Re: [EP-tech] Remove versions support from EPrints

CAUTION: This e-mail originated outside the University of Southampton.

Great, custom user role worked like a charm.

A related question: if a user make a revision inside its workarea and
then delete the first version record (he can), in the second version
record the "succeeds" field hold a reference to the deleted item.
Usually I set the "succeeds" field to NULL using a command line db
client. Is there a way to manage the "succeeds" fields using the web
interface? I'm thinking about the record interface which seems a low
level interface to the eprint record.

 My idea is to disable versioning for items in working area, but can
this be a problem for users that creates the entire chain of versions
and then publish all of it together?

Hi Yuri,

I have also experience the mis-use of the "New Version" button. Often
the conflation with the "Use as template".  I don't think how you
disable this button has changed much if at all between 3.3.15 and the
latest version of 3.4.  You could just hide the button from the
Actions tab by adding the following to a config file under the
archive's cfg/cfg.d/ directory:

$c->{plugins}->{"Screen::EPrint::NewVersion"}->{appears}->{eprint_actions}
= undef;

Alternatively, you could completely disable the screen plugin:

$c->{plugins}->{"Screen::EPrint::NewVersion"}->{params}->{disable} = 1;

I don't think there is any risk to completely disabling this screen
plugin, so I would probably go for the latter.  However, if you have a
specific case where editors (and admin) can create new versions but
regular users should not then you would not want to completely disable
this screen plugin.  In that case you probably want to remove a
standard user from having the following permissions:

eprint/inbox/derive_version:owner
eprint/buffer/derive_version:owner
eprint/archive/derive_version:owner
eprint/deletion/derive_version:owner

This can be done by adding the following to a configuration file
(starting "z_" to ensure it is loaded after user_roles.pl) in your
archives cfg/cfg.d/ file:

push @{$c->{user_roles}->{user}}, qw{
    -eprint/inbox/derive_version:owner
    -eprint/buffer/derive_version:owner
    -eprint/archive/derive_version:owner
    -eprint/deletion/derive_version:owner
};

Regards

Hi!

 EPrints 3.3.15 here.

 For our users, versions are confusing and often are misused. Often it
happens that the user make a mistake, submit to the buffer and then
(lazy) do a version to avoid reinserting the metadata again. So we find
there's a stale version linked to the good one and the buffer is also
filled with 2 items...

 We would like to hide the version functionality, at least for the
users. Then, as editor, we can link the real versions when we find there
are (using db queries, there's no other way I know).

 Thanks!
