Getting All Data Components That Detect A Technique

I am trying to use STIX & MitreAttackData in Python to create a list of data components for each MITRE technique.

Currently, I use a MitreAttackData (https://mitreattack-python.readthedocs.io/en/latest/mitre_attack_data/mitre_attack_data.html) object with the get_datacomponents_detecting_technique(stix_id) function to get all the data components that detect a given technique. I am using the up-to-date JSON file representing STIX data for this (https://raw.githubusercontent.com/mitre-attack/attack-stix-data/refs/heads/master/enterprise-attack/enterprise-attack.json). For each technique, it returns an empty list.

I noticed in the JSON file there is an x_mitre_data_source_ref for each data component in the JSON file, but it is empty for all data components. Additionally, the x_mitre_detection field for each of the attack patterns is also empty. How is the relationship between techniques (attack patterns) and data components possible without a linking reference? I imagine this is what is causing the empty lists.

I can get all data components from the MitreAttackData object, but I cannot get all data components that detect specific techniques. How can I use the enterprise-attack JSON file to do this, or do I need to use a different file and/or a different Python library?

Start by inspecting the enterprise-attack.json objects and the MitreAttackData.get_datacomponents_detecting_technique(stix_id) entry point. Trace how relationships between attack patterns and data components are represented, then compare that representation with the library's lookup logic. Done means identifying the supported data source or documenting the missing relationship data and expected lookup behavior.
