STIX Schema Development
NOTE: If you are looking for official releases of STIX, please see http://stixproject.github.io/releases/1.2/. The schemas in this respository (even the tagged releases) are NOT OFFICIAL, as there are a couple post-processing steps not covered in the files in this repository. If there are any inconsistencies between the files in this repository and the files on https://stixproject.github.io/, the files there take precedence.
Structured Threat Information eXpression (STIX) is a collaborative community-driven effort to define and develop a standardized language to represent structured cyber threat information. The STIX Language intends to convey the full range of potential cyber threat information and strives to be fully expressive, flexible, extensible, automatable, and as human-readable as possible. All interested parties are welcome to participate in evolving STIX as part of its open, collaborative community.
Please visit the STIX website for more information about the STIX Language.

Cloning the repository
This STIX schemas repository uses git submodules in order to include the CybOX schemas (which are a dependency of the STIX schemas).
git clone command will not retrieve these automatically, you'll end up with an empty cybox directory rather than the schemas. To fix this you need to initialize and then update the submodules by running:
git submodule init git submodule update
Alternatively, using the
--recursive flag when cloning the repository will automatically initialize and update the submodules.
Finally, any time you see that the cybox directory has been modified (when merging or pulling updates) you will need to run
git submodule update again to actually update the schemas themselves.
