RE: [alf-dev] ALF SCM Vocabulary compared to WebDAV VersioningExtensions

One issue is that WebDAV is not a SOAP based web service and is not (probably cannot be) described by WSDL.  Thus it isn't directly usable from BPEL. (should double check to be sure I'm not missing something)
 
I have a general impression that the versioning part of WebDAV has had mixed acceptence and spotty implementation but I'll leave it to others to expand on that.
 
Both WebDAV and JSR are client oriented and have the same "workspace" issue that we need to address to avoid streaming files through the BPEL engine.
 
Thus I believe neither is directly applicable although clearly they are both good sources to leverage and validate against.  It would be a good exercise to reference the equivalent concepts and operarations of these two sources in our document.

Subject: [alf-dev] ALF SCM Vocabulary compared to WebDAV VersioningExtensions

The document Versioning Extensions to WebDAV (Web Distributed Authoring and Versioning) I found here http://www.ietf.org/rfc/rfc3253.txt
has a section of Term definitions which is very close to what has been proposed which seems very good.  It also looks like WebDAV has already been implemented by some SCM products. I don’t know how complete these implementations are but again, this seems like good news.
 
But I have a couple of other questions related to this:
1.    Why doesn’t JSR 147 doesn’t reference the document above it seems like they address identical areas. 
2.    Is it possible for an ALF managed BPEL script to be written using existing WebDAV support already in SCM products?
3.    If 2 above is true then should we base our vocabulary as directly as possible on the existing WebDAV standard?
 
I know nothing about WebDAV and only know about SCM systems from a user perspective so these are probably naïve questions.  However, I am curious.

 

Thanks for any information
