Ecomuseum has goal preservation
General involvement;
Shared responsibilities;
Interchangeable roles: public officers, representatives, volunteers and other local actors are all playing a vital role in an ecomuseum.Community involvement does not mean that local administrations, a unique historical heritage of European democracy, are irrelevant. On the contrary their role, to be effective, must involve people, going beyond the narrow circle of “authorized personnel”.
Preservation, interpretation and management means that reading and communicating heritage values, providing new 
interpretations of it and raising its profile, are part of the day-to-day activity for ecomuseums. Heritage is very close to Place as a notion, including history of inhabitants and things, what is visible and what it is not, tangibles and intangibles, memories and future.
Sustainable development is a central issue for ecomuseums and it implies also to increase the value of a place instead of diminishing it. Evidence from best practices identifies in this process two key elements: place-based development, as previously described, and the improvement of local networks, where ecomuseums have to play a key role as catalysts of social capital development.
Agreement means a mutual consent, implying reciprocal commitments between local players. The Polish national meeting, once more, put forward the idea of “voluntary meeting of people”.
