PRODEJCI ZVUKU ONLINE: VZNIK A VÝVOJ DATABÁZE ZAMĚŘENÉ NA OSOBNOSTI RANÉHO ZVUKOVÉHO PRŮMYSLU V ČESKÝCH ZEMÍCH.

Purpose - The article presents the circumstances surrounding the development of a specialized database that gathers information about individuals and entities involved in the trade and distribution of historical sound carriers and, more broadly, in the development of the early sound industry in the Czech lands. The article traces the entire process of development the database, from initial research on historical sound documents at the National Museum to the mapping of related archival materials, culminating in the development of the presentation web platform. Design / methodology / approach - The article is a case study describing and analyzing the creation and development of a specialized thematic database, presenting its functions and data structure. The contribution demonstrates how the database was modeled based on digital objects, data, and metadata primarily obtained from the collections of the National Museum, supplemented by materials from other Czech libraries, archives and museums and private collections. Results - The article is a case study describing and analyzing the creation and development of a specialized database, presenting its fundamental functions and data structure. The contribution demonstrates how the database was modeled based on digital objects, data, and metadata primarily obtained from the collections of the National Museum. Originality / value - The article illustrates that the creation of a specialized database was the only way to unify and interconnect previously fragmented and incomplete archival materials, sound recordings, and other products of the early sound industry. According to the authors, the emerging specialized database also has future potential for evaluating the subject matter in an international context (including the Central European and transatlantic connections of the early sound industry).
