	abstract = {Data-intensive information systems constitute the backbone of e-commerce and e-governance services running worldwide. Structured data is a central artefact in these information systems. Requirements for structure in data are typically modelled in a database schema. However, information system behaviour is often a function of interactions that cross-cut database features such as field values in different tables. For instance, consultants at the Norwegian Customs and Excise reveal that taxation rules are triggered due to data interactions between 10,000 items, 88 country groups, and 934 tax codes. There are about 12.9 trillion possible three-wise interactions of which only about 220,000 interactions are used in reality as customs rules. Therefore, we ask, how can we model data interaction requirements to further bound the input domain of an information system? In this position paper, we address this question by modelling data interaction requirements using classification tree models. We also present different applications of data interaction requirements in the development of information systems.},

	abstract = {In domains such as automotive, avionics, and railway, critical systems must comply with safety standards to allow their operation in a given context. Safety compliance can be an extremely demanding activity as practitioners have to show fulfilment of the safety criteria specified in the standards and thus that a system can be deemed safe. This is usually both costly and time consuming, and becomes even more challenging when, for instance, a system changes or aims to be reused in another project or domain. This paper presents SafetyMet, a metamodel for safety standards targeted at facilitating safety compliance. The metamodel consists of entities and relationships that abstract concepts common to different safety standards from different domains. Its use can help practitioners to show how they have followed the recommendations of a standard, and particularly in evolutionary or cross-domain scenarios. We discuss the benefits of the use of the metamodel, its limitations, and open issues in order to clearly present the aspects of safety compliance that are facilitated and those that are not addressed.},
