A Client-Server Model for Editing ODF Documents on Mobile Devices

Open Document Format (ODF) is a popular office document format accepted by most of modern desktop office suites. The aim of our project is to create a software suite of specialized mobile ODF schemata and editors to provide support of editing ODF-based documents on mobile devices. Number of tests have been carried out with prototype tools focusing on the resource need of transferring, visualizing and editing simple ODF documents. Based on test results we have found that the limited capacity of mobile devices (compared to desktop computers) implies that documents in their original form cannot be handled on mobile devices. In this paper we investigate the methods and background of ODF-based document transfer and edition in a client-server model

Concept and Architecture of a Distributed Object-Oriented Database Kernel

In this paper we describe the distributed objectoriented database kernel OMS (Object Management System), developed at CADLAB and used within the Jessi Common Framework (JCF 1 ). This kernel provides a flexible, high-performance base for today's applications like design environments, office automation, or multimedia systems. We shortly describe the internal data model (IDM) and then turn to the main topic of the paper, the distributed architecture of the OMS, where we deal with the process model, the storage of data, caching, transactions, and the eventtrigger mechanism. CADLAB is a Cooperation of the University of Paderborn and Siemens Nixdorf Information Systems AG 1 JCF is supported by the European Community as ESPRIT project number 7364 1 Introduction In the recent years, a number of new and demanding application areas for database management systems (DBMS) have evolved (CAX 2 , Office Automation, Knowledge Representation, Multimedia etc.). For those applications, conventi..
