We ask archaeology dataset depositors to send a file list with each dataset,
describing their files using Data Documentation Initiative (DDI) metadata
standards. Format conversions are registered in this filelist by the archivist.

Data accessible in another way or elsewhere
Before a dataset is made accessible to the public, an archivist needs to
go through the general workflow, which comes down to:
-Check Dublin Core, edit/modify where necessary
-Assign project codes (if required)
-Download files, check for completeness / privacy-sensitive data
-Migrate files to preferred formats
-Modify directory structure (if necessary)
-Upload preferred formats
-Check individual file metadata, edit/modify if necessary
-Add individual file metadata
-Publish files (set visibility/accessibility rights)
-Create a ‘Jumpoff’ presentation page
-Check workflow
-Publish dataset
-Relate dataset to related datasets or web pages
-End administration
Files are converted to Preferred Formats. We also see if re-structurizing
files and folders would add to the clarity and coherence of the dataset.
