At the moment I'm investigating the state of anatomical knowledge on Wikipedia/Wikidata. I noticed that the Foundational Model of Anatomy has a lot of useful data and while the ID's are usually referenced in Wikipedia the other information isn't used.

They say on their website:

The Foundational Model of Anatomy ontology (FMA) is OPEN SOURCE and available for general use.

But they also say:

To obtain a copy of the FMA database either click the "Get the FMA" link to the left or see: FMA Licenses.

The link to FMA Licenses is a broken link.

Is the database supposed to be really open and could be incorporated in Wikidata, or is that something that's not allowed?
