This is a step by step case study of the site I built for Cambridge University to provide custom search and reporting on a large set of data. It includes building a component (with component creator) to handle editing.

Trying to use as few extensions as possible - Sigrid will show you what you can do "just with Joomla". She will start with showing a simple seminar/event calender and continue with the community features. Everything will be built without extensions. Keeping the number of extensions as low as possible helps you updating your system easily and therefore keeps security risks low.
This session reports on findings from an ongoing PhD project that looks at Joomla and its community from a management perspective. In short, this work explores configurations of stakeholder interests, governance dimensions (e.g. direction and coordination of community activities), community identity, as well as pricing and bundling strategies pursued by extension providers.
The intention is to encourage an exchange of ideas concerning the current work in progress of this project.
