Tangible cultural assets decay, intangible assets might get forgotten and digital ones might become obsolete as time passes. Thus, safeguarding the cultural heritage, tangible, intangible and digital, is crucial. Digitization plays a notable role in safeguarding tangible and intangible cultural heritage. The digitization of cultural heritage refers to the interdisciplinary domain that encompasses management of cultural heritage in the digital environment (Manzuch, Huvila & Aparac-Jelusic, 2005).
Digital cultural content helps to capture cultural memory and preserve it for future generations. Various creative expressions and resources of information are increasingly produced, distributed, accessed, and maintained in digital form (Cameron & Kenderdine, 2007). In regard to preservation of cultural heritage, constantly increasing amount of content is one of the biggest challenges faced by cultural heritage institutions. Another challenge appeared in digital era is about the relatively short life of most digital objects due to the media they are recorded on and the software that runs that media. Both the media and the software are under the risk of becoming obsolete when time passes and that makes information inaccessible (Rothenberg, 1995).
