Short description: The purpose of the Danish Addresses Web API (DAWA) is to offer users access to data and functionality relating to Denmark's Authoritative Addresses. The value of DAWA's address data was considered from two primary 'effect levels’ (efficiency and innovation), and from the level of derived social benefits.

For the calculation of efficiency gains, use was made of existing literature cases, information about the actual use of the DAWA (number of users, number of calls, most used services and ways to use them) and assessment of savings in a sample of organisations. A questionnaire was used to verify the efficiency calculations, as well as to understand derived benefits including the value of DAWA as a key driver in the use of other data. The analysis was accompanied by a sensitivity assessment to evaluate its degree of trustworthiness.
