Broken link: w3id link to MIxS terms is broken

[eecavanna]

The schema contains this (this is an excerpt):

  geo_loc_name:
    # ...
    from_schema: http://w3id.org/mixs/terms
    # ...

Source: mixs.yaml

When I visit that URL (i.e. http://w3id.org/mixs/terms), I end up at an error page (at https://genomicsstandardsconsortium.github.io/mixs/terms):

There are 500+ occurrences of the string http://w3id.org/mixs/terms in that mixs.yaml file.
