Content held by the CEDA Archive is intended for long-term preservation, though for some datasets this may not be indefinite. The length of data retention is set via the Data Management Plan for the particular data in question, informed by the various CEDA data policy documents. However, in some cases items may be withdrawn. Reasons for withdrawal might include:
- Proven copyright violation or plagiarism
- Falsified research
- Legal requirements
- National security
- Planned deaccession for data that are no longer-needed
- Accidental loss of the data asset (e.g. system failure or human error)
In such cases a withdrawn item will retain its DOI and the landing page (metadata) will still be publicly available online along with a withdrawal notice stating the date and reason for withdrawal.
