Updating Data File 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 a data file in that collection. 

To update the metadata of a data file:

1.  In your file system, create a JSON file that specifies the metadata for the data file:

   { 
       "metadataEntries": [
         {
           "attribute": "description",
           "value": "my-dataObject-description"
         },
         {
           "attribute": "my-second-attribute-name",
           "value": "my-second-attribute-value"
         }
       ]
   }

2. Run the following command:

   dm_register_dataobject <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 data file.
   <destination-path>	A path within DME, including the name of the file you intend to update.

For example, the following command updates the metadata of the data.txt file in the Project1 collection in DME:

dm_register_dataobject /cygdrive/c/Users/JaneDoe/my-metadata.json /Example_Archive/PI_Lab1/Project1/data.txt

The JSON file must contain metadata for the data file, data.txt.
