<p class="MsoNormal"><span lang="EN-GB"><o:p>&nbsp;</o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">we are looking for a way to interlink different versions of an item (&#8220;version thread / tree&#8221;) that are related to each other but not necessarily in a successor-predecessor relationship. &nbsp;A common use case example is a
 (working) paper or a conference/workshop item that is revised and published later as a journal article. Yet using the metadata field &#8216;succeeds&#8216; is not appropriate in this case as both versions should be retained and not replaced; a &#8216;commentary&#8217; by EPrint Object
 definition doesn&#8217;t seem to apply neither. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p>&nbsp;</o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">We had a look f.i. at the DataCite metadata schema (<a href="http://schema.datacite.org/meta/kernel-3/doc/DataCite-MetadataKernel_v3.1.pdf">v3.1</a>) where this is implemented with &#8216;relationType&#8217; and controlled list values
 such as IsSupplementTo / Continues / IsVariantFormOf / IsOriginalFormOf etc. As an interim solution we were thinking of setting (external) links as &#8216;Related URLs&#8217;, however, there might be more clever ways to represent internal repository relations.
