Split presenters at ";"

[Arnei]

It was brought to my attention that this was a feature in the previous admin ui, so this patch adds it back in.

When adding multiple presenters to an event in the metadata tab, you can now add multiple presenters at the same time by delimiting them with a ";". For example, writing "Pacman; Duck Hunt" would result in both "Pacman" and "Duck Hunt" being added as presenters. Will also work for other metadata fields that work the same way, e.g. contributers.

EDIT: With the lastest commit, the delimiter is not ";", but instead specified in the metadata catalog configuration (where all metadata catalog fields are specified). If no delimiter is specified, no splitting will take place.

How to test this

Can be tested as usual.

[github-actions]

Use docker or podman to test this pull request locally.

Run test server using develop.opencast.org as backend:

podman run --rm -it -p 127.0.0.1:3000:3000 ghcr.io/opencast/opencast-admin-interface:pr-1104

Specify a different backend like stable.opencast.org:

podman run --rm -it -p 127.0.0.1:3000:3000 -e PROXY_TARGET=https://stable.opencast.org ghcr.io/opencast/opencast-admin-interface:pr-1104

It may take a few seconds for the interface to spin up.
It will then be available at http://127.0.0.1:3000.
For more options you can pass on to the proxy, take a look at the README.md.

This patch enable splitting value by an ; on all metadata fields. It does not read the metadata catalog configuration property.{field-id}.delimiter value like documented in https://docs.opencast.org/r/17.x/admin/#configuration/metadata/ The side effect is, you can't use ; any more in any metadata field in Opencast.

[wsmirnow]

The delimiter configuration value will be parsed by Opencast backend and provided by metadata endpoints liek /admin-ng/event/new/metadata, /admin-ng/event/EVENTID/metadata.json, …. Example:

[
    {
        "flavor": "dublincore\/episode",
        "title": "EVENTS.EVENTS.DETAILS.CATALOG.EPISODE",
        "fields": [
            {
                "readOnly": false,
                "id": "title",
                "label": "EVENTS.EVENTS.DETAILS.METADATA.TITLE",
                "type": "text",
                "value": "",
                "required": true
            },
            {
                "delimiter": ";",
                "readOnly": false,
                "id": "contributor",
                "label": "EVENTS.EVENTS.DETAILS.METADATA.CONTRIBUTORS",
                "type": "mixed_text",
                "value": [],
                "required": false
            }
        ]
    }
]

This patch enable splitting value by an ; on all metadata fields.

I cannot reproduce that. As far as I can tell this really only affects metadata fields of the mixed_text type, which are "presenters" and "contributors" in the common event catalog. Can you describe in more details what is happening with the other metadata fields, any errors?

It does not read the metadata catalog configuration property.{field-id}.delimiter value like documented in https://docs.opencast.org/r/17.x/admin/#configuration/metadata/

I was not aware that this was configurable, thanks for telling me! I will make sure the new admin ui respects the configuration.
