Fixes #790

Problem

Multiple Rmd documentation source files and their generated HTML counterparts use http:// URLs for OHDSI services that fully support HTTPS. This is a security and consistency issue — modern browsers flag HTTP links, and the OHDSI ecosystem has long since migrated to HTTPS.

Solution

Replaced all http:// URLs with https:// equivalents across 6 Rmd source files and their 9 corresponding generated HTML documentation files (total: 15 files, 59 replacements).

Affected domains (all verified returning HTTP 200 over HTTPS):

  • athena.ohdsi.org — vocabulary search links
  • atlas-demo.ohdsi.org — ATLAS demo links
  • ohdsi.github.io — CDM refresh process links
  • forums.ohdsi.org — community forum links
  • omop-erd.surge.sh — interactive ER diagram
  • www.github.com/ohdsi — GitHub org and tool links
  • www.ohdsi.org — ATLAS web links

Verification

  • All HTTPS endpoints verified with curl -s -o /dev/null -w "%{http_code}" -L returning HTTP 200
  • grep -rn 'http://' --include='*.Rmd' rmd/ returns zero matches after fix
  • grep -rn 'http://' --include='*.html' docs/ returns zero OHDSI-domain matches after fix
  • No logic or rendering changes — pure URL protocol upgrade
