A different approach: eZ Open Funding
The commercial Open Source CMS vendor eZ System have introduced an alternative to funding changes and customisations in their Open Source CMS eZ publish.
One of their customers needed a “content diff” function for eZ publish. This functionality would allow users to request an overview of changes between different versions of a content object. The historical time-line would be limited by the number of previous versions available for any given object and the differences between the selected versions would be displayed. This kind of functionality is essential in many quality management systems (QMS), as well as in other related areas.
Their customer suggested that other members of the eZ ecosystem might need the same functionality and are willing to share the costs of having the project done. Within a short space of time, three customers and two partners agreed to provide the required funding and the project was underway. This model of cooperation forms the basis of the eZ Open Funding initiative.
