TSL/ATS calulation does not work properly

[stefanCCS]

According to 'expectation' and source code here
https://github.com/kitodo/kitodo-production/blob/master/Kitodo/src/main/java/org/kitodo/production/process/TitleGenerator.java#L103
I would expect, that TSL/ATS is build as combination of Author and Title.
My document (PPN 1022427806) has both, as you can see here
Haupttitel:

Verfasser:

==> But, TSL/ATS is created out of Title only (after pressing "Zahnrad":

==> Please check, if there is something wrong (in my assumptions or in source code)

@stefanCCS can this be closed?

This could be related to #5207 and #5208 - it's sound familiar for me.

@henning-gerhardt :

I think, here is the problem, that not the "old" author fields (without metadata groups) can be used for the generation of ATS (author title schlüssel).
Due to the implementation of the metadata groups for personal and cooperation, the new fields must be assessed to create the ATS correctly according to the former times. That could be difficult, because the fields can be defined very flexible.

It could discussed, if a division in TSL and ATS is still necessary, or if the creation of TSL without information of the author is sufficient.

@andre-hohmann : In 2.x the following behavoiur is implemented: if there is no author given then the tls/ats is only build by title information. If there is an author a part of the tls/ats is builded with this author information. There is no requirement from where the title nor author is comming. But in this issue and maybe in the related: no tls/ats is build at all! So its looks for me that this method is not called or called with an empty title and author.

@henning-gerhardt:
I think the TSL is generated, but without author-information:

But, TSL/ATS is created out of Title only (after pressing "Zahnrad"

The following issues must be examined seperately, escpecially, because existing functionality have been los.

• TSL/ATS is not created and validated anymore during metadata import #5207
• TSL/ATS is not created for children processes without an own title anymore  #5208

@stefanCCS can this be closed?

@Kathrin-Huber : Following the discussions here, it does not look like, that this can be closed.
But, I do not know the details - so, please decide, how to go on ...

[andre-hohmann]

Maybe, this can be solved by the following use-keys, which were probably defined by @matthias-ronge. I have not applied yet.

• use="authorLastName" Der Wert wird als Nachname des Autors verwendet, um den Autortitelschlüssel zu bilden.
• use="title" Dieses Feld wird als Titel zur Bildung des Autor-Titel-Schlüssels verwendet.
