In this chapter, we explained how to install the Kaleo workflow plugin for Liferay EE. Liferay’s Kaleo workflow engine is included with Liferay CE. We discussed how to create new workflow definitions and examined the XML schema for them. We looked at how to choose different workflow processes for different asset types. We also explained how end-users can interact with the approval process. Finally, we discussed how to use workflow with different types of applications such as Documents and Media and Blogs, Wikis, and Message Boards. In the next chapter, we’ll look at Kaleo forms and the Kaleo workflow designer.
