###### Abstract  
The concept of tangible cultural heritage has been defined a long time ago and international legal acts have been created to protect, preserve, and popularize it. The most significant act is the \"Convention Concerning the Protection of the World Cultural and Natural Heritage\" adopted by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 1972 [1]. This convention obliges the members of the United Nations that have ratified it to protect their cultural and natural heritage. Material heritage is understood as a physical element of the heritage of humanity [1], and includes archaeological sites, historical monuments, artifacts, and other objects, as well as natural elements, such as physical and biological formations, geological and physiographical formations/areas, and natural sites/areas with high value for science, conservation, or natural beauty. The intangible heritage of humanity was noticed much later. It was only on October 10, 2003 that the \"Convention for the Safeguarding of the Intangible Cultural Heritage\" was adopted by UNESCO [2]. Intangible cultural heritage is understood as, among others, \"oral traditions, performing arts, social practices, rituals, festive events, knowledge and practices concerning nature and the universe or the knowledge and skills to produce traditional crafts\" [3]. Intangible heritage understood in this way is inherited from our ancestors and should be passed on to our descendants as achievements of humanity. Intangible heritage is quite fragile because it mostly functions in human memory and if not \"cultivated\", it disappears, i.e., is forgotten. At the same time, it is a testimony to cultural diversity that should be maintained in the face of growing globalization and unification. Older technologies, such as analogue photography, sound, and video recording, are now being replaced by digital ones. Information Technologies (ITs) bring a new quality to these activities. However, [4] points to the relatively low dissemination of IT applications in the area of the intangible heritage of humanity. IT has been and can be used in various ways in the broadly understood field of cultural heritage. This use may include, but is not limited to, the following areas: documentation, protection, reconstruction, restoration, conservation, dissemination, and popularization. Documenting is primarily the registration of the condition of an existing tangible artifact or of elements of intangible heritage. For this purpose, various IT tech can be used: examples include digital photogrammetry, 2D and 3D scanning using different technologies, and digital recordings of voice, image, and character movement [5; 6; 7; 8; 9]. Protection primarily entails the use of IT in the areas of physical protection of objects of tangible cultural heritage. For this purpose, all types of supervision and access protection systems are used [10; 11]. Reconstruction is supporting the physical reconstruction of lost elements (e.g., vessels, paintings, or buildings) or conducting this kind of reconstruction in the digital realm (e.g., creating digital twins of currently non-existent cultural heritage artifacts) [12; 13; 14]. ITs can be used to support restoration and conservation works through spectral or statistical analysis of colours, materials, or technologies and through computer-aided planning of restoration/conservation activities [15; 16]. Dissemination is the provision of information about cultural heritage to various social groups (e.g., scientists, guides, tourists). Modern ITs significantly reduce its costs and expand the range of recipients. They also increase the variety of data provided [17; 18; 19]. Popularization means providing a wide public with information about elements of cultural heritage. The IT tool used here is the Internet, thanks to various portals promoting cultural heritage [20; 21].
