“…Although MusLib's primer ontology (R. Stewart, 2019) shares a similar structure with the ontology of the multimedia digital library "Virtual encyclopaedia of the Bulgarian iconography" (BIDL) (Pavlova-Draganova, Georgiev, & Draganov, 2007), its target and purpose differ significantly. The ontology employed in BIDL focuses specifically on the registration, documentation, and virtual exploration of icons (Pavlov, Paneva-Marinnova, Goynov, & Pavlova-Draganova, 2010), which are a distinct type of object with unique characteristics. In contrast, MusLib's objective was to develop and implement a foundational standard ontology capable of encompassing all types of objects, serving as a template for museum digital libraries in accordance with Bulgarian national legislation.…”
