Lex – Danmarks Nationalleksikon vs Vikidia

Lex – Danmarks Nationalleksikon is Denmark’s freely accessible, searchable national encyclopedia, with Danish-language factual content written by researchers and other professionals. Its collection contains more than 245,000 articles, including Den Store Danske, Trap Danmark, and other specialist reference works. Editors continually add material and revise existing articles. Trap Danmark covers subjects including geography, biology, archaeology, history, culture, architecture, and social and business life; its digital edition includes place descriptions, maps, images, and illustrations from public cultural and geographic databases. Lex provides definitions from Den Danske Ordbog within its articles. Readers can comment, suggest edits or new articles, and contribute images, though editors must approve proposals. Lex says articles may contain errors or omissions and invites correction suggestions. Institutions, public authorities, and businesses can license content through Tekst & Node. Text and data mining, including AI training, requires individual permission. Lex serves public education, including schools, universities, educational institutions, and libraries.

Vikidia is a free collaborative online encyclopedia designed mainly for readers and contributors aged 8–13. It runs on the web, and anyone may improve articles, layouts and organization. Articles are expected to be verifiable and neutral, using language and presentation appropriate for that age group. Editing can be anonymous or tied to an account, with earlier versions saved so changes can be restored. Content may be copied, modified and redistributed under CC BY-SA 3.0 and GNU licenses when attribution and license terms are retained. Vikidia supports school projects with guidance, examples and contact information for teachers and students. Its legal information says children are not asked for real names and registration email is used only for technical purposes. The Vikidia association, a French non-profit founded in 2006 and headquartered in Rennes, maintains the site without advertising and accepts donations. Help is available through The Scholar page, chat, Discord and IRC. Hosting is provided by OVH.
