Vote TES with Comments on NISO Z39.103-202x Standards-Specific Ontology Standard
The Standards-Specific Ontology Standard (SSOS) provides a high-level generic ontology which describes the life cycle of consensus-based standardization projects and published standardization deliverables, i.e., standards. Developers, publishers, distributors, and users of standards, including national standards bodies, regional and international standards bodies, standards development organizations, and business, can use SSOS to better structure the life cycle information of their own standards or to better structure and automatically analyze and compare development stages of standardization activities and the life cycle of standards publications.
In the Section “3.9 General Terms and Definitions” of this NISO Z39.103-202X, SSOS: Standards-Specific Ontology Standard, the definitions for ‘taxonomy’, ‘thesaurus’ and ‘ontology’ need to be updated, not just ‘controlled vocabularies”. The first two cited ANSI/NISO Z39.19-2005 R2010. The 3rd one is not officially defined and really need to be updated.
Please consult the ISO 25964-2:2013, align with the Terms and Definitions. E.g., a thesaurus should not be just ‘controlled vocabulary’, but also ‘structured vocabulary’. 
controlled (3.19) and structured vocabulary (3.74) in which concepts (3.17) are represented by terms
(3.84), organized so that relationships between concepts (3.17) are made explicit, and preferred terms
(3.62) are accompanied by lead-in entries for synonyms (3.78) or quasi-synonyms (3.64)
NOTE The purpose of a thesaurus is to guide both the indexer and the searcher to select the same preferred term or
combination of preferred terms to represent a given subject. For this reason a thesaurus is optimized for human
navigability and terminological coverage of a domain.
