If the file is larger than two GB, refer to Using dm_register_dataobject_multipart. 

The character limit for each metadata value is 2700.

To register a data file:

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

   Code Block
   { "generateUploadRequestURL" : true, "metadataEntries": [ { "attribute": "description", "value": "my-dataObject-description" }, { "attribute": "example_date", "value": "20201231", "dateFormat": "yyyyMMdd" } ] }

2. 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.

4. Run the following command:

   Panel
   borderColor silver borderStyle solid
   Clipboard AllowLineWrap true dm_register_dataobject_presigned [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 file 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 file 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.
   <source-file>	A path in your file system, specifying the data file that you want to register.
