Tapalog, a Catalog Maker for Clicking Through Diagrams

Field notes

Catalogs are assembled by placing hotspots over an image and attaching data to each location, then saved as local .ecatm SQLite files for offline viewing. The homepage demonstrates the format with anonymized exploded-view truck-part diagrams and a smaller furniture catalog, and lists applications for Windows, Linux, macOS, and Chromebook. It also describes an optional self-hosted collaboration server and a classroom workflow that avoids student accounts and cloud storage.
