- Prepare wiki pages containing details and summaries of data which is proposed for deletion: 15-Nov-2024
- Deletion announcement sent to MWA members via email and four week consultation period start: ??-Nov-2024
- Four week consultation period end: ?? December 2024 at 23:59 AWST

the dataset in question;
the reason(s) for temporary retention of the dataset- for example,
the the significance of the dataset, the data retention requirements of the researcher’s institute, and
the proposed the proposed plan for copying and storing the dataset offsite.
total size of the dataset to be retained
The MWA Director (or delegate) will then assess the request for retention and will respond in writing. Please note that any of the data approved for retention will not be deleted this round.
