Classification of Musical Instruments

"The MIMO (Musical Instrument Museums Online) project has created a single access point to digital content and information on the collections of musical instruments held in a consortium of European museums. (...) The MIMO project has also involved the revision of the Hornbostel Sachs classification of musical instruments, with the main aim of classifying instruments such those in the new Electrophones class 5, invented since the publication of the original scheme of 1914 by Erich M. von Hornbostel and Curt Sachs. A number of scholars have at various times revised or extended the scheme.


"Die Hornbostel-Sachs-Systematik ist ein Klassifikationssystem für Musikinstrumente. Sie wurde 1914 von Erich Moritz von Hornbostel und Curt Sachs in der Zeitschrift für Ethnologie unter dem Titel Systematik der Musikinstrumente. Ein Versuch. veröffentlicht. Sie ist das heute am weitesten verbreitete System zur Einteilung von Musikinstrumenten. (...) Die Hornbostel-Sachs-Systematik ist hierarchisch aufgebaut. Jeder Kategorie entspricht eine Zahl, wobei in jedem Detaillierungsschritt eine Ziffer angefügt wird, so dass die Anzahl der Ziffern mit zunehmender Konkretisierung anwächst.

"The Hornbostel-Sachs system is a classification system for musical instruments, published in 1914 by Erich Moritz von Hornbostel and Curt Sachs in the Zeitschrift fur Ethnologie under the title Systematik der Musikinstrumente Classification of musical instruments (...) The Hornbostel-Sachs system has a hierarchical structure, each category corresponds to a number, with a number being added in each detail step, so that the number of digits increases with increasing concretization Of the number, while further characters (-,:,], +) allow the notation of special meanings.

Ontology of Anatomical Entities

"The AEO is an ontology of anatomical structures that expands CARO, the Common Anatomy Reference Ontology, to about 160 classes using the is_a relationship; it thus provides a detailed type classification for tissues. The ~100 new classes were chosen for their use in categorizing the major vertebrate and invertebrate anatomy ontologies at a granularity adequate for tissues of a single cell type.
The AEO is intended to be useful in increasing the amount of knowledge in anatomy ontologies, facilitating annotation and enabling interoperability across anatomy ontologies.
