Updating Collection Metadata via the CLU

If your user account has the Write or Own permission level on an existing collection in DME, you can use a CLU command to update the metadata of that collection. 

To update the metadata of a collection:

1. Consider the metadata requirements for the type of collection that you intend to update: 
   • What are the required attributes for this collection type?
   • What are the acceptable values and default values for each attribute?

2. In your file system, create a JSON file that specifies the metadata for the collection, as follows:

   {
       "metadataEntries": [
           {
            "attribute": "project",
            "value": "my-project-name"
           },
           {
            "attribute": "collection_type",
            "value": "Folder"
           }
       ]
   }

3. Run the following command:

   dm_register_collection <description.json> <destination-path>

   The following table describes each parameter:

   Parameter	Description
   <description.json>	A path within a file system, including the name of the JSON metadata description file that specifies the metadata for the collection you intend to update.
   <destination-path>	A path within DME, including the name of the collection you intend to update.

   The command registers the metadata specified in <description.json> to the <destination-path> in DME. 

For example, the following command updates the Project1 collection within the PI_Lab1 collection, based on the metadata in the my-collection.json file:

dm_register_collection my-collection.json /Example_Archive/PI_Lab1/Project1

The JSON file must contain metadata for the collection, Project1.
