1. What's the relevance of referring to a random blogpost about data wallets, as opposed to e.g., https://en.wikipedia.org/wiki/Digital_wallet as worst case or something more "authoritative" or internationally acknowledged or backed by a standards development body?
2. If and how is a dataverse OS's data wallet may be compatible with a Solid "pod"? Can you link to relevant specifications?
3. Can you link to any Solid specification that's making the case for solid:Wallet?
4. Can you link to any (open source) Solid server or application that's currently using or making a public call for needing this (or similar class)? How do they function without this class?

This is all so that we don't randomly add / pollute stuff in Solid Terms. We have done that in the past because there was no process. See also https://github.com/w3c-cg/solid/blob/main/CONTRIBUTING.md#vocabulary-management

This a PR discussion not a spec. Thought the blogpost would help people know that wallets are a thing.
Are you suggesting we should add https://en.wikipedia.org/wiki/Digital_wallet to the ontology?

If and how is a dataverse OS's data wallet may be compatible with a Solid "pod"? Can you link to relevant specifications?

The intent is that a Wallet in Solid will be a container which specifically stores things like credentials. It could be all or (typically) part of a pod.

There is an existing community which is not currently solid compatible at the The OpenWallet Foundation but there is a lot of potential synergy

Can you link to any Solid specification that's making the case for solid:Wallet?

No, this is a placeholder. We could mark it as such.

Can you link to any (open source) Solid server or application that's currently using or making a public call for needing this (or similar class)? How do they function without this class?

1. I was thinking of writing a pane for SolidOS which would do simple wallet management.
2. . If I was to add this to SolidOS think I'd want to use the class so one could track a wallet using type Indexes.
3. The inrupt open source data wallet application puts your wallet related stuff in your pod. It uses a custom API in the backend but the data ends up in a wallet container within your pod.

Suggested change

	rdfs:comment "A part or all of a pod which contains credentials, etc." ;
	rdfs:comment "A part, up to all, of a pod which contains credentials and related documents." ;

It's great to hear the inrupt data wallet does end up with data in the pod.

If I understand correctly, this is a class that would be referred to in a type registration as something like

solid:forClass solid:Wallet;
solid:instance </path/to/wallet/>

solid:Wallet is then a Data Library for credentials with its own domain specific index. I like the idea of formalising this to help clarify how wallets and Solid relate, but I don't yet understand what shape the data would end up being or what level of compatibility a solid:Wallet will have with competing standardisation efforts? Inrupt's documentation seems to refer to binary payloads? Is a solid:Wallet just a class of container? Or does it have more structure?

Similar to my comment on #94 (comment)

One of the CG work items listed on https://solidproject.org/TR should use a predicate first. Based on that, it could be added to the vocabulary. I also proposed both PRs as a topic for the next CG meeting.

More generally, isn't a Solid POD already a "Data Wallet"? I thought the term Wallet was just being used as a marketing term to help people understand the purpose of the technology, but in technical terms I don't see what a "Data Wallet" has that a "Solid POD" doesn't.

Looking at the PR, if a data wallet is "A part or all of a pod which contains credentials, etc.", shouldn't it be possible with the current spec to register something in the type index as a container for credentials? Why do we need a new term to express that a container includes some type of data?
