<p class="phone">Jonathon from SRI: interest primarily in ISO 18026 (c.f.
SEDRIS) and whether it has relevance to deriving W3C geospatial standards</p>
<p class="phone">Bhavani and Alam from UT Dallas: Cybersecurity and GRDF</p>
<p class="phone">John Goodwin from OS: Ontologies from geospatial domain
knowledge,e.g. hydrology, topography.</p>
<p class="phone">Cathy Dolbear from OS: Team leader for linking geospatial
holdings to ontologies, including hydrology</p>
<p class="phone">Peisheng from GMU, working on translating semantic
representations of geospatial domain knowledge into workflows</p>

addressed by axioms?</p>
<p class="phone"><cite>Josh:</cite> Could open world problems be a result of
representing a feature "as a geometry" rather than "with a geometry".</p>
<p class="phone">John Goodwin: might look into DOLCE as well in terms of a
feature ontology</p>
<h3 id="item04">What should comprise a W3C geospatial ontology?</h3>
