Creation of processes for volumes of multivolume works is not possible

[andre-hohmann]

Problem

It is not possible to create processes for volumes of multivolume works. There are two options working wrongly in different ways.

Option 1: import dephts =2

It is possible to

• Search the opac
• Import the metadata
• Generate the process title

It is not possible to:

• Save the process -> After clicking "Save" the massage "validata data" is shown, then nothing happens.

Option 1: import dephts =1

It is possible to

• Search the opac
• Import the metadata
• Generate the process title
• Save the process

However, only the process for the volume is created. Thus, there is no linking to the parent process.

Example-PPN of the volumes of multivolume works:

• 1428576223
• 142865559X
• 1449010784
• 142132640X
• 1421324458

Solution

It should be possible to create processes for the volumes of multivolume works.

The first option (with import depth=2) produces a NullPointerException with the following partial stack trace:

@matthias-ronge isn't this something you fixed not very long ago with #3357 ?

[matthias-ronge]

This error occurs because the ruleset has a <restriction division="MultiVolumeWork" unspecified="forbidden"> which does not <permit key="slub_serialGroup">, but the imported data contains a metadata group “slub_serialGroup”. Nevertheless, the ruleset should be tolerant of this, which it is not at the moment. This needs to be fixed.

[andre-hohmann]

I think an error- or warning-message describing the problem would be appropriate.

We have still the discussion, how to cope with differing metadata between import and ruleset. However, that will be discussed in another issue.

Closed as currently not reproducible.
