[EP-tech] Re: Eprints to Omeka Harvest

[Ian Stuart]

Its not a complete solution - but I can tell you why its not working, 
and point you at some stuff to work out your own solution.

When you import data into Eprints (into any repository, doesn't matter 
what system) - you need to copies the information from whatever format 
the data is supplied in, into whatever format you have in your 
repository (basically, what fields you have in your database)

There are two parts to this... and one of those is more complicated still.

Part 1: What file have you been given?
If you have an XML file, then it probably just contains data, so you 
only need to "cross-walk" from whatever they have to whatever you need.
(note the "probably" - the XML could contain the files by being "clever" 
- but you can be clever back, and pull them out)

Part 2: Translating (cross-walking) from one format to another
it is very unlikely that you will get data in the format that your 
EPrints repository uses natively, so you need to somehow translate what 
your given into what you need.
COMPLICATION
You've said that what you're given is METS - METS is actually a format 
for transferring metadata... it doesn't actually say how the metadata is 
written out (encoded, or packaged).
You have discovered the METS importer that comes with EPrints - however 
this is specifically for the METS profile that has the metadata 
described in the format defined by DSpace... so the chances are that the 
Omeka data isn't packaged in the same way that DSpace does it.... which 
is why its not working!

SOLUTIONS
We all want solutions :)

What you need to do is write some code (sorry) that does the translation 
from whatever Omeka puts out to what EPrints understands.

As it happens, I can point you at code that reads METS, and translates 
it into EPrints.
For EPrints 3.2 - look at https://github.com/edina/RJ_Broker_Importer_3.2
For Eprints 3.3, try https://github.com/edina/RJ_Broker_2

Now - these are not direct solutions:
1) They are SWORD importers, so they have some assumptions that are 
different to a command-line based importer
2) They are for a METS metadata format that I made, so unlikely to match 
the Omeka format
.... but they ARE a good starting point, and they WILL help.
