Manage asset relations

Depending on your CELUM Content server's configuration, there can be various types of relations with different prerequisites for creating them. Out-of-the-box, only the "Language variant" relation type is available and will be used as an example case in this topic.

Relations can also have different statuses, depending on the availability of the related asset:

Broken relations are relations that were established to a now deleted asset. If asset A is related to asset B and asset B is deleted, then the relation to it will be shown as broken in asset A's detail view. Broken relations are marked with the icon and the deleted asset's preview and name are removed from the detail view tab.

Relations with outdated versions are relations that were established to an earlier version of the related asset. If asset C is related to version 2 of asset D and asset D gets a new version (version 3), then the relation to it will be shown as outdated in asset C's detail view. In asset D's detail view, all established relations are removed, because relations are always tied to a specific asset version. Outdated versions are marked with the icon.

Create an asset relation in the Explore View

You create relations directly in the asset list or lightbox, either via drag and drop or with the "Create relation" action in the context menu or magic menu.

For using the "Create relation" action, select exactly two assets in the asset list or lightbox.

In this section, only the drag and drop method is explained in detail:

Select an asset, for example the "ContentHub_User_Guide_Nova_EN.pdf" asset.
Drag and drop the asset with your mouse onto another asset within the same collection, for example the "ContentHub_User_Guide_Nova_DE.pdf" asset. The Asset Relation dialog opens.

You can create relations between assets in different collections as well. Simply select a parent collection or "All assets" in the tree and enable the "Show content of child collections" check-box in the content bar. Then you can drag any asset onto another asset.
In the top section of the Asset Relation dialog, you see the previews of the two affected assets on either side with information about the relation type and direction between them:

The asset which you dragged and dropped is always displayed on the left side (as asset A).
Choose a relation type from the drop-down menu. In this example, the type is set to "Language Variant"
Choose the relation direction. In this example, the chosen direction reads as follows: "ContentHub_User_Guide_Nova_EN.pdf" (asset A) has a language variant "ContentHub_User_Guide_Nova_DE.pdf" (asset B).
Set the relation's information fields. In this example, there is only one optional field, but your custom relations may include other fields.
Save the dialog with "Confirm".

In the related assets' "Asset relations" detail view tab, you can view the established relations.

Create an asset relation in the compare view

When comparing 2 assets, you can create a relation between them:

In the compare view, open the context menu for one of the assets.
In the context menu, click "Create relation".
The Asset Relation dialog opens and you can configure the relation as described above.

Delete an asset relation

Open the detail view for an asset and go to the "Asset relations" tab.

Click the "Delete asset relation" button in the asset relation panel's header.
The relation will be deleted immediately, but you can undo the action in a snackbar notification if you accidentally deleted it:

The two assets which were related are not affected by this action at all. Just the relation between them is removed.

Why are some relations shown as broken?

As described in the above explanation section, a relation becomes broken if one of the related assets is deleted. The target (or source) of the relation is no longer in the system, so the relation is broken on the remaining asset.

Why is a relation no longer shown in a related asset's detail view?

The most likely explanation is that one of the related assets got a new version. Relations are always established on specific asset versions, so when a new version is uploaded, the relation is not automatically established for that new version. So, the updated asset does not have the relation in its detail view anymore.

Can I edit or update an existing relation?

No, you cannot update an existing relation (change the relation's information fields, source, or target). You can only delete an existing relation and then create another one with different values.
