Abstract
A core piece of work in IMPACT lies in the development of novel software techniques for a number of tasks connected to Optical Character Recognition (OCR), such as image enhancement, segmentation and postprocessing, as well as in the improvement of existing OCR engines and experimental prototypes. The variety of platforms used by the developers of these tools makes it necessary to define an overall technical architecture for establishing interoperability of the various software components. The notion of interoperability that has been pursued in IMPACT is defined by ISO/IEC 2382-01, Information Technology Vocabulary, Fundamental Terms, as: “The capability to communicate, execute programs, or transfer data among various functional units in a manner that requires the user to have little or no knowledge of the unique characteristics of those units.” Accordingly, the concept of interoperability in IMPACT is aimed towards the implementation of a highly flexible and easy to use technical framework and the integration of the software components within that framework. Interoperability of all tools as a main principle is herein achieved through two abstraction layers: individual software tools will be wrapped as web services, which are then again wrapped in a so called “basic” workflow module. Web services are provided by describing the publicly available interfaces of the service using the Web Service Description Language (WSDL), and by using Simple Object Access Protocol (SOAP) for data exchange. Basic workflows are provided by wrapping the web services and their documented in- and outputs in a dataflow description used by the Taverna workflow management system, thereby exposing relevant features of the software tools in the form of ready-to-use components. The main advantages of this approach are the guaranteed compatibility of the tools offered as web services – avoiding incompatibility issues between different web service frameworks – and the reusability of a web service implementation. This report is basically divided into two major sections: the first one will detail the current status of work on the Interoperability Framework architecture, the software components it has been built from and the functionality it provides, whereas the second section will be describing how each of the tools and applications developed by IMPACT partners are envisaged to be integrated with the Interoperability Framework, thereby enabling interaction and data exchange between them.
