-Typically, data-producing EM applications would export such a description of their data resources to a common database (triple store), which can then be queried from consuming applications using standard APIs (e.g. RDF/SPARQL) and extract/export the data into standard formats, e.g. DOC, KML, or XLS.

+Again the example from the introduction:
+
+{{{#!xml
+<?xml version="1.0"?>
+<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
+         xmlns:hxl="http://hxl.humanitarianresponse.info/ns">

+    <hxl:source>http://www.example.org/eden/org/organisation/2</hxl:source>
+  </rdf:Description>
+  <rdf:Description rdf:about="http://www.example.org/eden/org/organisation/2">
+    <rdf:type>hxl:Organisation</rdf:Type>
+    <hxl:orgName>Example Organisation</hxl:orgName>
+  </rdf:Description>
+</rdf:RDF> 
+}}}
+
+Obviously, the structure of this example RDF/XML is very close to S3XML:
+
+{{{#!xml
+<?xml version="1.0"?>
+<s3xml>
+  <resource name="dvr_population"
+            url="http://www.example.org/eden/dvr/population/823">
+      <data field="person_count">127386</data>
+      <reference field="source_organisation_id"
+                 resource="org_organisation"
+                 uuid="urn:uuid:40391e28-4e8a-4021-bf29-a5dddd2e38f3"/>
+  </resource>
+  <resource name="org_organisation"
+            uuid="urn:uuid:40391e28-4e8a-4021-bf29-a5dddd2e38f3"
+            url="http://www.example.org/eden/org/organisation/2">
+    <data field="name">Example Organisation</data>
+  </resource>
+</s3xml>
+}}}
+
+...so that we should be able to use our in-line XSLT transformation capabilities to convert S3XML into HXL.

+A proof-of-concept XSLT template has been implemented for the project_activity resource.
