Coresource Questions: How to Recover a Deleted Asset (Duplicate file error)

When an asset (front cover image, epub, web PDF, mobi, etc) has been deleted from Coresource, it disappears from sight, but a history of the asset remains in the deep caverns of Coresource’s memory. Or as we like to say, the ghost of your asset still exists. In order to reinstate this asset, you will need to upload a new asset, but not before following a few steps to ensure it uploads without the error Duplicate file. 

  1. Before attempting to upload any asset files, start up a fresh new Excel metadata template. You can download this from Coresource under the Help menu > Downloads > Metadata Template (Non Audio).
  2. In the metadata spreadsheet, fill in the first three required columns: Title Group ID, ISBN13, and Asset Type. The Asset Type corresponds to the asset you are attempting to reupload: an epub, front cover, etc.
  3. Under Asset Status and Publishing Status, mark both as Active.
  4. Save this metadata template with your publisher name and the date in the following format: Publisher_YYYYMMDD (example: ACP-eboundbooks_20220125)
  5. Upload this file to Coresource.
  6. After the metadata has been successfully ingested to Coresource, go ahead and upload the asset files again.
  7. After the files have been successfully ingested to Coresource, ensure that they are marked as Active there. If they aren’t, click the grey Edit button along the top and mark them as Active.
