Agents, which are more or less autonomous programs performing tasks on behalf of users, act by exchange of messages. The content of messages is regulated by agreements called ontologies among the interoperating parties. In order for interoperation involving complex objects to be successful, there are several meta-ontological requirements, notably the ability to identify the object in the approp...

Several approaches for data interoperation identified by Karp have been implemented for biological databases. We extend Karp’s approach for interoperation not only to protein databases but also to knowledge bases and other information sources. This paper outlines algebra for protein data source composition based on our existing work of Protein Ontology (PO). In this paper we consider the case o...

The paper outlines a method for writing applications operating on components that are linked in a decentralised fashion. Our aspiration is to simplify data integration and system interoperation at scale. In projects we have routinely encountered obstacles for integration and interoperation due to architectural mismatches along several dimensions: network protocol, data format and data semantics...

Advanced sensors on board satellites offer detailed Earth observations. A workflow is one approach for designing, implementing and constructing a flexible and live link between these sensors’ resources and users. It can coordinate, organize and aggregate the distributed sensor Web services to meet the requirement of a complex Earth observation scenario. A RESTFul based workflow interoperation m...

Our society is digital: industry, science, governance, and individuals depend, often transparently, on the interoperation of large numbers of distributed computer systems. Although the society takes them almost for granted, these computer ecosystems are not available for all, may not be affordable for long, and raise numerous other research chal-

Given the many advances in modeling and simulation in the last decades, the need for a widely accepted framework and theoretical foundation is becoming increasingly necessary. Methods of modeling and simulation are fragmented across disciplines making it difficult to re-use ideas from other disciplines and work collaboratively in multidisciplinary teams. Model building and simulation is becomin...

3. Technology We demonstrate a prototype toolkit called ITSE (Integrated Translation Support Environment), for interoperation and migration of heterogeneous database systems. Semantic Metamodel Major datamodels (network, relational, object-oriented) are represented in the metamodel as sets of logic predicates alon,g with mapping rules to establish equivalences between expressions in different m...

Component-oriented software development is the design and development of software systems in a compositional way, i.e., the creation of a set of components that are supposed to work together in some way. Components are not designed in isolation but rather are meant to collaborate. Technically speaking, component-oriented software development is the integration of computational and compositional...

Solving domain mismatch and schema mismatch problems with an object-oriented database programming language. 27 Much research remains to be done. First, we have focused on three components of the mediation architecture, namely t...
