Configure Metadata

This topic describes how the metadata can be configured through DAM extensibility.

Overview

DAM Extensibility feature improves and empowers DAM to support user-defined custom renditions and configure transformations for assets. Adding to the configuration of metadata generation for all renditions, you can now configure metadata generation specifically for MIME types and their renditions.

Metadata configuration via DAM extensibility

Similar to rendition and thumbnail actions such as crop and resize, the Image processor plugin also supports metadata extraction so that DAM invokes the Image processor plugin by default. In case of custom plugin, corresponding API can be configured in the Plugins configuration as follows.

The first change is in the Plugin configuration, which specifies the methods and URL to be invoked for metadata generation.

Note

The action name needs to be metadata and cannot contain any custom names.

pluginsConfiguration:
  image-processor:
    url: http://RELEASE_NAME-image-processor:DAM_HTTP_PORT/dx/api/image-processor/v1/plugin
    callBackHost: http://RELEASE_NAME-digital-asset-management:DAM_HTTP_PORT
    authKey: Key
    enable: true
    actions:
      metadata:
        params: {}
        url: "/metadata"

The second change is to add metadata to the new stack configuration SupplementalStack in rendition configuration.

Note

The operation name needs to be metadata and cannot contain any custom names.
Example
```
image/jpeg:
rendition:
- name: Original
  transformationStack: []
  thumbnailStack:[]
  supplementalStack:
  - plugin: image-processor
    operation:
      metadata: {}
```
