Plan for Qiita's system wide clean up AKA "Automatic Spring Cleaning"

[antgonza]

Last April (6 months ago) we had an internal discussion of the best way to keep Qiita free of bad datasets or data, we called the "Happy 1st: You Haven't Used The Item In Over A Year!!". This discussion yielded the below pointers for clean up and over the last 6 months the raise of new studies and users show the need to do this.

Main clean up tasks

• Close Reference extra files: do not produce and remove all from Qiita.
• Tutorial Analyses/Studies: automatic delete when they are 6+ months old.

Extra clean up points: this would need to add automatic reminders via emails to users before implementation.

• Empty Studies: delete if empty (no preps and sample information) after 6 months, no reminders
• Empty Studies: delete if no preps but sample information, send reminder at 3-5 months and delete at 6 months
• Empty Prep Info File (no raw data linked): delete after 6 months, no reminders.
• Preps with artifacts but no processing and not private or public: send reminder at 6-12-18 months, delete after 19 months.
• Analysis and analysis artifacts: reminder at 6-12-13 months, delete at 14 months if not private/public.
