Sure, one mandatory to implement format, others nice to have. Interoperability good. Agreed.
But why YANG-patch and not something built for the purpose (e.g., YANG-diff) that, in particular, provides an actual diff as opposed to a data-tree operation that only shows one of the two values?

If there are multiple formats, is there a mandatory to implement format? Does the mandatory to implement format depend on the protocol that is being used? I prefer one format or if necessary I am fine with one mandatory to implement format. An open ended collection of implementation specific formats is super flexible but defeats the purpose of a standard, namely interoperability. I agree there needs to be 1 mandatory-to-implement format. IMO this needs to be YANG Patch because it is more precise then constructing an XML tree with operation attributes in it (e.g., how else do you represent a delete or a move?) Also, YANG Push is using YANG Patch format and common code for push and diff would be possible. I think other formats should be allowed. This is very tool-specific. I could see how somebody might want a textual patch of the XML representation to produce the new XML representation. /js Andy On Thu, Oct 04, 2018 at 05:41:22PM +0000, Kent Watsen wrote: > We agree that the diff-format should be client-selectable, modulo what the > server supports. yang-patch and edit-config both are viable.
