The Slovene Ethnographic Museum (SEM) is committed to the optimal accessibility of cultural heritage to all segments of society, including access to the online environment. The museum website used to be relatively well accessible: it allowed visitors to increase the font size and to select contrast as well as contained a good search engine and site map. Administrators deliberately avoided ads, flash animations, etc. As for the programming, the website was also good, allowing
screen readers (e.g. JAWS) to skip blocks and to select chapters. Following the discussion with vulnerable groups and considering the recommendations, Slovene Ethnographic Museum decided to upgrade its website in order to increase its accessibility and universality. The museum thus abandoned rotating banners on the main page, avoided giving only graphic information and added linguistic equivalents, included clearer and fewer menus and site navigation via keyboard, highlighted accessibility information on a special subpage and used more precise textual alternatives to photos. The website was also optimised for mobile devices (tablets and phones) using responsive design. Upgrade and modernisation resulted in a consistent website; texts are written in simple Slovene and audio elements are added (guides, explanations, etc.). When upgrading its website, the SEM followed the Web Content Accessibility Guidelines 2.0 or WCAG 2.0 standard. The SEM was aware of the fact that it is difficult to design a website that would be tailored to all people at all levels. Some of the content should thus be aimed at specific people (e.g. it is impossible to convert a subtle art video into a text). Nevertheless, it is possible to create a website that is accessible in most situations and provides alternative contents (text, video in sign language or audio description). The museum took into account the universal principle (basic information is accessible to all) and the principles of comprehensibility and individualisation gained through hierarchical information (specific information is accessible to a specific target audience). We can say that also accessibility to our collections (objects and photographs) and publications archive (journal Etnolog and other publications) is much better.
