If your If your user account has the Write or Own permission level on an existing collection in DME, and if that existing that existing collection has been configured to contain data files, the following command allows you to upload you can register a data file to into that collection. You can choose whether to upload synchronously (from your file system) or asynchronously (If the file is larger than ten GB, register it from a Globus endpoint):

The character limit for each metadata value is 2700.
To register a data file:
- Choose whether to register from your local system, a Globus endpoint, or an S3 bucket.
- To register from your local system, plan to use the source file parameter to specify the file that you want to register.
- To register from Globus, S3, or Google Cloud, plan to use a JSON file to specify the file that you want to register.
In your local system, create a JSON file that specifies the metadata for the new data file. The

For each date attribute, specify one of the following date formats, and specify the date value in that format:
- yyyyMMdd
- yyyy.MM.dd
- yyyy-MM-dd
- yyyy/MM/dd
- MM/dd/yyyy
- MM-dd-yyyy
- MM.dd.yyyy
The system parses your date using the date format you specify. Then however, if the date attribute has a metadata validation rule in a different format, the system stores the date in the format specified by that rule.

Panel borderColor silver borderStyle solid Clipboard AllowLineWrap true dm_register_dataobject [optional parameters] <description.json> <destination-path> [source-file]
The following table describes each parameter:
Parameter Description [-h] If you want to print a usage (help) message for this command, specify this option. [-D <REST-response>] An optional parameter, specifying a path and filename in your local system. The system always creates a response file:
- If you specify this parameter, the system saves the response from the server to the specified file in the specified location.
- If you omit this parameter, the system saves the file as dataObject-registration-response-header.tmp in your home directory.
[-o <output-json-file>] An optional parameter, specifying a path and filename in your local system. The system always creates an output file:
- If you specify this parameter, the system saves the output to the specified file in the specified location.
- If you omit this parameter, the system saves the output as dataObject-registration-response-message.json.tmp in your home directory.
If the command is successful, the output file is empty.
<description.json>
A path to the JSON file that specifies the metadata for the new data file. <destination-path>
A path within DME, including the name of the file you intend to register. Specify where you want the system to create the new data file. (If you specify an existing data file, this command updates the metadata for that data file. For details, refer to Updating Data File Metadata via the CLU.) [source-file]
A path to a file in your

local system:

- register.
- If you are

For instructions on performing similar tasks in the GUI, refer to the following pages:
- Registering a Data File from the Register Data File Page
- Registering a Data File from the Browse Page
For example, the following command registers the data.txt file from the JaneDoe folder in the local system to the Project_New collection in DME:
