# Knowledge Sharing

QName: `f:knowledge-sharing`

Used to tag an _association_ to indicate that it "shares knowledge" between a source node and a target node. The source node is a "knowledge space" and the target node is a "knowledge recipient".

An association marked with `f:sharing-knowledge` will be considered to be an association that knowledge properties may propagate down when changes are made to a knowledge space node.

By default, the `a:child` association which is used to mark relationships between parent folder nodes and child folder or file nodes has the `f:sharing-knowledge` feature. As such, if you create a parent folder and give it the `f:knowledge-space` feature and knowledge properties, those properties will automatically propagate down your `a:child` associations.

As a result, knowledge properties from the parent folder will be pushed down onto the folder's children. In turn, the folder's children will be marked with the `f:knowledge-recipient` feature.

In many cases, you won't have to do much with the `f:sharing-knowledge` feature since in many cases you'll find that the `a:child` association type is what you intend to use. The knowledge space capabilities of Cloud CMS work innately with folders and files and so that'll probably cover most of what you need.

However, if you decide that you'd like to use knowledge space capabilities across other kinds of associations within your content model, you are free to do so. Just make sure that your modeled association types have the `f:sharing-knowledge` feature applied to them.

In addition, make sure that your custom association or association types are marked as `f:non-cyclic`. This is to prevent cases where propagated properties end up looping back and spinning into a loop. Cloud CMS will block your attempt to mark associations as `f:knowledge-sharing` unless they are also marked as non-cyclic.
