Define a reference engine usable by Silva content

Project description


silva.core.references is a core Silva extension that defines directed references between two Silva content: a source and target. With the help of a central catalog, you have the possibility to query the references in both direction: who is the target if I am the source, and who is the source if I am the target.

References are tagged with different names, and can be found by searching on one of those names.

Unless you use weak references, you can’t remove an content which is a target of a reference, you will get an error. If you used a weak reference, the source will be removed.

This extension provides you with a set of fields and widgets that can be used in forms (zeam.form and Formulator) in SMI.


This extension is used to manage links and relations in Silva Document, Silva Ghost and Silva Link for instance.
