This document specifies these requirements. It also supports a variety of other goals related to the achievement of semantic interoperability, for example, as concerns legacy ontologies developed using heterogeneous upper-level categories, where a coherently designed TLO can provide a target for coordinated re-engineering.<\/p>\n<p>This document specifies the characteristics an ontology needs to possess to support the goals of exchange, retrieval, discovery, integration and analysis of data by computer systems.<\/p>\n<p>The following are within the scope of this document<\/p>\n<ul>\n<li>\n<p>Specification of the requirements an ontology needs to satisfy if it is to serve as a top-level hub ontology.<\/p>\n<\/li>\n<li>\n<p>Specification of the relations between a top-level ontology and domain ontologies.<\/p>\n<\/li>\n<li>\n<p>Specification of the role played by the terms in a top-level ontology in the formulation of definitions and axioms in ontologies at lower levels.<\/p>\n<\/li>\n<\/ul>\n<p>The following are outside the scope of this document:<\/p>\n<ul>\n<li>\n<p>Specification of ontology languages, including the languages OWL 2 and CL, used in ontology development with standard model-theoretic semantics.<\/p>\n<\/li>\n<li>\n<p>Specification of methods for reasoning with ontologies.<\/p>\n<\/li>\n<li>\n<p>Specification of translators between notations of ontologies developed in different ontology languages.<\/p>\n<\/li>\n<li>\n<p>Specification of rules governing the use of IRIs as permanent identifiers for ontology terms.<\/p>\n<\/li>\n<li>\n<p>Specification of the principles of ontology maintenance and versioning.<\/p>\n<\/li>\n<li>\n<p>Specification of how ontologies can be used in the tagging or annotation of data.<\/p>\n<\/li>\n<\/ul>\n<h4>PDF Catalog<\/h4>\n<table border=\"1px\" class=\"des-table\">\n<tr>\n<th>PDF Pages<\/th>\n<th>PDF Title<\/th>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>undefined  <\/td>\n<\/tr>\n<tr>\n<td><b>6<b><\/td>\n<td>Foreword  <\/td>\n<\/tr>\n<tr>\n<td><b>7<b><\/td>\n<td>Introduction  <\/td>\n<\/tr>\n<tr>\n<td><b>9<b><\/td>\n<td>1 Scope <br \/> 2 Normative references  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>3 Terms and definitions  <\/td>\n<\/tr>\n<tr>\n<td><b>13<b><\/td>\n<td>4 Requirements for a top-level ontology <br \/> 4.1 TLO as textual artefact <br \/> 4.1.1 Overview  <\/td>\n<\/tr>\n<tr>\n<td><b>14<b><\/td>\n<td>4.1.2 Relations between textual artefact and axiomatizations of the TLO <br \/> 4.2 Axiomatization in the Web Ontology Language (OWL 2 with direct semantics) <br \/> 4.2.1 General  <\/td>\n<\/tr>\n<tr>\n<td><b>15<b><\/td>\n<td>4.2.2 Alternative OWL 2 Axiomatization <br \/> 4.3 Axiomatization in a CL-conforming language <br \/> 4.4 Supplementary documentation <br \/> 4.4.1 Overview  <\/td>\n<\/tr>\n<tr>\n<td><b>16<b><\/td>\n<td>4.4.2 Documentation of the purpose of the TLO <br \/> 4.4.3 Documentation concerning demonstration of conformance of a domain ontology to the TLO <br \/> 4.4.4 Documentation concerning consistency of the CL axiomatization <br \/> 4.4.5 Documentation concerning the relation between OWL and CL axiomatizations  <\/td>\n<\/tr>\n<tr>\n<td><b>17<b><\/td>\n<td>4.4.6 Documentation demonstrating breadth of coverage  <\/td>\n<\/tr>\n<tr>\n<td><b>21<b><\/td>\n<td>4.4.7 Domain neutrality <br \/> 4.4.8 Ontology management <br \/> 5 Conformity <br \/> 5.1 Overview  <\/td>\n<\/tr>\n<tr>\n<td><b>22<b><\/td>\n<td>5.2 Ontology documentation <br \/> 5.3 Supplementary documentation  <\/td>\n<\/tr>\n<tr>\n<td><b>23<b><\/td>\n<td>Annex A (informative)  Examples of ontology suites  <\/td>\n<\/tr>\n<tr>\n<td><b>24<b><\/td>\n<td>Annex B (informative)  The definition of \u2018ontology\u2019  <\/td>\n<\/tr>\n<tr>\n<td><b>27<b><\/td>\n<td>Annex C (informative)  Examples of documentation demonstrating breadth of coverage  <\/td>\n<\/tr>\n<tr>\n<td><b>29<b><\/td>\n<td>Annex D (informative)  Conformance of a domain ontology to a TLO  <\/td>\n<\/tr>\n<tr>\n<td><b>31<b><\/td>\n<td>Bibliography  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Information technology.
