This website aims at maintaining cultural heritage.
Cultural heritage consists of physical and non-physical artifacts (stories, pictures, instruments, documents, language) that are inherited from past generations, and that are kept because these are part of a culture (of a group, a society, a family). These artifacts are instrumental in keeping this culture alive, as long as people continue to live the culture and use the artifacts and maintain them. Maintaining the artifacts includes transferring temporal ownership: to individual members of the culture, to institutes (keepers, libraries, museums) as well as transferring all relevant knowledge related to the artifact, its use, and the culture of use.
Living cultures, by definition, regulate maintenance, even if all cultures develop and change. When changes are abrupt, e.g., when a culture merges with another one or is taken over, the life of the original culture is in immediate danger, and so is the meaning of the cultural heritage: objects may get lost or mutilated and the related knowledge may be lost. From then on these objects have lost their original meaning, even if they might be considered pretty, interesting, or valuable in their new cultural environment.
