Generic helpers for ord_schema, including common message types.



Wrappers and utilities for handling protocol buffers in Python.

class ord_schema.frozen_message.FrozenMessage(_message: MutableMapping | Message)

Bases: Mapping

Container for a protocol buffer that does not allow edits.


  • For standard scalar values, it is not possible to distinguish between default values and explicitly set values that match the default. If the default is a valid value, add the optional label to the field. See https://github.com/Open-Reaction-Database/ord-schema/pull/174.

  • For optional scalar values and all submessage fields, exceptions are raised if the user attempts to access an undefined attribute (AttributeError), access an undefined map key (KeyError), or set any attribute or map value (dataclasses.FrozenInstanceError).

  • I considered adding a raise_on_error option that would return None instead of raising AttributeError or KeyError when requesting unset values. However, this breaks the guarantee that hasattr returns False for unset optional scalar values and submessages.


Logging utilities.

ord_schema.logging.get_logger(name: str, level: int = 20) Logger

Creates a Logger.

Functions for creating Datasets by enumerating a template with a spreadsheet.

Generates a Dataset by enumerating a template reaction.

Converts a united message into another united message of the same type, but with different units.

  • message – a message with units, e.g., Mass, Length.

  • new_units – the desired units of the new message, expressed either as a string or an integer (ENUM value). Use of a string is recommended due to the ambiguity of using ENUM values; for example, Mass.GRAM == Time.MINUTE.


A new message with units, e.g., Mass, Length.

Template function for validating custom messages in the reaction_pb2.

Messages are not validated to check enum values, since these are enforced by the schema. Instead, we only check for validity of items that cannot be enforced in the schema (e.g., non-negativity of certain measurements, consistency of cross-referenced keys).

Note that the message may be modified in-place with any unambiguous changes needed to ensure validity.

  • message – A message to validate.

  • recurse – A boolean that controls whether submessages of message (i.e., fields that are messages) should also be validated. Defaults to True.

  • raise_on_error – If True, raises a ValidationError exception when errors are encountered. If False, the user must manually check the return value to identify validation errors.

  • options – ValidationOptions.
