Appendix A: XML Representations for Hypotheses
A.1 The XML metadata recorded for a hypothesis
<ht:hypothesis>
<dc:Identifier>HYP124</dc:Identifier>
<dc:Creator>Graeme Auchterlonie</dc:Creator>
<dc:Date>2004/03/12</dc:Date>
<ht:statement>

<ht:exhibit>Presentation124</ht:exhibit>
<ht:background>A certain pattern in catalyst density and substrate width was noticed on the edges of fuel cells with efficiency >=70%
</ht:background>
<ht:outcome>positive</ht:outcome>
<ht:explanation>This density and width allows optimum gas permeation.</ht:explanation>
