| Abstract | Die Modellierung komplexer informationsverarbeitender Systeme erfolgt typischerweise durch Gliederung in voneinander unabhängige Einheiten, die über ihre Schnittstellen Meldungen austauschen. Deren Beschreibung wird heute hauptsächlich mit 2D-graphischen Werkzeugen durchgeführt. In diesem Beitrag identifizieren wir Probleme, wie sie bei der Modellierung solcher Systeme als Systeme kommunizierender sequentieller Prozesse (CSP) auftreten. CSP selbst, sowie GRAPES und Occam als CSP-Abkömmlinge sind dabei die Ausgangsbasis der Problemanalyse. Als Problemlösung schlagen wir eine 2D-graphische Prozeßsprache vor. Es wird außerdem das Werkzeug GRADE-3D beschrieben, welches die Diagramme der Prozeßsprache räumlich darstellt. Es verfügt über Funktionalität zur Interaktion mit der Darstellung, zur Analyse und Anzeige von Kommunikationsstrukturen sowie zur Modellbearbeitung. Es werden ferner Lösungen für typische Probleme von 3D-Werkzeugen vorgestellt. Den Abschluß bildet eine Bewertung der 3D-Werkzeuge unter den Aspekten Text vs. 2D vs. 3D sowie aus der Sicht von GRAPES-Modellierern. . Complex information processing systems are usually modelled by dividing them into independent units which then communicate through their interfaces. They are usually described using 2D-graphic tools. In this paper, we identify problems which emerge when communicating sequential processes (CSP) are used as the model system. CSP and its derivatives GRAPES and Occam are the starting point for this problem analysis. To resolve these problems we suggest a new 2D-graphic process language. We also describe the tool GRADE-3D, which presents the process language diagrams spatially; and processes functionality for interaction, for analysis and display of communication structure, as well as for model editing. Additionally, solutions for typical problems of 3D-tools are presented. Finally, 3D-tools are assessed from the perspectives of text vs. 2D vs. 3D and of GRAPES modellers. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
