The functional model of NDDA is based on a principle offering a novel dissemination method, which was developed by an international scientific community. The essence of the so called Open Archive Initiative (OAI) model is separating data provider and service provider roles.
Data providers preserve digital contents, document, i.e. digital objects as well as generate and maintain information describing these. Data providers retain handling and full control of content.
According to the model, the content’s descriptory information shall be disclosed to the public. Service providers build value-added services on this basis.
If operation is smooth while roles and functions are separated (operated by independent parties), then it really is an open archive architecture.
