Abstract

The OpenCms 7 Content Relation Engine (CRE) is one of the most important improvements of OpenCms compared to previous versions. The CRE allows OpenCms to easily and efficiently track any kind of relations between two resources in the OpenCms Virtual File System (VFS).

In this session we will quickly review the obvious usages of this feature in the OpenCms workplace, like link validations during deletion or publishing or XML content edition, as well as new derivated features, like the possibility to publish resources together with all their related resources, or the categorization of resources.

We will then focus on more advanced usages, like XML content options to set the type of a relation or how to treat broken relations, as well as using the %(link) macro in JSP files to ensure consistent JSP file generation after changes in included files.

At the end we will see how to create and use user defined relation types, and take a quick look to the most important implementation details.
