Using Declad

Using Declad

Once Declad has been configured to monitor a dropbox, to use Declad, all you need to do is place files, along with matching metadata files (but see Metadata Extractors), in the dropbox directory. It will periodically scan the dropbox directory, transfer files to their configured destination, and declare them to the configured data management systems.

Declad also has a monitoring web interface, which if you have enabled it in your configuration, lets you check on the status of the service, browse the dropbox, and view the history of transferred files, etc.

• named filename.json for a given filename
• valid JSON format
• in eiter SAM's metadata format, or Metacat's
• currently requires at least the following fields by default (list is now configurable):
  • file_size
  • checksum
  • runs
