As the Sync Tool transfers files to DuraCloud, it will attempt to capture certain types of metadata about each file, and include that information as part of the content item added to DuraCloud. The list below describes the metadata that is captured automatically. You have the option to add, update, or delete the properties of each file that after it has been transferred to DuraCloud.
- Mime Type
- The content type of the file.
As the Sync Tool transfers your files to DuraCloud, it attempts to determine the mime type of each file based on the file's extension. If it cannot determine a mime type for a given file, that file's type is set to "application/octet-stream", which is a generic mime type for binary data. Select the "Edit" button on the DuraCloud web interface to change a file's mime type.
If you find that files with certain extensions are not being mapped as you would prefer, you can always change the value on uploaded files from within DuraCloud. If you would like to make sure that files with a given extension are given your preferred mime type during upload, you simply need to update the mapping file. The mapping of file extension to mime type is determined by a file included in your Java installation called content-types.properties. This file is usually located in the "lib" folder under your Java runtime installation directory. After making a copy of the original file as a backup, simply update it following the formatting conventions used throughout the file to include the mappings you prefer, then save the file. After making changes, you will need to re-start the Sync Tool to ensure that the changes are picked up properly.
