This ontology includes many code list vocabs which you can access via a link on the ontology HTML page (top right) or directly at http://gnafld.net/def/gnaf/code/. The ontology is quite stand-alone: defined from the G-NAF data model and for the G-NAF LD version so should be un-controversial.

The code lists here are used beyond the G-NAF so a reviewer might reasonably ask for more information about the authority of the code lists and whether or not this single URI for them bundled with the ontology is sensible.

A reviewer might also question CSIRO’s authority as the submitter here (on behalf of PSMA) and ask for other agencies to weigh in regarding the code lists. What might be sensible is that some of the code lists (the four AS4590 ones) are presented separately. This will be fine for both the ontology and the dataset's use of those vocabs and their contents.

This ontology defines the data model of the G-NAF dataset that is under the authority of PSMA. Therefore the proposed URI http://linked.data.gov.au/def/gnaf is appropriate for the ontology. Approved.

The ontology is well designed and I have made some errata comment on an earlier versions that have been incorporated. There are some minor errors in the ontology/figures that need to be fixed, but that does not preclude the assignment of the URI http://linked.data.gov.au/def/gnaf .

- the base URI needs to be http://gnafld.net/def/gnaf#
- the minimum cardinality of has Alias is 2 in figure 1 and figure 2, but that is not supported by the axioms in the ontology

There are some hoops to jump through to determine the URI for the AS4590 codes. At this stage, we’d like to experiment with the governance of the code lists in consultation with ICSM’s Permanent Committee on Addressing. If, after developing expertise and experience with the proposed governance arrangements, hosting the codes as identifiers under the same URI becomes controversial, we can publish the codes under an agreed upon URI and mark them as the same (or use another mechanism to mark them as deprecated in favour of the authoritative URIs). This should not stop us from getting up and running, as the Control Body will need something to help them cut their teeth on.

A reviewer might also question CSIRO’s authority as the submitter here (on behalf of PSMA)

They might reasonably ask this. It would be great if the catalogue supported members (like CSIRO) requesting URIs on behalf of non-member organisations (like PSMA) owing to the nature of special circumstances like G-NAF where a dataset is recognised as foundational by government but is not created or owned by it. Essentially this is a delegation from Register Manager to Registry Manager.

... and ask for other agencies to weigh in regarding the code lists. What might be sensible is that some of the code lists (the four AS4590 ones) are presented separately. This will be fine for both the ontology and the dataset's use of those vocabs and their contents. 

The organisations that comprise ICSM’s Permanent Committee on Addressing are the authors of AS/NZS 4819 who originally created the code lists that were later adopted for AS4590. The acceptance of these organisations’ representatives as the Control Body for the maintenance of the codes shouldn't be controversial.
