2. Susanne Guth, Gustaf Neumann, Mark Strembeck - Virtual Goods, Ilmenau/Germany, 2003 Toward a Conceptual Framework for Digital Contract Composition and Fulfillment Agenda Motivate the need of a conceptual framework for the composition and fulfillment of digital contracts The contract life cycle: An overview 1.offer creation 2.offer confirmation/conclusion of contract 3.fulfillment of duties/execution of rights 4.archiving Contract content and usage Phase 1 & 2: Scenario specific contract composition Phase 3: Execution of rights via electronic tickets Conclusion and future work
