 == Relationships ==
+Currently, the CLARIN-D Centers use different means to represent relationships between resources.
+In the following, some of these representations are analyzed.
+
+=== HZSK ===
+ 
+HZSK represents all resources of a corpus in one CMDI record. Thus, the target of a relationship
+(<ResourceRef>) has always type (ResourceType) Resource. The individual resources are further specified
+in the component part of the CMDI record by refering to the <ResourceProxy> via its id attribute.
+
+Example:
+
+http://virt-fedora.multilingua.uni-hamburg.de/drupal/fedora/repository/cmdi:demo/cmdi/metadata.xml
+
+{{{
+<ResourceProxy id="ACDIMB865D8-D9BA-7F9B-E652-D00D960850B4">
+  <ResourceType mimetype="text/xml">Resource</ResourceType>
+  <ResourceRef>http://hdl.handle.net/11858/00-248C-0000-000E-0181-F</ResourceRef>
+</ResourceProxy>

+}}}
+
+=== BAS ===
+
+BAS represents the resources of a corpus by several CMDI records, and employs a variety of approaches to represent relationships:
+
+a. The relationship between the CMDI record for a corpus and its parts is specified explicitly in one direction by means of CMDI's built-in <isPartOf> element.
+b. Relationships with a target of type Resource are further specified in the component part of the CMDI record by referring to the <ResourceProxy> via its id attribute
+c. Relationships between individual components, such as from <media-file> to <media-session-actor> are represented by referring to the target's id attribute as well.
+
+Example: 
+
+https://clarin.phonetik.uni-muenchen.de/BASRepository/Public/Corpora/ZIPTEL/ZIPTEL.2.cmdi.xml
+
+<ResourceProxy id="c_0000000001">
+  <ResourceType mimetype="text/xml">Metadata</ResourceType>
+  <ResourceRef>https://clarin.phonetik.uni-muenchen.de/BASRepository/Public/Corpora/ZIPTEL/0001.2.cmdi.xml</ResourceRef>
+</ResourceProxy>

+or

+

+  <ResourceType mimetype="audio/raw">Resource</ResourceType>

+<media-file actor-ref="s_0000000001" ref="r_0000000001">
+  <Type>audio</Type><Quality>3</Quality>
+  <RecordingConditions>un-supervised answering of a question prompted via telephone</RecordingConditions>
+...
+</media-file>

+<media-session-actor id="s_0000000001">
+  <Role>question answering</Role> 
+  <Name>unspecified</Name>
+  <FullName>unspecified</FullName>
+  <Code>0001</Code>
+  ...
+</media-session-actor>
+
+=== IDS-Mannheim ===
+
+IDS-Mannheim represents resources by several CMDI records, and employs a variety of approaches to
+represent relationships:
+
+a. The first version of the historical newspaper corpus MKHZ represents relationships by <ResourceProxy> as well as OLAC-Dcmi-Terms elements such as <hasPart>, were both point to a PID (see for example http://repos.ids-mannheim.de/fedora/objects/clarind-ids:mkhz.000000/datastreams/CMDI/content)
+b. The second version of the historical newspaper corpus represents relationships by <ResourceProxy> and further specifies the semantics (and anchor text) of the relationship in the component part of the relationship (see for example http://repos.ids-mannheim.de/fedora/objects/clarin-ids:mkhz1.00000/datastreams/CMDI/content)
+c. Relationships in the corpora of spoken language are represented by ResourceProxy's only, and partOf relationships are further specified by means of CMDI's built-in <IsPartOf> element (see for example http://repos.ids-mannheim.de/fedora/objects/clarin-ids:folk.FOLK_S_00248.cmdi/datastreams/CMDI/content)
