Thanks again for your interest and contributions to CAPEC!
Lead Cyber Security Engineer
The MITRE Corporation
MITREhas been working with DHS and the OASIS Cyber Threat Information (CTI) technical committee to develop STIX (Structured Threat Information eXpression) a standard for exchanging cyber
threat information. STIX 2.0, which was released in 2017, as a committee standard , is implemented as JSON objects. MITREhas set up a GitHub site  which contains
various cyber threat information content, expressed using the STIX standard, available to anyone.
In order to make CAPEC content more accessible, the CAPEC Attack Patters in STIX 2.0 format are available. This an alternative way to view CAPEC content – capec.mitre.org is still the primary source. They are available at that
site in the ‘capec’ subdirectory. Not all properties of a CAPEC Attack Pattern are converted, due to limitations of the STIX format and the complexity of some CAPEC properties. For more details on the conversion mapping see USAGE-CAPEC.md.
That documentation also includes instructions on how to use the python-stix2 API  to access this content programmatically.
