Hi all, It really was a pleasure to meet you guys last week at MWC, I hope you had a nice trip back. Working towards a common NFC draft, I'd like to setup a list of items that every side wants, so that they would be included in the spec. Feel free to add stuff as appropriate. For reference, the existing APIs are here: http://w3c.github.com/nfc/proposals/intel/nfc.html http://w3c.github.com/nfc/proposals/webinos/nfc.html What I'd like to take from the Tizen API: - A NDEFMessage interface that's an array of NDEFRecords, and the inheritance hierarchy of NDEFRecord types - Separate NFCTag and NFCPeer interfaces, each having their own methods for reading / writing or sending / receiving NDEF Messages. That allows registering a listener for NDEF messages on a peer device, that could send a bulk of messages, but just invoking a "read" method on a tag. Also, all the pairing / handover stuff is done at the NFCPeer interface level. BTW last week's slides, including the updated spec with BT handover, are accessible there: https://github.com/01org/cloud-neard/wiki What I'd like to take from the Webinos API: - It's event-based. Right now the Tizen-based API uses only callbacks, and that would not work well with the Webinos / node.js framework. If I understood correctly what Hans explained the node.js implementation uses HTML5 server-sent events. The Javascript code runs on the device, raise a very light http server, and the UI code in the web browser registers for server events. Please correct me if I'm wrong. Anyway I believe it would make sense to align with the EventTarget / EventHandler model of the Sysapps group proposals like Telephony, Messaging and so on http://www.w3.org/2012/sysapps/ As far as I'm concerned that's what I consider is important to get right, I have no strong opinion on what to do with MIME / binary data, lower level comms (LLCP), read only tags... please add your opinions and what you feel strongly about.
