“…The fact type 'role can subscribe to event type in context of activity type' expresses the visibility of events to agents in the context of an activity. It does not express how agents are notified of the event, which can generally occur using either a pull, a push or a publish-subscribe mechanism (Bailey et al, 2005). Furthermore, it is possible that the visibility is constrained by so-called event subscription constraint business rules.…”

In management theory of the last decades, much importance has been attached to a process-oriented perspective on organizational (re)structuring. Yet to date, organizations still experience difficulties in applying this process-oriented perspective to the design and maintenance information systems. The root of the problem lies with a procedural representation of business processes that contains inadequate information for computer systems to provide flexible automated business process support. The counterpart of a procedural representation is a declarative one that explicitly takes into account the business concerns that govern business processes. Recently, a number of process modeling languages have appeared that could be identified as declarative languages. These modeling languages have very distinct knowledge representation backgrounds, often lack a formal execution model and often only model one aspect of the many business concerns that exist in reality. What is needed are meaningful ways to combine several kinds of expressions, called business rule types, independently of the used methods for knowledge representation and reasoning. In this paper, we present the EM-BrA 2 CE (Enterprise Modeling using Business Rules, Agents, Activities, Concepts and Events) Framework, a unifying vocabulary and execution model for declarative process modeling. The vocabulary is described in terms of the Semantics for Business Vocabulary and Rules (SBVR) standard and the execution model is presented as a Colored Petri Net (CP-Net). In addition, we show how declarative process models can contribute to the model-driven design of Service-Oriented Architectures.

This article discusses forms of reasoning (beyond ontology reasoning), and reasoning languages (beyond ontology languages), that are needed for a full deployment of the Semantic Web. We first outline a motivating application scenario, then discuss the logic languages needed on the Semantic Web and related issues. The views reported about in this article underly and have been developed within the EU research project REWERSE (REasoning on the WEb with Rules and SEmantics, cf. http://rewerse.net).

“…Recently some reactive languages have been proposed, that allow for updating Web data and are capable of reacting-to some forms of events, evaluate conditions, and upon that act by updating data [7,5,15,8,4] The common aspect of all of these languages is the use of EventCondition-Action (ECA) declarative rules for specifying reactivity and evolution. Such kind of rules (also known as triggers, active rules, or reactive rules), that have been widely used in other fields (e.g.…”

“…Regarding the former, except for [8,4], the languages above only deal with atomic events, where these are either incoming messages or (implicit) changes of XML or RDF data. In this respect, there is some preliminary work on composite events in the Web [6], but that only considers composition of events of modification of XML-data in a single document.…”
