 == Introduction ==

+[http://hxl.humanitarianresponse.info HXL] is a shared vocabulary for [http://linkeddata.org Linked Data] for the humanitarian domain.
 
+Linked data use [http://en.wikipedia.org/wiki/Uniform_resource_identifier URI]s to identify data resources, and [http://en.wikipedia.org/wiki/Resource_Description_Framework RDF] statements (triples) to describe their relationships.
+
+Example:
+
+{{{#!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">
+  <rdf:Description rdf:about="http://www.example.org/eden/dvr/population/823">
+    <rdf:type>hxl:IDP</rdf:type>
+    <hxl:personCount>127386</hxl:personCount>
+    <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> 
+}}}
+
+This example encodes the RDF statements: 
+
+- ''The resource at'' {{{http://www.example.org/eden/dvr/population/823}}} => ''is a'' rdf:type => ''Internally Displaced Population'' hxl:IDP
+- ''The resource at'' {{{http://www.example.org/eden/dvr/population/823}}} => ''has a'' hxl:personCount => 127386
+- ''The resource at'' {{{http://www.example.org/eden/dvr/population/823}}} => ''comes from'' hxl:source => http://www.example.org/eden/org/organisation/2
+
+...where the latter refers to the resource described in the next RDF statements:
+
+- ''The resource at'' {{{http://www.example.org/eden/org/organisation/2}}} => ''is a'' rdf:type => rdf:resource hxl:Organisation.
+- ''The resource at'' {{{http://www.example.org/eden/org/organisation/2}}} => ''has'' orgName => "Example Organisation".
+
+(Note that this RDF/XML example is only one possible notation)
+
+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 export the data into standard formats, e.g. DOC, KML, or XLS.
+
+The purpose of this BluePrint is to define the role of Eden as HXL exporting application, or as triple store with RDF/SPARQL API or as HXL consumer. 
+
+The most obvious role for Eden at this point is that of the HXL exporter. A proof-of-concept prototype XSLT template has been implemented for the project_activity resource.
