Migrate to Kitodo.Presentation 4

[dvoracek-slub]

This PR attempts to finish the migration to Kitodo.Presentation 4 and Extbase/Fluid, and does some maintenance and fixes along the way. When merged, this resolves #201 and #205.

The migration relies on the following PRs to other repos:

• https://github.com/kitodo/kitodo-presentation/pull/844 (Needed to replace the custom calendar plugin)
• https://github.com/slub/slub_digitalcollections/pull/47

So to test this:

• Checkout the Kitodo and Digital Collections PRs. (There's also https://github.com/dvoracek-slub/kitodo-presentation/tree/dev-dfgviewer.)
• https://github.com/slub/ddev-dfgviewer/pull/2 is an update to the default DDEV system.
• https://github.com/dvoracek-slub/ddev-dfgviewer-dist/ may be used to easily test a clean install.

Questions:

• language.typoscript has a language condition that looks obsolete to me (when using website language and site configuration). Is this right?

• How should localization of metadata labels and structures be handled? In principle, they would work if the following is done:

  • Create a translation of the viewer page.
  • If we want to include it in the initialization data dump, we could probably add it manually. (The impexp extension doesn't export page translations as of 10.4, see https://forge.typo3.org/issues/93470.)
  • Alternatively, we can just add a remark in the documentation to do this after install if wanted.
  • Remove the 0 suffixes of column index_name in tables tx_dlf_metadata and tx_dlf_structures.
  • I tried to change data.xml to avoid these suffixes on fresh install, but couldn't find a way so far. Even when reordering the entries, it looks like TYPO3's DataHandler::getUnique() won't detect the translated records as such because the l18n_parent doesn't yet have an ID.

  • What does seem to work is an SQL query like the following. This could possibly be integrated into the Kitodo backend module or documented.

    UPDATE `tx_dlf_metadata` a
    INNER JOIN `tx_dlf_metadata` b
    ON (a.l18n_parent = b.uid OR a.uid = b.l18n_parent)
    SET a.index_name = b.index_name
    WHERE a.index_name LIKE CONCAT(b.index_name, '0');
    
    UPDATE `tx_dlf_structures` a
    INNER JOIN `tx_dlf_structures` b
    ON (a.l18n_parent = b.uid OR a.uid = b.l18n_parent)
    SET a.index_name = b.index_name
    WHERE a.index_name LIKE CONCAT(b.index_name, '0');
