A few keyword corrections for IMDb staff to make

Dear IMDb staff: can you please make the following keyword corrections?

1. films-about-indians (34 titles)

The keyword is improperly formatted. With that said, 100% of the titles that currently have this keyword have Native American characters, so the keyword should first be merged before it is blocked.

a. The keyword films-about-indians should first be merged into native-american.

b. After the merger, the keyword films-about-indians should be blocked from future use.

2. imax-version (23 titles)

This keyword is improper because it lists alternate versions of a title. That sort of info should not be in keywords. Much like the blocked keyword "not-on-dvd," this one should be blocked as well.

a. All instances of the keyword imax-version should be deleted.

b. The keyword imax-version should then be blocked from future use.

3. drew-cordeiro (41 titles)

This keyword has been used for titles directed by a person named Drew Cordeiro. That sort of info does not belong in keywords.

a. All instances of the keyword drew-cordeiro should be deleted.

b. The keyword drew-cordeiro should then be blocked from future use.

4. "time-span" keywords

The "time-span" keywords should be spelled "timespan" instead of "time-span." Accordingly, the following mergers and auto-conversions should be made.

a. Merge and auto-convert these keywords in the direction of the arrows:

one-day  --> one-day-time-span --> one-day-timespan 

Please note that this will require redirecting "one-day," which correctly auto-converts to "one-day-time-span," and changing that to instead convert to "one-day-timespan." More info here.

b. Merge and auto-convert these keywords in the direction of the arrows:

one-night (325 titles) -->  one-night-timeframe (1 title) -->  one-night-time-span (52 titles)  -->  one-night-timespan (2 titles)
