Info from Invaluable

I am in contact with Invaluable, and they have kindly provided some additional info:

• Two new formatter URLs, which I have added (I've marked the old one as deprecated)
• Their IDs are, canonically, lower case, though other forms will work. I'll ask for a bot to convert the values we have to date.

They're also going to be providing some data dumps, details later. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 18:56, 20 March 2018 (UTC)

Do you think that is necessary the second URL? In addition, it has two blank spaces. --Gerwoman (talk) 19:25, 20 March 2018 (UTC)

I've fixed the spaces, thank you. Apparently, that is the form that shows up most in Google results, but I'm ambivalent about whether we show it or not. Pigsonthewing-bot (talk) 20:02, 20 March 2018 (UTC)

Interesting. I never use that website, mostly because the metadata is so bad I can't do anything with it. If it turns out to be useful then I will be pleasantly surprised. Jane023 (talk) 21:00, 20 March 2018 (UTC)
