Are there any best practices ? 16:18:22 #info - If some one pushes it through restconf things get interesting. 16:19:01 #info colindixon asks if ther'es a way to sanely canonicalize values that are set outside your purview, e.g., set via RESTCONF 16:19:17 #info - Robert says changes for Ipv6 utils are not done yet. 16:19:26 #info rovarga_ says not at the moment, some classes exist to help 16:19:41 #info - Robert says in case of Ipv6 it is hard to say what exactly is canonical format 16:20:23 #info - colindixon asks if there is one unit of utility classes where canonical forms are defined that would be great. 16:21:39 #info - Robert says there is no way with out interacting with datastore .. (have to convert it back ) .. so there is not much value in creating it. 16:23:18 #info - There is already a utility class which has canonical forms with ipv4 16:23:25 #undo 1 16:23:25 Removing item from minutes: 16:23:34 #info - Robert says There is already a utility class which has canonical forms with ipv4 16:25:49 #info - Robert says converting bytes result in canonical , converting from bytes it could be another adddress or byte . So it is possible to generate the end result as canonical form 16:27:44 #info Robert brings up MAC address issue in case of canonical forms and says overriding the MAC address is the only possible solution 16:28:03 #topic Bug 5396 16:28:45 #info - Regex processing of yang models is broken.
