Some links on https://www.openmath.org/cdnames/ are broken. This page claims it is autogenerated based, I assume based on the information in the CDs.
Based on what happens with orthpoly, I think this is caused by a CDName that does not match the filename.
What is the procedure to fix this ? Which is leading ? Filename or CDName ?
Affected CDs in contrib below:
Note: CDURL also contains the CDName in most of these cases
I found the first two manually and the other two by checking for broken links
