Open ServicesService versus Web service Aggregates, structures and configures people, resources, and information to create new value for consumers.Social process Firms, groups and individuals (i.e. the community) are equal participants which freely cooperate to provide information on services.Self-governance Service are common good which the community tries to create by using forms of decision-making and autonomy that are widely distributed.Openness and free-access The services created, being the elements of value created by the community, are freely accessible on a universal basis.Autonomy and distribution The participants of the community have the autonomy to advertise their know-how, capabilities and skills in the form of services to the world.Semantic services Services are said to be semantic since they explicitly describe their services using a conceptual or domain model, shared vocabularies.2012Information Systems Management[CPL+2012] Cardoso, J.; Pedrinaci, C.; Leidig, T.; Rupino, P. and Leenheer, P.

Later renamed to a-USDL (pronounced alpha-USDL). http://www.genssiz.org/research/service-modeling/alpha-usdl/ USDL/2011 A W3C Incubator group was created USDL was adapted andextended based on industry feedback at the end of 2011. http://www.w3.org/2005/Incubator/usdl/ Linked-USDL/-- In order to make the specification gain a wider acceptance, a versioncalled Linked-USDL emerged using Semantic Web principles Iitsdevelopment is still in progress. http://linked-usdl.org/[CBM+2010] Cardoso, J.; Barros, A.; May, N. and Kylau, U.
