“…In literature, different standards for describing EBDs based on the XML Schema language can be found. These standards can be divided into [21]: (1) standards schemas for messages, like cXML [9], and xCBL [35]; and (2) standards for defining both the processes and the associated message schemas, like RosettaNet [24], ebXML [34], and OAGIS [28].…”

“…Supposing that the partners decide to base their collaboration on the OAGIS [28] standard, the information of Table 1 can be interchanged between partners by using the ShipmentPlanningSchedule XML schema. This schema has an STO (STO EBD ) associated that describes its syntactic structure as explained in Section 4.1.…”

In order to support the execution of collaborative business processes, trading partners have to exchange electronic business documents. Since each partner has its own systems and culture, they could use different terms and metadata structures to represent their data, even when referring to the same domain of interest. Then, an appropriate approach for defining the semantics of these documents is required to achieve semantic interoperability. To this aim, a number of approaches have been proposed based on the use of a single domain ontology. These approaches imply the imposition of a global meaning of terms, which are used to represent the entities of a domain. This goes in opposition to one of the aims of trading partners, which is to participate in collaborative business processes without losing their autonomy and privacy. In this scenario, it is necessary to define a framework for allowing trading partners to exchange information without imposing a global meaning of it. In this paper, a novel approach is proposed in order to define the semantics of the electronic business documents interchanged between trading partners in a collaborative relationship. This approach is based on the idea of making some domain features, which are generally implicit, explicit in the domain ontologies. An application example of this approach is also presented.

The notion of context appears in computer science, as well as in several other disciplines, in various forms. In this paper, we present a general framework for representing the notion of context in information modeling. First, we define a context as a set of objects, within which each object has a set of names and possibly a reference: the reference of the object is another context which "hides" detailed information about the object. Then, we introduce the possibility of structuring the contents of a context through the traditional abstraction mechanisms, i.e. classification, generalization, and attribution. We show that, depending on the application, our notion of context can be used as an independent abstraction mechanism, either in an alternative or a complementary capacity with respect to the traditional abstraction mechanisms. We also study the interactions between contextualization and the traditional abstraction mechanisms, as well as the constraints that govern such interactions. Finally, we present a theory for contextualized information bases. The theory includes a set of validity constraints, a model theory, as well as a set of sound and complete inference rules. We show that our core theory can be easily extended to support embedding of particular information models in our contextualization framework.

“…3). In this example, the contexts are been generated with the purpose of resolving name ambiguities [14]. This is solved in other technologies with the namespace concept, which is a space (context) in which object names are unique.…”

Abstract. In the last years different proposals that integrate ontologies and contexts, taking advantages from their abilities for achieving information semantic interoperability, have arisen. Each of them has considered the problematic from different perspectives. Particularly, through an actual case study this paper shows which are the problems related to support information semantic interoperability between different parties involved in a collaborative business relation over the Internet. Furthermore, this paper analyzes those problems from previous proposals perspective and highlights the weaknesses and sti'engths of them.
