OCEL Builder

Writes an OCEL 2.0 log by hand, schema first, and edits existing ones. Declare the event types and object types with their typed attributes (string / integer / float / boolean / time); each type gets its own tab — only its rows, only its own columns, no unavailable cells — with Excel-style editing: keyboard navigation, a fill handle, clipboard paste, autocomplete on every id, type and qualifier. Object attributes may be static or time-dependent, with a Changes tab recording the values an attribute took and when. A "+ relation" button on every Events/Objects row opens a small dialog to link an existing object or create one on the spot, without leaving the row for the E2O/O2O sheet. “Edit log” opens an existing OCEL 2.0 log the same way, with per-sheet search and paging, and publishes the result as a new artifact that records the log it came from. Everything is validated as you type, with one-click repairs, and every issue points at the exact row and tab it is about.
