[ticker-dev] Ticker group "invitation" attachments

[Phillips, Matthew]

Hi all,

I've decided I'd like to add the ability to "invite" others to a ticker group for the next Sticker (it's about the only useful suggestion I had from JWID and I want to show willing ;) So I'm proposing a simple attachment format for ticker groups, and suggesting "application/x-elvin-tickergroup" as the MIME type. Some examples probably will get the idea across:

---

  Ticker-Group: 1.0
  Name: ticker-dev
  Type: chat

----

  Ticker-Group: 1.0
  Name: CNN
  Type: news

----

  Ticker-Group: 1.0
  Name: Interesting
  Type: custom
  Subscription: contains (Message, "foobar")

----

You'll note the idea is to use the same "name: value" format as for keys. To spec the format a little more precisely, I'm also proposing:

 * UTF-8 encoding be the default
 * To allow either \n or \r\n as the line-delimeter
 * To allow empty lines and comment lines preceded by '#'.

Also '\' would be an escape anywhere in a line, and at the end of a line would allow line concatenation eg:

  Field\:with a colon: This is a \
  multiline value for "Field:with a colon"

Comments, suggestions?

Matthew.
