I suppose you could limit it t= o printable ASCII characters, in order to eliminate the impact of Unicode c= onfusables.=20 Within nss-root MGMT, the nss-restoftree will have the following structure= : =20 urn:onem2m:mgmt.:nwkType::[] I suppose the dot after mgmt is an error. If so, we get URNs like:=20 urn:onem2m:mgmt:nwkType:lora or urn:onem2m:mgmt:nwkType:ansi_c_12:parameter Within nss-restoftree colon has two different roles in the mgmt sub-namespa= ce. It separates both nwkType from identifier and identifier from parameter= (if any). This might create confusion regarding the role of the parameter,= since nothing in the URN syntax says that the parameter is not part of the= identifier. And if in the future you need to sub-divide nwkType, it might = no longer be obvious for someone who does not know the syntax already where= the identifier is and whether there is a parameter.=20 Since onem2m parameters will not have a role in identification, you might b= e better off including them as URN R-components. Since your URNs will not b= e resolved, this should not be problematic in any way.=20 URN namespace registrations do not need to be RFCs. An RFC can be provided = if the identifier system has not been specified elsewhere, and it is consid= ered useful to create an RFC for this purpose (see e.g. RFC 8458; https://d= atatracker.ietf.org/doc/html/rfc8458). In your case, I do not think that RF= C is required or even justified. It will be easier both for you and IETF if= you send us just a template as specified in RFC 8141. All registrations pu= blished as such templates are listed at https://www.iana.org/assignments/ur= n-namespaces/urn-namespaces.xhtml.=20 ETSI has already made one namespace registration as a template, available a= t https://www.iana.org/assignments/urn-formal/etsi.=20 All the best,=20 Juha =20 =20 I would recommend that the registration template specify how the NSSs are t= o be compared, although looking at RFC 8141, it doesn't seem to be required= . (It used to be that specifying the comparison rule was important.) I su= spect that oneM2M intends to use case-sensitive comparison and largely assi= gn NSSs in a single case.
