CalDAVtabeller

CalDAVtabeller is a term used to describe tooling and workflows that convert data from CalDAV calendars into tabular representations suitable for analysis, reporting, or integration with databases and spreadsheets. The term is not a formal standard; it describes a practice rather than a specification, and its exact meaning may vary between projects.

Access to CalDAV calendars is obtained via the CalDAV protocol (RFC 4791) over HTTP or HTTPS, using standard authentication methods. A typical pipeline uses a CalDAV client to enumerate calendars, retrieve iCalendar data via REPORT or GET, and parse the iCalendar format (RFC 5545). The resulting data is normalized into a table schema, for example: event_uid, calendar_id, start_time, end_time, summary, location, description, recurrence_id, recurrence_rules, attendees, and status. Recurring events require expansion or storage of recurrence rules to support time-based queries.

Common use cases include analyzing scheduling patterns, resource management, workforce planning, or migrating calendar data into data warehouses. Export formats often include CSV, JSON, or direct SQL inserts, and tools may provide incremental syncing to keep tables up to date. Some projects integrate with existing ETL pipelines and business intelligence tools.

Considerations include data privacy and access control, handling time zones and daylight saving time, performance on large calendars, and handling of non-standard or corrupted calendar components. Because CalDAVtabeller is not a formal standard, implementations vary in supported features and data models, which can affect interoperability and consistency across systems.
