Unified Data Modelling and Document Standardization Using Core Components Technical Specification for Electronic Government Applications

Unified Data Modelling and Document Standardization Using Core Components Technical Specification for Electronic Government Applications

In the effort of Governments worldwide to effectively transform manual into electronic services, semantic interoperability issues pose as a key challenge: system-to-system interaction asks for standardized data definitions, codification of existing unstructured information and a framework for managing governmental data in a unified way. Integrating and extending recent developments in Germany, ...

Conceptual Business Document Modeling using UN/CEFACT's Core Components

Before two businesses can engage in a business-tobusiness process an agreement about the process execution order and the business documents exchanged in the collaborative process must be found. Although several initiatives from different industries have started standardization initiatives for business documents a set of shortcomings still remain: (1) the different standards do not have a common...

Components, Contracts, and Connectors for the Unified Modelling Language UML

The lack of a component concept for the UML is widely acknowledged. Contracts between components can be the starting point for introducing components and component interconnections. Contracts between service providers and service users are formulated based on abstractions of action and operation behaviour using the preand postcondition technique. A valid contract allows to establish an intercon...

Unified specification of control and data flow

Many signal processing systems use event driven mechanisms typically based on nite state machines (FSMs) to control the operation of computationally intensive (data ow) parts. The state machines in turn are often fueled by external inputs as well as by feedback from the signal processing portions of the system. Packet-based transmission systems are a good example for such a close interaction be...
