<p>Hi David,<o:p></o:p></p>
<p>This is due to the code where the EPM data object is defined not being included.&nbsp; You may need to edit the file:<o:p></o:p></p>
<p>EPRINTS_PATH/flavours/pub_lib/inc<o:p></o:p></p>
<p>and add the line:<o:p></o:p></p>
<p>ingredients/bazaar<o:p></o:p></p>
<p>That said, I have checked backed and both EPrints 3.4 original release (i.e. 3.4.0) and 3.4.3 both have this line.&nbsp; Although the way the inc file is defined in 3.4.0 is semi-colon rather than new line separated for different paths in this inc file.&nbsp; If you
 do have an inc file that looks like:<o:p></o:p></p>
<p>flavours/pub_lib;site_lib;ingredients/bazaar;<o:p></o:p></p>
<p>It may be worth changing this to:<o:p></o:p></p>
<p class="MsoNormal">flavours/pub_lib<br>

ingredients/bazaar <o:p></o:p></p>

</div>
<div>
<p class="MsoNormal">In fact, if you do not have an EPRINTS_PATH/site_lib/ directory, I would remove that line altogether.&nbsp; I am pretty sure using the semi-colon separated syntax still works but it is worth eliminating all possible differences.&nbsp; I assume you
 have a&nbsp; non-empty directory at EPRINTS_PATH/ingredients/bazaar/?&nbsp; Also if you have mlocate install on your operating system it is worth checking that the following file exists and where it is located, (it should be at EPRINTS_PATH/ingredients/bazaar/plugins/EPrints/DataObj/EPM.pm):<o:p></o:p></p>
