The Security Vocabulary status

Hi Folks,

I ran across The Security Vocabulary
<https://web-payments.org/specs/source/vocabs/security.html> and it looks
like is has been stale since 2016. I also could not find the rdf
representation of the vocabulary -- the link to https://w3id.org/security#
redirects to https://web-payments.org/vocabs/security# and there is no
rdf+xml or ld+json content available.

Could someone please give an update on this effort? If dead, can you
recommend a similar project that is actively being maintained?

Thank you very much,

Ricardo Morin
