A knowledge-based framework for measuring organizational readiness for the adoption of B2B integration systems
Abstract: Organizational readiness has long been identified as ...more
a critical success factor for the adoption of inter-organizational systems. This article presents a knowledge-based methodology for constructing readiness assessment instruments for B2B integration solutions and examines its validation by conducting structural equation modeling analysis with input data from wholesale trading firms in Greece. Strong emphasis is given to the usability and appropriateness of the produced indicators and the relevant gap in literature is addressed. The B2Bi success factors that are presented and the final set of their underlying indicators can provide a starting point for conducting organizational readiness evaluations for the successful adoption of multi-enterprise integration solutions. Our methodology and findings can assist enterprises and public bodies to utilize, share, and enrich a knowledge base about B2Bi organizational readiness, throughout their evolution as part of the Knowledge Society.

Effects of Enterprise Interoperability on Integration Efforts in Supply Chains
Abstract: Despite their business value and return on investment, ...more
multi-enterprise integration projects are unbearably costly for many companies. With a view to realizing lower integration costs and resources, enterprises are seeking partner attributes that display the ease of B2B collaboration. This paper examines the relationship of B2B interoperability to integration effort. It breaks down enterprise interoperability into five layers (network, data, process, application, business) and investigates the particularity and effect of each. The research model is validated by a field study using data from 239 firms. Interoperability at the business, process, and data levels is found to be significantly but negatively associated with integration efforts. Interoperability at the application level showed little relation to integration efforts, and interoperability at the network level had a nonsignificant positive relationship with integration efforts. The research model and findings are a starting point for assessing interoperability with a potential partner at each layer and for estimating the involved integration effort, with a view to aiding e-partnership decisions and B2B integration management.

Business to Business Interoperability: A Current Review of XML Data Integration Standards, Computer Standards & Interfaces
Abstract: Despite the dawn of the XML era, semantic interoperability ...more
issues still remain unsolved. As various initiatives trying to address how the underlying business information should be modelled, named and structured are being realised throughout the world, the importance of moving towards a holistic approach in eBusiness magnifies. In this paper, an attempt to clarify between the standards prevailing in the area is performed and the XML Data Standards providing generic XML Schemas are presented. Based on this “XML Data Standards Map”, a multi-faceted classification mechanism is proposed, leading to an extensible taxonomy of standards. A set of facets is analyzed for each standard, allowing for their classification based on their scope, completeness, compatibility with other standards, openness, ability to modify the schemas and maturity, to name a few. Through populating and querying this multi-faceted classification, a common understanding of Data Integration Standards can be ensured and the choice of a standard according to the requirements of each business can be systematically addressed.

A Core Component-based Modelling Approach for Achieving e-Business Semantics Interoperability
Abstract: The adoption of advanced integration technologies that ...more
enable private and public organizations to seamlessly execute their business transactions electronically is still relatively low, especially among governmental bodies and Small and Medium-sized Enterprises (SMEs). Current solutions often lack a common understanding of the underlying business document semantics and most existing approaches are not able to cope with the huge variety of business document formats, stemming from highly diverse requirements of the different stakeholders. Developed and applied in the course of the EU-funded research project GENESIS, this paper presents a comprehensive core component-based business document modelling approach that builds upon existing standards such as the OASIS Universal Business Language (UBL) and the UN/CEFACT Core Component Technical Specification (CCTS). These standards are extended by introducing the concept of generic business document templates out of which specific documents can be derived according to the actual user’s needs. Key principle to achieve this flexibility is the integration of business context information that allows for modeling standard-based but at the same time customized business documents. The resulting modelling framework ranges from (tool-supported) graphical data models to the technical representation of the business documents as XML schema documents designed in compliance with the UN/CEFACT XML schema Naming and Design Rules (NDR).

Achieving Cross-Country Electronic Documents Interoperability with the help of a CCTS-based Modeling Framework
Abstract: The dawn of the XML era appears insufficient to guarantee ...more
a holistic approach in electronic transactions, as long as the semantics confusion, the lack of a common understanding of the underlying data and the business standards dilemma prevail and prevent data interoperability issues from being resolved. As various e-Government initiatives are being realized throughout the world, an imperative need for creating unified governmental data models that will facilitate the seamless exchange of information and the deployment of interoperable systems in Enterprises and Central, Regional and Municipal Government emerges. After attempting to identify relevant research that has been undertaken in the field of data modeling, the present paper analyzes the scope and the objectives of the business information modeling oriented towards governmental data. Based on UBL (Universal Business Language) and CCTS (Core Components Technical Specification), a component-based data modeling methodology enhancing business-to-government interoperability is proposed, creating the basis for a repository of governmental data models. The approach adopted may also serve as guidelines for creating and transitioning between "generic - harmonized" and "specific - contextualized" documents. A real world paradigm extracted from the Periodic VAT Statement document finally comes to prove the soundness of the proposed methodology.
