Hi Hilmar,<div><br></div><div>I spent a bit of time with Shawn and Ben working up two Darwin Core examples in OBOE. One example is a Darwin Core record of a specimen record, and the other is a Darwin Core record of a bird observation where they counted birds in a survey. They both should clarify how OBOE makes relationships clear and, in particular, makes the contextual relationships among different observations explicit (that were otherwise implicit in the Darwin Core record).</div>
<meta charset="utf-8"><div><br></div><div>The examples show how OBOE can flexibly incorporate terms from other ontologies that represent, for example, Entities and Characteristics. Note that I needed ontology classes in several areas, so I was lazy and just used a hypothetical 'foobar' ontology namespace for classes I needed. But the idea is that any proper OWL ontology that has the right mappings to OBOEs classes can be used.</div>

<div><br></div><div>This approach would be relevant to use case 1 on kelp/nitrogen and on use case DC2 on mammal observations.</div><div><br></div><div>Matt<br><br><div class="gmail_quote">On Mon, Nov 22, 2010 at 5:25 PM, Matt Jones <span dir="ltr"><<a href="mailto:jones@nceas.ucsb.edu">jones@nceas.ucsb.edu</a>></span> wrote:<br>

The model is general enough to accomodate these types of scientific observations, including specimen occurrence records, which are really just a specialized form of population survey in which the specimens are at times preserved. The crux, of course, is having an appropriate OBOE extension ontology that captures the essence of Darwin Core's model in OWL. We have not worked on that, and given the discussion of DwC concepts that has been occurring on tdwg-content over the last few weeks about the meaning of DwC terms, that might be a challenge.</div>
<div><br></div><div>Nevertheless, I'll try to work up a DwC record represented in OBOE as a point for discussion, and I'll send it here. And I'll probably add it to the use case pages on the SONet site somehow.</div>

Specimen records and species occurrence records are probably most typically transported in Darwin Core (DwC). Bob Morris and I are wondering whether anyone has thought yet about wrapping such a DwC record in an OBOE document.<br>
<br>
The OBOE paper doesn't provide a treatment of this, and my recollection from the TDWG Task Group meeting is that it hasn't been thought through yet. Also, looking at OBOE, DwC terms might be used to describe the Entity, but a direct wrapping does not seem obvious if not impossible. That's not to say that a DwC occurrence (an observation) couldn't be mapped to an equivalent OBOE document, but in my recollection such a mapping has not been defined yet.<br>
<br>
Can those who are more familiar with OBOE confirm this or provide pointers to where this question is being dealt with?<br>
