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, you can register a data file into that collection. If the file is larger than ten GB, register it from a Globus endpoint or , an AWS S3 bucket, or Google Cloud rather than from your local system. (To update metadata, refer to to Updating Data File Metadata via the CLU.)  

...

1. 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 To register from Globus, S3, or S3Google Cloud, plan to use a JSON file to specify the file to specify the file that you want to register. 

2. In your local system, create a JSON file that specifies the metadata for the new data file. The contents of this file depend on the source of your data:

   • If you are registering from your local system, specify the metadata that you want to include. Click the following link to view the syntax:

     To extract metadata from the header of TIFF or BMP image files, include the following line:

3. 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.

   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: If you are registering from your local system, use this parameter to specify the file that you want to register. If you are registering from Globus or S3, omit this parameter.
