Parse out dates, pre-/suffixes, titles, and fuller forms in personal names

[regineheberlein]

User Story -- briefly describe the problem:

Catalogers observe that there are large numbers of names with dates in $a.

Example record(s) where you observed this problem

• MMSID:
• Record (cut&paste): 600 17 Clemons, Harry, 1879-1968. ǂ0 https://viaf.org/viaf/22503840 ǂ2 viaf (PULFA)C0627 [NB this is an obsolete example; the ind2, $0 and $2 are no longer there]

What should that Record look like instead?

• Record: 600 10 Clemons, Harry, $d 1879-1968. ǂ1 https://viaf.org/viaf/22503840 ǂ1 https://viaf.org/viaf/22503840

Possible workflow:

1. get all person agents
2. filter by those having a date pattern in the title but not in the date fields
3. parse out beginning and end date
4. copy date string to date expression field
5. copy beginning and end date to date fields
6. post
