This paper contains a report on a selection of recent research projects carried out at the Institute for Mechanics of Materials and Structures of Vienna University of Technology. The aim of this report is to demonstrate that Computational Mechanics of Materials and Structures is a scientific field with many characteristics of an electronic golem.
Choreography modeling and service integration received a lot of attention in the last decade. However, most real-world implementations of inter-organizational systems are still realized by traditional Electronic Data Interchange (EDI) standards. In traditional EDI standards, the notion of process or choreography is not explicitly specified. Rather, every(More)
With the raising significance of electronic commerce and e-government applications the need for standardized business documents has emerged. Today, a business partner seeking to implement a new electronic commerce solution may choose from a multitude of different standards. Most of the standards are domain-specific and thus heterogeneous, since standards(More)
Traditional standards for Electronic Data Interchange (EDI), such as EDIFACT and ANSI X12, have been employed in Business-toBusiness (B2B) e-commerce for decades. Due to their wide industry coverage and long-standing establishment, they will presumably continue to play an important role for some time. EDI systems are typically not “process-aware”, i.e.,(More)
Inter-organizational relationships (IORs) are important for creating business potential and increasing business performance. The evaluation of IORs is necessary for analyzing the collaboration between businesses as well as for assessing business partners. However, the evaluation of IORs is ambiguous since it is usually measured by success factors, such as(More)
Standardized business documents are a prerequisite for Electronic Data Interchange (EDI). One predominant standards family are the Electronic Data Interchange For Administration, Commerce and Transport (EDIFACT) formats created and maintained by the United Nations Centre for Trade Facilitation and Electronic Business. However, EDIFACT formats are currently(More)
Exchanging structured business documents is inevitable for successful collaboration in electronic commerce. A prerequisite, for fostering the interoperability between business partners utilizing different business document standards, is a mapping between different standards. However, the effort involved in creating those mappings is hard to estimate. For(More)
Organizations exchange data electronically to perform business transactions using Electronic Data Interchange (EDI). In order to gain insights on such transactions, approaches for inter-organizational business process mining based on the observation of exchanged EDI messages have been recently proposed. In recent approaches, however, only meta-information(More)
The United Nations Centre for Trade Facilitation and eBusiness (UN/CEFACT) standardizes business documents for electronic data interchange. Their approaches towards UN/EDIFACT and XML have later been followed by a conceptual modeling approach called Core Components (CC). Having used this approach for four years in practice, it became evident that the(More)
