You can use a CLU command to create an empty collection in DME. With the same command, you can create a parent collection for the empty collection. This command has the following prerequisites for the existing collection in which you intend to create the empty collection or the parent collection of the empty collection:

• Your user account has the Write or Own permission level on

...

• the existing collection

...

• .
• That existing collection has been configured to contain another

...

• collection. 

To create an empty collection:

1. Consider the metadata requirements for the type of collection that you intend to create: 
   • 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 new collection, as follows:

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

3. In your JSON file, if you want to create a parent collection for the empty collection, specify the metadata for the parent collection, as follows:

   Code Block
   { "metadataEntries": [ { "attribute": "project", "value": "my-project-name" }, { "attribute": "collection_type", "value": "Folder" } ], "createParentCollections": true, "parentCollectionsBulkMetadataEntries": { "defaultCollectionMetadataEntries": [{ "attribute": "collection_type", "value": "Folder" }] } }

4. Run the following command:

   Code Block
   dm_register_collection <description.json> <destination-path>

   The following table describes each parameter:

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

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

...

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

The JSON file must contain metadata for the new collection, Project_New. If the parent collection, PI_Lab1, does not already exist, then the JSON file must also contain metadata for that collection.
