I realize that many in this group are focused exclusively on Internet issues. My focus is on back-end issues especially where it deals with legacy systems exposing their functionality via WebDAV. I agree with what you pointed out when it pertains to Internet documents, however, the argument does not hold water when exposing a non-web based document repository where data structures other than file systems are used to organize documents and provide access. If we are only concerned with Internet resource documents then we can dump a whole truck load of concerns, we can also expect that WebDAV will not be the mechanism to expose the multitudes of documents held in back-end document repositories. -src >>> Larry Masinter <masinter@parc.xerox.com> 02/25/97 06:23AM >>> Steve Carter wrote: > > No, I don't feel that expediency is the issue.

In Webdav, we've been pursuing using links and site maps to do clustering, and it seems that so far we can handle these issues by having separate resources with a relationship between them, and having the lock operation work on the separate URLs. It might be that in one implementation "http://server.dom/resource/bytes=1-12" is a byte range of "http://server.dom/resource", but we don't need to standardize on that, only the relationship between them. Clearly we have to address the container/contained relationships, that locking a chapter has some effect on the lock state of the entire book. If we can handle the relationship at the larger granularity, we probably should use the same mechanism for dealing with locks even with a finer grain. Larry ! !
