[Rets-dev] RETS 2.0 Discussions

[Sergio Del Rio]

Stuart, you asked if we had any documentation about the RETS 2.0 direction
statements from previous meetings and it turns out we do, I stand corrected:

5. RETS 2.0 Discussions

The purpose of the RETS 2.0 discussion was to give some direction to the

document editors on drafting a RETS 2.0 standard. The discussion began

with a demonstration of a web-services implementation of RETS presented

by Steve Verba of Avantia. He stated that the code for the demonstration

project will be made available in open-source form. [The code will be

posted on the developer page on the RETS site.

 

Steve noted that the code included a web-services front-end to a

standard RETS 1.0 server, and that this would be a way to create a

web-services version of RETS very quickly.

 

The first issue discussed was whether to switch to SOAP as the transport

layer. This was generally agreed, although Stuart Schuessler stated that

he believed that the change should be made earlier.

 

DTD extension -- serious DTD extension -- should be another goal for

RETS 2.0. Switch to XML Schema was mooted but rejected for the time

being, since we don't have a firm enough grasp on the data dictionary to

put together a meaningful schema. Switching to schema should remain a

goal.

 

Several members noted thast the current edit rule scheme for upload

isn't sufficient for final validation, and suggested that a more

sophisticated rule scheme be included in RETS 2.0.

 

Expansion of functionality is also a major goal. The objective should be

to permit RETS servers to interoperate easily with other web-services

based standards. There should also be additional functionality for

ordinary agent functions. The extent to which this requires transaction

changes is unclear.

 

Finally, as indicated suggested above, RETS 2.0 should offer a full

web-services model. Implementation of this should be optional, not

required.

Sergio Del Rio
