It is clear to me how to refer to a list item (restconf draft) but it is not clear how to refer to a specific leaf-list entry.
For example, given the following definition:
module x {
container y {
leaf-list z;
}
}
and if I have the following data in the system
<y>
<z>a</z>
<z>b</z>
<z>d</z>
</y>
how do I insert a c in the third position ?
Restconf has the 'insert' and 'point' that takes the resource uri. But, what is the resource uri to identify a leaf-list item ? If I want to refer to the second entry, is the following valid ?
/y/z=b
Each leaf-list entry is a separate data resource in restconf-draft-10.
Containers, leafs, leaf-list entries, list entries, anydata and anyxml nodes are data resources.
This is what Section 3.5 says about leaf-list entries. Further it defines encoding of leaf-list Data Resource Identifiers in 5.3.1:
If a data node in the path expression is a YANG leaf-list node, then the leaf-list value MUST be encoded according to the following rules:
o The instance-identifier for the leaf-list MUST be encoded using one path segment [RFC3986].
o The path segment is constructed by having the leaf-list name, followed by an "=" character, followed by the leaf-list value. (e.g., /restconf/data/top-leaflist=fred).
So, your example for second entry it would be: /restconf/data/x:y/z=b.
As for inserting, it seems to be unclear. There are examples in the appendix D of the draft for both point and insert, but use a list instead of a leaf-list (note that both MUST be ordered-by user in order for the two parameters to be valid in a request).
