### Technical stuff

* introduce module `wikis` in code base

* new model `WikiIntegration`

* 2 sub models: `XWikiWikiIntegration`, `InternalWikiIntegration`

* XWiki

* insert URL to wiki (in XWiki an instance can host multiple wikis) Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * Begin of the insertionalternative: URL to wiki instance and then selecting and creating wikis from that wiki instance (new admin interaction)

* End of the insertion generate a UUID for identification from the other side (XWiki)

* maybe instead of having an identifier per wiki integration have an instance ID

* consume an identifier from XWiki to identify them

* Authentication strategy

* OIDC

* bidirectional OAuth2 Begin of the insertion

* existent model `Wiki`

* reworked to be the object referencing `WikiIntegration`

* replacing `Project` reference with `ProjectWiki` reference

* dropping status ❓

* new model `ProjectWiki`

* created when configuring a project to have access to a wiki

* `WikiPage` can only point to a `Wiki`, that has a `InternalWikiIntegration`

* `Wiki` needs to refer to its integration type when calling any queries or commands

End of the deletion ### Hints

* renaming Begin of the insertionan xwikiEnd of the insertion Begin of the deletion aEnd of the deletion wiki **could** work

* we would need to update all inline page links Begin of the insertion

* better: do not use URLs in description text, but use inline page link blocks &nbsp;- e.g. `[[wiki:page-id]]`End of the insertion
