And some circles with particularlyl narrow senses of it, may define it relative to a particular language or tool (imho, a mistake). </div><div dir="ltr"><br></div><div dir="ltr">Another consideration is not formally asserting it as a distinct type of model/system, but rather as an activity or process the products/output of which we may then call 'conceptual model' or some other term. I can describe what that can look like as well, if desired. </div><div dir="ltr"><br></div><div dir="ltr">D) Bottom-line: if distinctions are made, then we should be precise and clearly show what they are, avoiding making them trivial or for the sake of using a perceived trending word or topic. </div><div dir="ltr"><br></div><div dir="ltr">Robert Rovetto</div><div dir="ltr">--</div><div dir="ltr"><br></div><div dir="ltr"><br></div><div dir="ltr"><br></div></div><div id="ydpf172cf6yiv9472090321ydp5dfc9e8yiv3700751578ydp6ebc143eyahoo_quoted_9970903493" class="ydpf172cf6yiv9472090321ydp5dfc9e8yiv3700751578ydp6ebc143eyahoo_quoted"><div style="font-family:'Helvetica Neue', Helvetica, Arial, sans-serif;font-size:13px;color:#26282a;"><div><div id="ydpf172cf6yiv9472090321ydp5dfc9e8yiv3700751578ydp6ebc143eyiv7984858979"><div dir="ltr"><div class="ydpf172cf6yiv9472090321ydp5dfc9e8yiv3700751578ydp6ebc143eyiv7984858979gmail_quote"><div dir="ltr" class="ydpf172cf6yiv9472090321ydp5dfc9e8yiv3700751578ydp6ebc143eyiv7984858979gmail_attr">---------- Forwarded message ---------<br>From: <strong class="ydpf172cf6yiv9472090321ydp5dfc9e8yiv3700751578ydp6ebc143eyiv7984858979gmail_sendername">Shames, Peter M (US 312B)</strong> <span><<a href="mailto:peter.m.shames@jpl.nasa.gov" rel="nofollow" target="_blank">peter.m.shames@jpl.nasa.gov</a>></span><br>Date: Sun, Nov 12, 2023 at 11:12 AM<br>Subject: Ask the question "define ontology in computer science", and ...<br>To: Frederick Slane <<a href="mailto:freds@spacestandards.org" rel="nofollow" target="_blank">freds@spacestandards.org</a>>, Ramon Krosley <<a href="mailto:r.krosley@andropogon.org" rel="nofollow" target="_blank">r.krosley@andropogon.org</a>>, Radulescu, Costin (US 9300) <<a href="mailto:cradule@jpl.nasa.gov" rel="nofollow" target="_blank">cradule@jpl.nasa.gov</a>>, Christian Stangl <<a href="mailto:christian.sta@googlemail.com" rel="nofollow" target="_blank">christian.sta@googlemail.com</a>>, Cheng, Shelbun K (US 312H) <<a href="mailto:shelbun.k.cheng@jpl.nasa.gov" rel="nofollow" target="_blank">shelbun.k.cheng@jpl.nasa.gov</a>>, Thompson, Paul B <<a href="mailto:PBTHOMPSON@qinetiq.com" rel="nofollow" target="_blank">PBTHOMPSON@qinetiq.com</a>>, he xiongwen <<a href="mailto:hexw501@hotmail.com" rel="nofollow" target="_blank">hexw501@hotmail.com</a>><br>Cc: SEA-SA <<a href="mailto:sea-sa@mailman.ccsds.org" rel="nofollow" target="_blank">sea-sa@mailman.ccsds.org</a>><br></div><br><br><div class="ydpf172cf6yiv9472090321ydp5dfc9e8yiv3700751578ydp6ebc143eyiv7984858979msg2161452005741930988">

I was poking about on the web to find good definitions for “ontology”, “conceptual model”, and related terms that we might want to include in the RASDS++ update. So I searched for "define ontology
in computer science". What came up was a definition that seemed workable, and also some related images that were provided.
