Three source systems are merged. The LBCC repository rows come from
157 archived Hyrax work pages recovered from the Wayback Machine — the
landing pages were captured even where the file bitstreams were not, and their
“Related url” metadata field is what identified the upstream source of each
deposit. SkillsCommons rows come from the live DSpace 7 REST API at
library.skillscommons.org, where LBCC's DOL TAACCCT deposits still sit and the
old taaccct/ handles still resolve. External rows are open textbooks
traced to Open Oregon Pressbooks, the author's own site, and the Open Textbook Library.
Thumbnails are LBCC's own Hyrax derivatives replayed from the Wayback Machine where
they were captured, DSpace's generated thumbnails from SkillsCommons where they exist, and
first-page renders of the PDFs themselves otherwise. Course cartridges and course backups
have no visual form, so they get a typed placeholder.
Search covers filenames, course titles, full course descriptions, creators,
subjects, licences — and the extracted plain text of every document SkillsCommons had
already OCR'd or parsed. Quote a phrase to require it exactly.
