The DIN SPEC 91300 series provides guidelines for the development of a business model for an organization with the business objective of arranging and providing home related services. Part 3 describes the interfaces relevant to the business model. This DIN Specification has been initiated from the research project "Standards für wohnungsbegleitende Dienstleistungen im Kontext des demografischen Wandels und der Potenziale der Mikrosystemtechnik - STADIWAMI" ("Specifications for home services in the context of demographic change and the potential for microsystem technology - STADIWAMI"). The project (project number: 01FC08013 - 01FC08018, 01FC10006) is supported by the German Federal Ministry of Education and Research (BMBF) in the framework of the initiative "Technologie und Dienstleistungen im demografischen Wandel" ("Technology and services in demographic change").
