I noticed in https://github.com/spdx/license-list-XML/issues/1112 a SPDX ID request for OGDL-Taiwan-1.0 and was reminded that several other licenses that we’ve approved don’t have SPDX IDs, or our materials use a slightly different identifier.
Made a start at alignment on the conforming licenses page in https://github.com/okfn/opendefinition/pull/209
There are certainly other places, but that’s the most visible one.
