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>

http://metadata.net/fusion/hyp124.ruleml</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>

<ht:/hypothesis>
