I hope this is the appropriate forum for this question. I've been tasked with determining the best way to try to create a hierarchy of tags such that clicking on a link to show items tagged "A" would allow you to then click on an additional tag to show you items tagged both "A" and "B."
Looking at the documentation, it looks like I can get at the information necessary to build such a plugin and my familiarity with WordPress makes me familiar with the idea of hooks and filters so I think I should be able to figure out a way to add my code to the basic flow of Omeka's processes.
But, I wanted to be sure that such a thing didn't already exist. Has anyone encountered such a thing before and, if so, it's it actively developed? Seeking a developer? Something else?
Thanks,
David Kees
