SAP Research RoofTop Marketplace

2009-04-20 , Hoyer, Volker , Gilles, Florian , Fleischmann, Kathrin , Dreiling, Alexander , Stanoevska-Slabeva, Katarina

Enterprise Mashups have gained momentum in the last years. Business users with no or limited programming skills are empowered to leverage in a collaborative manner existing mashable components. By combining and reusing Web-based resources within minutes, business users are able to create new value added applications to solve an individual and ad-hoc business problem. In this demo, we show the SAP Research RoofTop Marketplace prototype that transfers established marketplace concepts and principles to the Enterprise Mashup paradigm in order to handle business and organizational challenges of the Mashup paradigm in enterprise environments.

Towards a Reference Model for Grassroots Enterprise Mashup Environments

2009-06-08 , Hoyer, Volker , Stanoevska-Slabeva, Katarina , Newell, Susan

A new kind of Web-based application, known as Enterprise Mashups, has gained momentum in the last years: Business users with no or limited programming skills are empowered to leverage in a collaborative manner user friendly building blocks and to combine and reuse existing Web-based resources within minutes to new value added applications in order to solve an individual and ad-hoc business problem. Current discussions of the Mashup paradigm in the scientific community are limited on technical aspects. The collaboration and the peer production management aspects of the Mashup development have received less attention yet. In this paper, we propose a reference model for Enterprise Mashups which provides a foundation to develop and to analyse grassroots Enterprise Mashup environments from a managerial and collaborative perspective. By following the design science research approach, we investigate existing reference models and leverage the St. Gallen Media Reference Model (MRM). The development of Enterprise Mashups is structured by market transaction phases similar to electronic markets. The user roles, the necessary processes and the resulting services are modelled according to the views of the MRM. By means of the SAP Research RoofTop Marketplace prototype we demonstrate the application of the designed reference model for grassroots Enterprise Mashups environments.

Supporting Market Transactions through XML Contracting Container

2000-08-10 , Greunz, Markus , Schopp, Bend , Stanoevska-Slabeva, Katarina

Based on a Business Media Framework (BMF), this paper proposes an architecture for secure electronic contracts, which adhere to legal requirements and can be applied for an integrated management of market transactions. We propose the use of XML, digital signatures, and Java technology for secure electronic contracting. The resulting contract container can be applied for the support of an integrated information flow through the different services of an electronic market. In addition the container holds a control logic, that supports the management of the contract negotiation and the contract settlement. The concept provided in this paper was developed in the Secure Electronic Contracts (SeCo) project of the =mcminstitute of the University of St. Gallen and the University of Zurich, Switzerland, in cooperation with several business partners.
