Several model driven approaches are currently used and developed, namely, generic model driven approaches, agile model driven approaches, business process model driven approaches, etc. This paper proposes the model driven approach, which is based on a two-hemisphere model. The twohemisphere model integrates application and problem domain issues. The model utilizes automatic model transformations, but in the same time allows room for input of tacit knowledge. It is a practice-oriented approach which ties together methods of business process modeling, object oriented, and model transformation approaches in order to support cognitive needs of requirements holders and object oriented software developers, and provide framework for explicit and transparent representation of mutually related business and software development knowledge. It utilizes tacit knowledge of stakeholders (including software designers), but in the same time reflects this knowledge in explicit and automatically reconfigurable models that form the basis for automatic code generation.

Open Data is considered a key to scientific innovations. These freely available datasets can also be used as a foundation to enhance the digital and data literacies among the younger generation of school pupils. This article presents the design and prototype of an Open Data web interface based on the Enterprise Architecture Oriented Requirements Engineering (EAORE) approach for Open Data usage as an educational resource in Danish public schools. We first systematically review the literature on Open Data use in educational fields and selected 14 research articles with a particular focus on the use of Open Data in the educational domain after prescribing an inclusion/exclusion criteria on 101 research articles identified initially. The review indicates that there is a gap between Open Data opportunities within the educational domain and in exploring the use of Open Data as a source to develop twenty-first-century skills, specifically digital and data literacies among younger school pupils. To fill this gap, we propose an EAORE approach that represents how Enterprise Architecture (EA) models can guide the overall Requirements Engineering (RE) process for the use of Open Data in Danish public schools. Based on these EA models, we designed the prototype of an Open Data web interface for schools.

Abstract. The paper focuses on the use of the fractal paradigm in enterprise modeling. It investigates whether the properties of fractal organizations can be applied in business analysis and whether this results in useful outcomes and new insights. Based on an adaptation and operationalization of properties of fractal organizations, two real-world cases are analyzed using the adapted properties. The contributions of this paper are (1) to adapt fractal organisation properties for use in analysis of enterprise models, (2) to present practical examples from two cases showing the application of the fractal organisation properties, and (3) to identify potentials and limitations of using fractal organisation perspective in enterprise model analysis.

Virtualization has enabled the commoditization of cloud computing, as the hardware resources have become available to run different environments and share computing resources amongst different enterprises. Two technology types are commonly used in virtualization of hardware, namely, hypervisor and container. The present paper concerns only container technologies. A comprehensive overview of the container technologies for virtualization and the dynamics of their popularity have not been available yet. Without such an overview, the informed fast choice of technologies is hindered. To fill this knowledge gap, a systemic literature review was conducted to reveal the most popular container technologies and the trends in their research.

Open Data has been considered as a key to scientific innovations. These openly licensed data-sets can be accessed, used, rebuild, and shared by anyone and anywhere. Mostly, Open Data is discussed in relation to its production, storage, licensing and accessibility, but less often -in relation to its practical subsequent uses, e.g. as an educational resource. In general, Open Data can be used as an open educational resource to develop transversal skills among school students. This paper presents an Enterprise Architecture Oriented Requirements Engineering (EAORE) approach for Open Data usage as an educational resource in Danish public schools. The aim of this research work is to identify requirements of Danish public schools for the development of an Open Data interface. The EAORE approach represents how Enterprise Architecture (EA) models guide overall Requirements Engineering (RE) process for Open Data usage in Danish public schools.

We address the existing gaps between business process models, enterprise architecture (EA) models and, external regulations that hinder completeness and lawfulness of business process models. As a solution we propose a high-level architecture for business process knowledge management that bridges the identified gaps. We use de-facto industry standards for modelling business processes and EA-BPMN and ArchiMate. We propose to use Bunge-Wand-Weber (BWW) model as a theoretical foundation for storing business process knowledge represented in BPMN and ArchiMate models and storing elements that address lawfulness of the models. BWW model provides a framework for systematically storing internally maintained process knowledge (models) and externally maintained knowledge (regulations), and supporting completeness and lawfulness of the models. Thus, the main contributions of our approach is supporting completeness and lawfulness of business process models and supporting the creation of information services to increase efficiency in the business process modelling context.
