It seems like it would be really useful to cover OpenRefine's Extract/Apply functionality in this lesson. This functionality is visible in the Undo/Redo area. Extract creates a precise representation of all changes made in JSON, which can be copied and saved; Apply allows users to paste that in, and perform all the operations on a new data set.

I can see this being useful for both social science and natural science data, in particular. Is this something that would be useful for me to write up and add? I don't think it would take a particularly long time to include; possibly within 10 minutes or less.

This sounds like it might be a useful addition. I'd be worried about making this portion of the lesson too long. @ErinBecker or @fmichonneau, do you happen to know how the timing for this lesson has worked out for people who have taught it (or where I could find this information)?

[fmichonneau]

I haven't OpenRefine lesson in a very long time. @debpaul do you think there is room to add this? (it's for the social sciences, but it's almost the same lesson as for the ecology curriculum).

[debpaul]

Yes @paigecm that would be a great addition. I do think many of us mention / show / include this when we are teaching this lesson - depending on time allotted. It just has not been added formally.

Thanks @debpaul. I think, then, it sounds like something to work on if it can be kept to about 10 minutes. @paigecm, are you still interested in tackling this?

[paigecm]

Yes! Sorry; I was away from the office so couldn't tackle this, but I'd be happy to, and it's easily something that could be tackled in 10 minutes.

Episode 5 of the lesson seems to cover OpenRefine's Extract and Apply functionality as suggested by the people here. Thanks again for the suggestion and discussion! I will therefore close this issue, but please feel free to reach out if I missed anything and it shouldn't be closed yet.

(Note that #95 mentions that the episode has time allocated for exercises, but there don't seem to be any exercises. That is still being discussed.)
