Entire value chains consisting of powerful business alliance partners will compete as single entities { ecosystems { for customers. This r...

We propose a novel scheme to provide interoperability between two of the most widely discussed identity management systems, namely CardSpace and OpenID. In this scheme, CardSpace users are able to obtain an assertion token from an OpenID-enabled identity provider, the contents of which can be processed by a CardSpace-enabled relying party. The scheme, based on a browser extension, is transparen...

Today, a promising approach to large-scale interoperability in geographic information systems (GIS) is a GIS implemented via a distributed object management system (DOMS) (e.g. CORBA, Java, OLE/COM) based on a standardized spatial object model (e.g. OGIS [1]). Geographic entities are available as locationand platform-independent objects, and are accessible via their interface, i.e. their attrib...

Whilst the growing number of identity management systems have the potential to reduce the threat of identity attacks, major deployment problems remain because of the lack of interoperability between such systems. In this paper we propose a simple, novel scheme to provide interoperability between two of the most widely discussed identity systems, namely CardSpace and Shibboleth. In this scheme, ...

One of the important advantages of the object-oriented design and development methodology is the ability to reuse existing software modules. However the introduction of many programming languages with different syntax, semantics and/or paradigms has created the need for a consistent inter-language interoperability support framework. We present a brief overview of the most characteristic interop...

We discuss the impact of locally implemented behavi0ur in a federation of object-oriented databases. In particular, given a specification of an integrated view of a number of component databases, we discuss the process of determining the global methods that are implicitly implemented by a given set of local methods on these component databases. To this end, we develop the notions of objectivity...

The evolution of today’s markets and the high volatility of business requirements put an increasing emphasis on the ability for systems to accommodate the changes required by new organizational needs while maintaining security objectives satisfiability. This is all the more true in case of collaboration and interoperability between different organizations and thus between their information syst...
