AltME: Ren - Data Exchange Format

We need only a minimal set of forms. I think Ren is at 23 so far. :-)
So minimal is relative.

Well, Ladislav's ticket is here, but fork's proposal is not there - http://curecode.org/rebol3/ticket.rsp?id=2094&cursor=4 ... posting just to make it complete ... and now you can forget it :-)

My thought on simplifying is to reduce most any-string! types to one type (implied string), and collapse both block! and paren! to list. So I would rather not have separate #[] and #() types with very different rules.
:-) I remember the ticket and chat.
I am concerned that if we don't have a clear map type in Ren, it may be seen as a weakness or gap. So we have to be able to clearly state the benefits and limitations.

You can look at http://pointillistic.com/ren/ to see what I have spec'd at this point. Open questions are path types, exact word syntax, and tag values. Comments or questions on other types are welcome.

Does anyone object to this group being [web public]?

Where is this now?  Sometimes a person does not understand what he is looking at when he first sees it.  I am in an SQL training session and just learned how to export query results into XML.  As I looked at the XML results I thought, this is ghastly; someone should make a data interchange format more like REBOL.  Then I remembered that someone has...

You can see the state of things at ren-data.org.
Still some decisions to be made, and no reference implementations up yet, though I have a mostly done R3 parser for it which should port easily to R2 and Red.

Aside from the things that have ??? next to them in the informative grammar sidebar, 'quantity was something I put in there as a reminder to myself but is just a thought right now.

Do you have a tool for quick production of those railroad diagrams, or did you have to "brute-force" them?

There's a link at the bottom of the page: http://www.bottlecaps.de/rr/ui

Sorry, I just now found that link.  I always am a bit too quick on the keyboard.

NP.
