<h3 id="item01">OWL definition of GeoRSS and use in tagging HTML</h3>
<p> Geo ontology needs</p>
<p>Is GeoPriv constructing relationship and featuretype ontologies?</p>
<p>John Goodwin of OS expressed concern about establishing geospatial
ontologies best practices along with the ontology proposals</p>
<p>Suggestion to ask Jo Walsh about the ontology construction / RDF
definition</p>
<p>Discussing now the RDFa problem - elegant but invalid</p>
<p>Other options for tagging HTML in terms of both scraping methods and in
terms of ontology extraction. For example, would it be good to use
<object> for access by browser plug-ins (Openlayers plugin?) Should we
advocate <span> or <div> tags because they're valid XHTML, even
as a hack? </p>
<p>Or is <meta> , <link> cleaner although not currently
schema-valid? What would give maximum, well, ubiquity.</p>
<p>Schuyler: I would like to make sure we keep thing simple, and then scale
up, as timbl suggested</p>
<p>Joshua:: Yes, but one of the design challenges is to make it a good
foundation for those who want to build on it. An initial problem is
expressing "simply" something which encompasses both GeoRSS Simple and GeoRSS
GML It appears there is no inherently good way to do this. As with XML
Schema, we just have to define both serializations and then state in a
comment that they are equivalent.</p>
<p>Schuyler: what do you mean by "not inherently good"? You mean, expressing
GeoRSS Simple in a way that it appears to be a subset of GeoRSS GML?</p>
<p>Joshua: Either that or expressing GeoRSS Simple as a contraction, a
shorthand for GeoRSS GML.</p>
