Welcome to vieW4


vieW4 ("vienna World Wide Web Workgroups") is a web based framework that makes it easy for large workgroups to work together in a networked environment. A lot of powerful tools give the members of the group the required assistance for project-oriented and distributed working. vieW4 is based on the open source software Zope wich was customized to fit our in-house needs. The primary goal was to create a versatile solution incorporating all the essentials of group-oriented working in one simply-to-use application. vieW4 integrates and links documents in various file formats, projects, appointments, email communication and more and acts as a replacement for existing office based solutions.

Within user-defined workgroups, tasks can be defined, created and assigned to workgroup members. Tasks can then be prioritized and tracked to avoid missing deadlines. Project-related documents can be created, edited, changed and versionized. These documents are shared within a workgroup and each member can access them and discuss them with other members. Modifications of tasks, projects or documents are reproduceable and can be announced through mailing lists on request.

vieW4 is part of an expandable platform which also allows for the integration of a content management system (CMS). In later releases we are planning to merge both "workgrouping" (vieW4) and CMS to represent the whole live cycle from creation to publication and beyond of documents and objects evolving from group working.
