MATEExploring a process
The process page is the workspace for one log. Its tabs are URL-backed, so any view — a filtered event list, a variant, an activity — is a shareable link.
Process page layout#
The breadcrumb carries the name and the Overview tab opens with the stat strip (format, cases, events, variants, date range, import time); OCEL logs are also badged object-centric. The data tabs — Events, Variants, Activities (or Objects/Events/Relationships on an OCEL log) — stay disabled until the log is ready; Overview and Settings are always available. Banners appear for a mapping that needs review, an import in progress, and a failure.
| Tab | Contents |
|---|---|
| Overview | Stat strip, then the module grid with search; disabled cards state their reason. |
| Events | Virtualised event table with search, per-column filters, sorting, and edit mode. |
| Variants | Aggregated variants: cases, average duration, share of cases, last seen. |
| Activities | Activity list with event counts and editable display names. |
| Settings | Everything in log settings. |
OCEL logs swap the middle tabs for Objects, Events, and Relationships, driven by the log's own Parquet schema.
Events tab#
| Control | Behaviour |
|---|---|
| Cross-column search | Debounced 300 ms. |
| Missing-values switch | Shows only rows with empty cells. |
| Column filters | Operators per column type — string: contains, equals, is_null, is_not_null; numeric, duration, and datetime: equals, gte, lte, is_null, is_not_null; enum and boolean: equals, is_null, is_not_null. |
| Apply / Restore | Commits the filter to the log (re-running modules), or restores the unfiltered view. |
| Case chip | Arriving with ?case_id= restricts the table to that case. |
| Paging | 25, 50, 100, or 200 rows. |
Variants and activities#
The variants tab filters by activity and minimum case count, sorts by cases, duration, or recency, and shows each variant's share of all cases. Opening a variant gives its sequence, a duration histogram, attribute breakdowns, and the list of its cases. The activities tab lists each activity with its event count and lets you set a display name used across the app.
Cross-module navigation#
Wherever a module renders an activity or a variant, the label links into the matching view, carrying the standard drill parameters (activity, case, variant, object_type, ts_from/ts_to, view, metric; from/to name the two ends of a graph edge). That is what makes a chart a starting point rather than an endpoint.
