Re: [EP-tech] OAI Harvesting

Hi James,
That's an 'interesting' set setup. The default (commented-out) offering for that set doesn't have the department.

At a guess, it might have been added to create some disambiguation between authors of the same name, but in different departments - but that makes no sense, as it's using their IDs, not names.



To answer your question - it looks like a data-quality issue.

The following are *not* the same thing:

setName             Person = Molecular and Clinical Pharmacology

setSpec                706572736F6E3D4D6F6C6563756C617220616E6420436C696E6963616C20506861726D61636F6C6F6779

 

setName             Person = Molecular and clinical pharmacology

setSpec                706572736F6E3D4D6F6C6563756C617220616E6420636C696E6963616C20706861726D61636F6C6F6779

 

setName             Person = Department of Molecular and Clinical Pharmacology

setSpec                706572736F6E3D4465706172746D656E74206F66204D6F6C6563756C617220616E6420436C696E6963616C20506861726D61636F6C6F6779

 

NB the 'setSpec' is just the name represented as characters

 

My guidance would be:

- feed your weblogs through a tool to analyse the OAI-PMH requests, and see who's using what. If no one is using the 'person' sets, I think removing their definitions would speed your OAI-PMH interface up. I guess they were added for a reason at some point though - hopefully someone somewhere will know something about them!

- (possibly - based on the above) remove the 'Department' from that set definition.

- add another set for 'divisions' based on the 'divisions' field you are using

- on your test server add some sets for testing (see Andy's email) - this is a very useful approach for testing RT2 J

 

Cheers,

John

Hi James,

When I was setting up RT2, I ignored the predefined sets in Elements, and created custom sets for testing and for production. I set up a cfg.d/zzz_symplectic_oai.pl, and split the production harvest into full-text-public, full-text-restricted, and full-text-none (metadata-only). I forget the thinking behind that split, but it does cover everything, I believe.

 

I’m not sure if $c->{oai}->{custom_sets}} is something that is set up and parsed by default, or if you might need to enable that first. It was there, and I could edit it, so I did.

push @{$c->{oai}->{custom_sets}}, { spec => "full_text_none", name => "full_text_none", filters => [

 

                { meta_fields => [ "full_text_status" ], value=>"none", match=>"IN", merge=>"ANY" },

                  { meta_fields => [ "eprint_status" ], value=>"archive", match=>"IN", merge=>"ANY" },  -- live records only, not in review or deleted

 

] };

 

 

 

push @{$c->{oai}->{custom_sets}}, { spec => "full_text_public", name => "full_text_public", filters => [

 

                { meta_fields => [ "full_text_status" ], value=>"public", match=>"IN", merge=>"ANY" },

                  { meta_fields => [ "eprint_status" ], value=>"archive", match=>"IN", merge=>"ANY" },

push @{$c->{oai}->{custom_sets}}, { spec => "full_text_restricted", name => "full_text_restricted", filters => [

                  { meta_fields => [ "eprint_status" ], value=>"archive", match=>"IN", merge=>"ANY" },

 

] };

 

 

For testing I had a variety of scratch sets, using named users, years, or lists of Eprint IDs:

 

e.g.

 

NAMED USER:

 

push @{$c->{oai}->{custom_sets}}, { spec => "symplectic_andy_email", name => "symplectic_andy_email", filters => [

 

                { meta_fields => [ "creators_id" ], value=>"andy REID lshtm", match=>"IN", merge=>"ALL" },

 

] };

Hi All,

 

We're setting up RT2 (Elements) at the moment and working through some bugs. This is not a specific EPrints problem, but I'm hoping the collective wisdom of those here can provide some clarity...

 

In our OAI ListSets pages it has become apparent that we have duplicate sets. We appear to have a peculiar setup whereby we have :

 

$oai->{sets} = [
{ id=>"person", allow_null=>0, fields=>"contributors_id/editors_id/department" }

 

This puts department in the person set. We don't even use department in our current EPrints records (we have Divisions which I've spoken about a LOT previously). What I'm curious about is:

 

1) How do duplicate sets come about? I thought the idea of a set would be if items have the same value they would be in the same set.

 

2) Is there any easy way to identify the duplicate sets? Somebody from Symplectic that I'm working with was kind enough to point them out on our live repository and sure enough if I ctrl+f for "Molecular and Clinical Pharmacology" on https://livrepository.liverpool.ac.uk/cgi/oai2?verb=ListSets it appears twice.

 

I've tried to learn about OAI, but it does unfortunately make my brain scream because I just do not understand it properly.

 

Thanks,

James
