Hi, I like to draw your attention to two artefacts: In https://forge.ogf.org/sf/go/artf6570 and https://forge.ogf.org/sf/go/artf6575. * artf6570 proposes to pick the following URI for NML base schema: For the base schema: http://schemas.ogf.org/nml/2012/10/base# For subordinate schemas: http://schemas.ogf.org/nml/2012/10/ethernet# After publication, we will publish a HTML document at this schema pointing to (a) the GFD standard, (b) the XML schema and (c) the RDF schema. Pointers are -if possible- augmented with computer readable (e.g. RDDL ) pointers. Furthermore, I propose to stick with "2012/10" as the date, so implementations can start using that. Schemas that are published before the NML-base document is ratified MUST contain a large warning "DRAFT SCHEMA", but can use these URIs. * artf6575 proposes to use "http://schemas.ogf.org/nml/2012/10/base#" for Relations (instead of a seperate namespace). It explains how RDF should distinguish between NML relations and non-NML relations using the following triplet: nml:hasInboundPort a nml:Relation . If there are any issues with these two proposals, please reply on-list. Otherwise, I like to move these forward quickly. Freek
