CentraSite offers you the possibility to add computed attributes into asset type definitions and profiles; this allows you to define attributes which require complex computation in Java and then implement them as a Java plug-in, thus overcoming the limitations of predefined attribute types. You could, for example, make attribute values localizable by using computed attributes.

A computed attribute must describe its scale for the rendering within the profile of the asset type.

For a Java-based plug-in for a computed attribute, you create a jar file that contains the plug-in definition and you load the jar file via CentraSite Control into the repository.

After you have added a computed attribute into a profile definition, you can perform administration tasks on the computed attribute in the same way as for normal attributes. For example, you can define the ordering of the attributes in a profile, regardless of whether they are standard attributes or computed attributes.
