A short, general question: What are the criteria that modules for Omeka S are published on the official site , other - in my opinion good - modules, like “Timeline” are only to be found at Github. Unfortunately I made the experience that modules are not to be found any more, if programmers close their Github account.
Would be great to see more/all stable modules on the official page.
In order to be included on the modules page, creators need to register their module using the link from the modules directory. We rely on module developers to self-report, and would welcome more module creators registering their modules for inclusion on the directory page. However, if a module developer decides not to register, there’s not much we can do.
