Re: Past discussions on vCard datamodel for contacts API (ISSUE-71)

Providing an informative mapping to vCard properties is fine but using it as a basis for our data model is something I'm not convinced.  

There are several standard (e.g. vCard, XMPP, Portable Contacts, OMA CAB) and proprietry contact formats (e.g. internet-based and handset/device based). In this situation, I don't believe vCard stands out as the preferred format.

Our goal I believe should be to provide access to underlying address books whether it be on the device or a service, but not the other way around i.e. forcing implementations to support a specific model.

The common/minimum subset approach allows compatibility with almost all formats out there, and I believe this is the best approach at least for the first version.

We certainly don't help it by adding further fragmentation.  The current working draft (when looked at from a vcard perspective) does precisely that.  E.g., how is the "premises" attribute mapped into vcard?

I disagree with that scope point.  The API we're talking about should: 

- be able to deal with address books that reside on the network; for these, vcard is the standard of record  (feel free to suggest another one)
- be useful as a JSON binding that can be used as a network transport

(There's, in fact, a requirements discussion in here that's perhaps best framed in those very terms.)

One way to achieve that would be to indeed focus on the API framework, and simply define a mechanical mapping from vcard to JavaScript objects.
