[EP-tech] Eprints Bazaar and "Unknown dataset: epm"
Hi David,
This is due to the code where the EPM data object is defined not being
included.? You may need to edit the file:
EPRINTS_PATH/flavours/pub_lib/inc
and add the line:
ingredients/bazaar
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.? 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.? If you do have an inc file that
looks like:
flavours/pub_lib;site_lib;ingredients/bazaar;
It may be worth changing this to:
flavours/pub_lib
site_lib
ingredients/bazaar
In fact, if you do not have an EPRINTS_PATH/site_lib/ directory, I would
remove that line altogether.? I am pretty sure using the semi-colon
separated syntax still works but it is worth eliminating all possible
differences.? I assume you have a? non-empty directory at
EPRINTS_PATH/ingredients/bazaar/?? 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):
locate DataObj/EPM.pm
I have also written some instructions for upgrading between versions of
3.4 at:

This may provide some assistance, although it does not make any
reference to the specific issue you reported.
