Author names stored incorrectly

[petercollingridge]

The value for the key 'authors' in video objects is generally a list of strings of individual names, however there are 7 cases in which there is a single string "Beth Harris,Steven Zucker", as opposed to two strings.

Rishi is sometimes referred to "Rishi" and sometimes "Rishi Desai". Karl Wendt is sometimes stored with a space after his name, sometimes not.

Thanks for letting us know about this.

@stchangg?

I don't think there is anything wrong with the code, there is just a lot of inconsistency with the data that someone will have to go back and correct. I believe Marcia's new UI will help to fix this going forward.

[sophiebits]

Would be nice if the field stored and encouraged you to use existing values.

Thanks Tom & Ben. Yes this is the case. I added the author_names field just as a quick and simple fix to add the Google+ author links, and didn't make the input fancy (the data type is simply an array of strings) since Marcia was going to overhaul the content editing tool. We can retroactively fix some of this data inconsistency through backfills later.

aloha @petercollingridge! if you'd like to send me those 7 cases, i'll update them to be consistent. the new-ish (and still being iterated upon) interface for editing videos/exercises will prevent these author name inconsistencies in the future. https://s3.amazonaws.com/uploads.hipchat.com/6574/17223/utgk2kki7s66nmv/upload.png

thanks for all that you do! marcia

What information do you need? I'm calling: /api/v1/playlists/library/list

The titles of the videos are: "Ancient Greek Temples at Paestum, Italy" "Ara Pacis" x 2 "Pair of Centaurs Fighting Cats of Prey from Hadrian's Villa" "Exekias, Attic black figure amphora with Ajax and Achilles playing a game" "Giorgione's The Adoration of the Shepherds" "Institutional Critique: Hans Haacke's Seurat's 'Les Poseuses' (small version)"

Thanks for that. I really wasn't a big problem, I just noticed they were inconsistent. The new interface looks very nice.

[petercollingridge]

Just curious - the genetics 101 videos (e.g http://www.khanacademy.org/science/biology/heredity-and-genetics/v/genetics-101-part-1--what-are-genes) have Sal as the author and yet they are not narrated by him. Should there be another author for them?

[sophiebits]

@petercollingridge That's definitely a mistake. I've removed Sal as a listed author, so currently there isn't anyone listed.
