Currencies as units vs resource classifications
We have had a bit of discussion on this in some issue that I can't find easily now. It doesn't affect the vocabulary directly, it only affects examples. And it also affects the mapping of VF to existing or new applications, which I tend to be involved with somewhat regularly right now.
I believe @elf-pavlik has the opinion that currencies should be resource classifications, not units. I think this is because the conversion between currencies is very different than conversions between say volume or weight units, which are fixed, while currencies fluctuate all the time. Please elaborate or correct!
We did it both ways at Sensorica, and my conclusion at that time was that it is best if currencies are units. But I haven't been very solid on that conclusion, and was thinking it wasn't critical either way for VF.
Now I'm seeing it would be good to make a considered decision so that people can easily coordinate between their apps.
I'm also thinking again that it would be good to make the currencies units, which leaves the resource classification/specification for things like "social wallet", "bank account", "virtual account", "wallet address", etc. People will need to define this somewhere.
We got one quick opinion from Cheryl Dunn, one of the core REA academics, agreeing with that, and it would be good to get some more. She said "I would say that the resource type would the account (crypto-currency wallet, bank account, etc.) and that the currencies would be units of measure. This is really the first I’ve thought about it, but that approach is consistent with how we’ve handled cash accounts in the past and various measurements such as foreign currency translation."
Another good resource might be to see how the Unit of Measure ontologies/taxonomies and key web taxonomies think of it.
