Comment noted. PORTUGAL Concerning Part 11 - Products Specifications, section 11-7.4 "Object Identifiers", in this section it is strongly recommended the specification of "persistent global identifier" for features and information and objects, however it is also mentioned that some objects/conditions do not need identifiers. In our opinion, the data product specification shall define exactly what those objects/conditions are. Furthermore, the data product specification shall define objectively the rules to construct the "namespaces" in order to avoid ambiguities. The S-100 WG Chair thanks Portugal for its comment. The S-100WG Chair encourages Portugal to submit this proposal using the official proposal mechanism for changes to S-100 for consideration by the Working Group.
