Recently I’ve found a Wiki in SDN which I think has a great potential. First of all, you need to have a clear notion of the Wiki Concept. According to Wikipedia:

A wiki is a website that uses wiki software, allowing the easy creation and editing of any number of interlinked Web pages, using a simplified markup language or a WYSIWYG text editor, within the browser. Wikis are often used to create collaborative websites, to power community websites, for personal note taking, in corporate intranets, and in knowledge management systems.

Most wikis serve a specific purpose, and off topic material is promptly removed by the user community. Such is the case of the collaborative encyclopedia Wikipedia. In contrast, open purpose wikis accept all sorts of content without rigid rules as to how the content should be organized.

Being that said, there are numerous wikis sitting in SDN. And since ESS is a very hot topic, it is a good idea to highlight this one.

The “ESS Initial Steps” wiki was originally created by Stuart Campbell. The beauty of the wikis is that any interested user can edit the information on it, obviously with the objective of enriching it or completing it further. Note that for SAP SDN wikis you’ll need to have a valid SAP issued user to be able to edit and save the information in the wikis.

The “ESS Initial Steps” wiki intends to provide a hands-on initial contact with the ESS implementation. It starts of listing the core components information, links/urls to the SAP Help pages, the ESS architecture, the ESS Homepage Framework concept, and so on.

If you’re involved in Employee Self-Services and Portal projects, go along and visit this wiki. You can think about contributing and improving it.
