Construct an ObservationInfo from the supplied parameters.

Parameters:

• extensions (dict [str: PropertyDefinition], optional) – Optional extension definitions, indexed by extension name (without the ext_ prefix, which will be added by ObservationInfo).

• translator_class (MetadataTranslator-class, optional) – Optional translator class defining the extension properties. If provided, this can be used instead of extensions and will be stored in the instance for JSON round-tripping.

• **kwargs (Any) – Name-value pairs for any properties to be set. In the case of extension properties, the names should include the ext_ prefix.

Return type:

ObservationInfo

Raises:

• KeyError – Raised if a supplied parameter key is not a known property.

• TypeError – Raised if a supplied value does not match the expected type of the property.
