Broken links #69
Description
Hi!
I wanted to register more broken links at https://openmath.org/cd/
This is related to #63, #62 and #7.
The official W3C link checker is a good tool to check broken links: https://validator.w3.org/checklink

@saona-raimundo a pull request fixing some would be welcome, but it's not clear what to do in all cases.
Any page archiving sofware available 20 years ago is likely to have broken links
https://openmath.org/software/ for example links to
http://www.riaca.win.tue.nl/download/om/cd/editor/
which is 404, the wayback machine doesn't have it either.
We could simply delete the entry but that loses information in the historical record, or we could leave the entry but disable the link, or perhaps it is archived somwhere at a new url and we could update so the link works...
It would probably be good if at least the CDs link checked, but knowing it's broken and knowing how to fix it are not the same thing.

oh my initial comment was about external links but
https://openmath.org/cd/group5.html#homomorphism_by_generators
links to
stsfiles are broken. The html view is adding sts links always but several "experimntal" cd don't have this, I don't think I want to regnerate the cd presentation but I could generate "holding" pages saying "this sts file not yet available" which would be better than just getting the site 404 page.saona-raimundo commentedon Jun 28, 2022
I am happy to help, but I am not sure what to do in all cases.
Should I start a pull request with some fixes where it is easy to determine what to do?
Thank you for the quick answer!

yes that would be good thanks, meanwhile as you may have seen I generated stub html (actually markdown source) pages for any missing sts files so that links from html view of a CD to sts should not be broken now
