OLEditionData add fields to the definition

[bradyguyc]

There are a couple of fields that ideally would be part of OLEditionData. I suspect I can get to this via extensiondata but would be nice to have them as first party members so to speak.

Thanks

languages
source_records
last_modified

What I an trying to do is surface the best editions in sorted order based on users language and the most recently updated editions.
-- might be nice to have --
revision
created
latest_revision

This is the json that is returned with a works/../editions.json call

How commonly are these fields included in the edition API's json?

[bradyguyc]

@Luca3317 the last_modified is on every record. Language from some looking at a work that has 60 some editions it's on about 40 of those records. It appears to be missing mostly on english records tho there are some records with english listed as the language. Source I have not really looked at. It appears to be a required field for creating a work/edition but it's definition and understanding of doesn't seem to be well know.

[Luca3317]

Gotcha, last_modified and languages definitely seem like good choices to include then. source_records im not so sure about, will take a look at them soon.

About last_modified, it seems to consistently return "/type/datetime" as type. Have you had any cases where that wasnt the case? If not Ill just make a field for last_modified->value in OLEditionData.

[bradyguyc]

I have really just started looking at last_modified but know how things work at openlibrary.org I suspect it's on every record and I can't imagine a case where it's not /type/datetime. I can ask them.
