Hi, It's not only "can never checkout" it's also..."can never COPY into this collection", "can never MOVE out of or into this collection". The Baseline Collection itself is not VERSION-CONTROLLED and as such does not need to be checkedout to be modified. I agree it is something for an extension. I may propose an extension to the baseline feature to make the behaviour of working baselines, the protection of the baseline collection, and the behaviour of deleteing various resources (eg how to un-baseline-control) etc. I agree with all your answers to my recent questions about the baseline feature. I just feel we need to capture them somewhere more "concrete" than simply in a e-mail thread otherwise different vendors may miss some of these "subtle" points. P.S. I also like the VCCl and VCCn abbreviations and will use those in future.

The fact that it is read-only is reflected in both the fact that it is checked-in, and for a server that supports the ACL spec, the fact that it is marked read-only. The only thing you can't tell is "and all attempts to check it out will fail". I don't think that "can never check out" is an important enough piece of information to warrant a special icon/property. As for the server, it will know whether or not a resource is a member of a baseline-collection (after all, it would have to generate the property value if we defined one), so it doesn't need a property to remind it what it already knows (:-). But this certainly is a candidate for a DeltaV extension, in which case, adding it to the "extension" section of the FAQ would be the way to go.

It seems odd that the only way to identify a resource as a member of a baseline-collection is by looking at it's URL (eg where it lives in the namespace). Other preconditions can be enforced by looking at the type of resource (eg by looking either at DAV:resource-type or by looking at it's properties as in section 22), but these preconditions can only be checked by looking at the namespace. It would be nice if all members of a baseline-collection had some property to identify them as such, so that the implementation of the code to enforce the preconditions can be simple and so that clients can also identify these resources (perhaps show them greyed-out to indicate they cannot be modified).
