Version 3.1 (July 22, 2026)

This release extends the controlled vocabularies with unit-type information for demand types. The model data itself is unchanged.

Added

• Unit types in the demand-type vocabulary: the new canonical EDP_TYPES mapping records each demand type’s short acronym and the physical quantity it is measured in (UnitType), and the new UNIT_TYPES vocabulary enumerates the valid unit types: acceleration, speed, displacement, unitless, rotation, force, force_per_length, and pressure. Consumers (e.g., Pelicun 3.10+) can infer physical units for demand data from the vocabulary instead of maintaining hardcoded lists.

Changed

• EDP_to_demand_type is now derived from EDP_TYPES. Its content is identical to before, so existing consumers are unaffected.

Distribution

• Version 3.1 is published to PyPI as simcenter-dlml. The GitHub repository’s releases/latest continues to point to v2.1.0 for legacy Pelicun (≤3.9) compatibility.
