# Relation Marker

![No UI](https://img.shields.io/static/v1?label=UI&message=none&color=inactive)

The "Relation Marker" plugin marks two assets with a nodereference field related to the relationship type of the two assets

## Properties

To be configured in *{home}/appserver/conf/custom.properties*.

##### relationMarker.license

> type: String, **required: yes**, since 1.1, default: -

License key (delivered by brix Solutions AG).

##### relationMarker.nodereferenceFieldId

> type: long, **required: yes**, default: -

The nodereference field for tagging the asset. It must be present on every asset type you plan to relate.

##### relationMarker.relationKeywordRootId

> type: NodeId, required: no, default: -

The root node of relations in the keyword structure. If not configured, the plugin will read the rootId from the nodereferencefield

> > > > > The keywords for the relations will be generated automatically (if not already present when searching by name)

##### relationMarker.counterFieldId.{relationTypeId}

> type: long, required: no, default: -, since: 1.6

In case you also need to count the number of relations that an asset has, configure a map of relationTypeId → numberFieldId, e.g.

```ini
relationMarker.counterFieldId.languageVariant=123
relationMarker.counterFieldId.modelContract=124
```

See `asset-relations.xml` for the keys (e.g. `<property name="id" value="languageVariant" />`). You may skip relation types that you are not interested in counting.
