Hej Ping,

Greetings from the cold north :)

No major showstoppers here - I just drafted a stylesheet S3XML<->TC (in
Sahana-Eden trunk), and also modified value representations to match the
TableCast spec, which all seems to work well.

A minor issue: I would like to be able to detect the desired data mapping
(=the type of provider/consumer) from the feed in order to perform a proper
mapping of data (~in order to make things more generic).

The "min-updated" parameter is called "msince", while "skip-record"+"limit"
are "start"+"limit" in Sahana-Eden - so we would have to rename these for a
TableCast implementation (no major problem either, I just
like "msince", "start" and "limit" better ;) ). Beyond that we support some
more query methods, see:

http://eden.sahanafoundation.org/wiki/S3XRC/RESTfulAPI/URLFormat

Best regards,
Dominic

Glad to hear it!

I'm not sure I understand, but it sounds like you are interested in the description of the columns and types?  Or is it something else?  I agree that schema discovery would be useful, and is worth thinking about, though I'd like to do that as a next step after this part of Tablecast is stable.

Good, yes, I remembered that Sahana has a much more powerful query syntax available.  I was hoping that Tablecast would not interfere with it.

Thanks,
