Hi,

A couple of days ago Dave M.  pointed out that ErlyWeb could benefit
from
a web services framework (in the thread about Strenghts and
Weaknesses).

I would be willing to try to improve this, but I would like some
guidance: what
should it do?

I will probably use the existing yaws+erlsom implication as a basis,
but I agree that it
can be improved. In particular the set-up could be easier.

- I already have some code available that improves the handling of
import statements.

- What flavours of webservices should be supported? Currently we have
the
'document/literal' type only.

- What type of interoperability issues should I be aware of?

- Should there be a strong link to the rest of erlyweb? What should it
look like? Or would
it be sufficient to offer support for web services in YAWS in a nice
way? The handlers could
call the ErlyDB APIs, of course.

- Should there be a generic framework that also covers XMLRPC, REST,
Json? Is there an
example of such a framework - maybe in Ruby? I can imagine something
generic for all the
XML based variants, but I struggle for JSON. Not because it is not
XML, but because there
appears to be no 'schema' for JSON. It seems to me that such a
framework would require
some kind of metadata/specification, like a schema or WSDL.

- anything else?

Regards,
Willem
