Codecademy fields in every export
The catalog record covers item identifier, title, item type distinguishing career path, skill path and course, canonical URL, subject, programming language or technology, level, stated duration and description.
Path structure is preserved as a parent with ordered components, because the route is the unit buyers compare. Components are frequently shared between paths, which is invisible in a flat export and material when totalling hours or assessing overlap.
Access tier is recorded per item: free, subscription or trial, with the date observed. Which content sits behind the subscription moves, and tracking that over time shows how a provider is repositioning without announcing it.
Technology and version tagging is collected carefully because it is where staleness hides. A course teaching a framework two major versions behind exists in the catalog and is a coverage gap in practice, and only the tag plus the update date reveals it.
Then the context fields: prerequisites where stated, certificate offering, ratings and enrolment signals where published, and the collection timestamp on every row.
