If you want to register multiple files and provide metadata for each object (data file) or collection in that upload, prepare that metadata in a Microsoft Excel XLSX file. 

1. Download the example metadata file from the following GitHub location:
   
   https://github.com/CBIIT/HPC_DME_APIs/blob/master/doc/training/samples/Example_Metadata.xlsx
   
   
2. Revise the file to reflect the objects or collections you intend to specify for upload via Globus:
   • The first column should reflect the location of each object or collection within your Globus endpoint. 
   • The second column should reflect the collection type. The default collection type is Folder. 
   • The remaining columns should reflect the user-defined attributes for each object or collection. 
   • Each row should reflect one of your objects or collections. 
   • Each object can be any file type. 
   • The system requires a row for each object or collection with mandatory metadata. 
   • If the default values are acceptable for all mandatory metadata of an object or collection, you can omit that row. 
     
     
3. Remove all formatting (such as word wrapping). 

For instructions on performing the bulk upload with the resulting XLSX metadata file, refer to Uploading Data in Bulk via the GUI.
