledge graphs, research and music education.

Background

The project process is done in accordance with the Finnish expert group on music metadata (MUUSA) which maintains the Seko vocabulary.

Specific spatial and cultural information inside the current Seko instrument notes will be extracted and entered as structured linked data using e.g. YSO, YSO time, YSO-places ontologyies, Wikidata or Geospaces, etc. and formed as definitions and scope notes.

The Seko dataset consist of 1249 concepts of musical instruments and ensembles. The classification would be based on the MIMO dataset from 2011 and its addtions in 2018 which will be translated and entered in skos-format with Finnish labels to support browsing the instruments by classification.

Funding applications pending. Contact Jarmo Saarikko if you are interested in joining or sharing your expertise.

Data model of the vocabulary / ontology

Mappings

During the process we map items in Wikidata with the corresponding SEKO-ID (P10063). To support mappings, see also other identifiers in Wikidata LCMPT ID (P8516) and MIMO instrument ID (P3763), UNIMARC: Medium of Performance ID (P11214), MusicBrainz instrument ID (P1330).

The skos:MappingRelations properties will be used to link to external sources. Preferrably with exactMatch, but also closeMatch, broadMatch and narrowMatch may be used when an exact match is not available.

Current plan is to map to Wikidata and to an external authority file. Wikidata mapping would be considered mandatory. The existing LCMPT mappings are checked and their coverage extended. Possibly map to any vocabulary that Finnish music archives and museums are currently using.

Classification

Library data: BIBFRAME and MARC21

For content description purposes the appropriate concepts in SEKO3 could be marked as instances of bf:MusicEnsemble or bf:MusicInstrument or bf:MusicMedium</b>.

In MARC21 data records the labels of SEKO concepts can be used in the 382 field and other fields. The MARC21 source code identifier for the vocabulary is “seko” (subfield $2 value)

Museums and Archives

Museums and instrument collections

Finnish museums are already using the KOKO ontology

KOKO incorporates the MAO/TAO ontologies maintaned by the museums. – A suggestion and an easy solution might be to include the whole FMPO into KOKO as its top conepts are YSO-concepts.

Content description in Finnish Museums

Music archives

Networking

The project aims at networking internationally with professionals that are working with metadata and vocabularies related to musical instruments

Data

The source data is is comprised of three datasets that will be worked in parallel and eventually can be combined into an unified interoperable lined data service.

  1. The current dataset of Seko of 1241 titles.
  2. The Hornbostel-Sachs classification by MIMO which, when translated in Finnish, can be used as an optional browsing interface to the Seko instrument data as well as serve music and organological research and teaching.
  3. A vocabulary of the Finnish-Karelian traditional instruments, many of them not currently available in online interoperable voacabularies, but are represented in Finnish collections and research publications and some of them available through finna.fi and Europeana.

Outside of the scope, but it might also be possible to develop this separately as an ontology of folk instruments of the peoples speaking Finnic languages or even a Scandinavian-Baltic-Finnic folk instrument ontology, which might be a valuable resource for research and collections.
