In Internet applications, Web object prefetching is a commonly used and quite effective algorithmic approach to reduce user perceived delays. While a separate concept, prefetching is closely related to caching and the...

this paper describes our architecture-based approach to IT valuation. It sketches how different valuation methods can be combined and linked to models of business requirements and enterprise architecture, and how a first part of this approach is realized using Archi Mate and BiZZ design Architect. In this manner, the value and cost of different elements in the architecture can be computed and attributed to the various goals of the organization.

Modeling high-level enterprise strategies helps clarify the intentional dependencies between the organizational actors. Business process models, on the other hand, give more elaborated descriptions to the enterprise daily operations. In this paper, we aim to synthesize these two modeling perspectives by synthesizing the i* model and the UML activity diagram.

the paper shows how to describe the semantics of domain-specific enterprise and information system (IS) modelling languages using the Unified enterprise Modelling Language (UEML). the approach is illustrated with a fragment of a domain-specific modelling language based on the new ISO 15926 standard for data integration, sharing and hand-over between computer systems. the aim is to ensure that the semantics of new domain-specific languages (DSLs) can be quickly, easily and precisely defined in relation both to one another and to existing general-purpose languages.

In ODP, an enterprise specification is expressed in terms of the definition of some set of communities, characterized by their community contracts. A community places constraints on its members, restricting the behaviour they can participate in. this may involve a stronger form of constraint than those which result from the traditional binding of objects at interfaces, which requires only that the communication between the objects has some observable properties. this paper discusses the different forms of constraints, and examines the range of forms that community construction may take. In particular, it examines the process of abstracting from a community to yield a community object, and then using this object to fill some role in a broader community. It shows that the role filling process needs to consider mappings and constraints between objects that fill other roles in the communities concerned.

In this paper we propose a typed approach to business process specification based on typed workflow charts. these can be exploited as a domain-specific programming language and facilitate tight integration between workflow definition and system dialogue programming. the approach also supports the integration of business process modeling and business process automation. We discuss two ways of exploiting this potential for integration, one is the design of an integrated business process management suite and the other is a software artifact tracker based on a view-based, multi-dimensional software modeling tool.

Service-Oriented enterprise Architecture requires the efficient development of loosely-coupled and interoperable sets of services. Existing design approaches do not always take full advantage of the value and importance of the engineering invested in existing legacy systems. this paper proposes an approach to define the key services from such legacy systems effectively. the approach focuses on identifying these services based on a Model-Driven Architecture approach supported by guidelines over a wide range of possible service types.

Service as part of an enterprise architecture are more and more seen as a paradigm supporting the co-creation of value between a service provider and an actively involved prosumer. Following this view, service consists both of a primary interaction providing the core service and secondary interactions supporting the co-creation of value. Meta-services conceptualize such secondary interactions between service providers and service consumers in service-oriented enterprise architectures. Meta-services influence the lifecycle status of services by designing, deploying or retiring services. Furthermore they capture functionality to modify or evaluate services. Finally, meta-services are used to flag inadequate service quality to the service provider.

this paper reviews the support for the goal domain in several enterprise modelling approaches and enterprise architecture frameworks, namely, ARIS, ISO RM-ODP enterprise Language, DoDAF, MODAF, BPMN/BMM, ArchiMate and its ARMOR extension. We describe how these efforts propose to align goals withthe remaining elements in enterprise architectures (with special attention to the alignment of goals and business processes). Our aims are twofold: (i) to provide an integrated overview of the support for goal-related concepts in existing enterprise modelling approaches of and, (ii) provide guidance for the selection of the frameworks with respect to the support for goal-related concepts.
