The stix-slider is a software tool for 'sliding' STIX 2.x JSON to STIX 1.x XML. Due to the differences between STIX 1.x and STIX 2.x, this conversion is best-effort only. During the conversion, stix-slider provides information on the assumptions it needs to make to produce valid STIX 1.x XML, and what information was not able to be converted.
The stix-slider is a work-in-progress. It should be used to explore how STIX 2.x content could potentially be represented in STIX 1.x. Using the current version of the slider will provide insight to issues that might need to be mitigated to convert your STIX 2.x content for use in application that accept only STIX 1.x content.
It should not be used in a production environment, and should not be considered final.
Please enter any comments on how to improve it into the issue tracker.
For more information, see the documentation on ReadTheDocs.
Python 3.8+
python-stix and its dependencies
Note
Make sure to use either the latest version of python-stix 1.1.1.x or 1.2.0.x, depending on whether you want to support STIX 1.1.1 or STIX 1.2.
python-stix2 >= 3.0.0
stixmarx >= 1.0.8
stix-validator >= 3.0.0
Install with pip:
$ pip install stix2-slider
This will install all necessary dependencies, including the latest version of python-stix.
If you need to support older STIX 1.1.1 content, install python-stix 1.1.1.x first:
$ pip install 'stix<1.2' $ pip install stix2-slider
You can also install the stix-slider from GitHub to get the latest (unstable) version:
$ pip install git+https://github.com/oasis-open/cti-stix-slider.git
It is recommended that you ensure that the input STIX 2.x file is valid before submitting it to the slider. Use the stix2-validator.
The slider comes with a bundled script which you can use to convert STIX 2.x content to STIX 1.x content:
usage: stix2_slider [-h] [--no-squirrel-gaps] [--validator-args VALIDATOR_ARGS] [-e ENABLE] [-d DISABLE] [-s] [--message-log-directory MESSAGE_LOG_DIRECTORY] [--log-level {DEBUG,INFO,WARN,ERROR,CRITICAL}] [--use-namespace USE_NAMESPACE] file stix2-slider v4.0.1 The stix2-slider is a work-in-progress. It should be used to explore how existing STIX 2.x would potentially be represented in STIX 1.x. Using the current version of the stix2-slider will provide insight to issues that might need to be mitigated so you can use an application that supports only STIX 1.x content. positional arguments: The input STIX 2.x document to be 'slid' to STIX 1.x.. optional arguments: -h, --help show this help message and exit --no-squirrel-gaps Do not include STIX 2.x content that cannot be represented directly in STIX 1.x using the description property. --validator-args VALIDATOR_ARGS Arguments to pass to stix-validator. Example: stix2_slider <file> --validator-args="--best- practices" -e ENABLE, --enable ENABLE A comma-separated list of the stix2-slider messages to enable. If the --disable option is not used, no other messages will be shown. Example: stix2_slider <file> --enable 250 -d DISABLE, --disable DISABLE A comma-separated list of the stix2-slider messages to disable. Example: stix2_slider <file> --disable 212,220 -s, --silent If this flag is set. All stix2-slider messages will be disabled. --message-log-directory MESSAGE_LOG_DIRECTORY If this flag is set, all stix2-slider messages will be saved to file. The name of the file will be the input file with extension .log in the specified directory. Note, make sure the directory already exists. Example: stix2_slider <file> --message-log-directory "../logs" --log-level {DEBUG,INFO,WARN,ERROR,CRITICAL} The logging output level. --use-namespace USE_NAMESPACE Override the 'example' namespace with the provided one. The format is the prefix, namespace uri and optionally the schema location separated by a space. Example: stix2_slider <file> --use-namespace="example http://example.com" Refer to slider_log_messages.rst for all stix2-slider messages. Use the associated code number to --enable or --disable a message. By default, the stix2-slider displays all messages. Note: disabling the message does not disable the functionality.
You can also use this library to integrate STIX 'sliding' into your own tools. You can slide a STIX 2.x file:
from stix2slider import slide_file from stix2slider.options import initialize_options initialize_options() results = slide_file("stix_file.json") print(results)
Additionally, a similar method exists to accept a string as an argument:
from stix2slider import slide_string from stix2slider.options import initialize_options initialize_options() results = slide_string("...") print(results)
To set options, use set_option_value, found in options.py.
This GitHub public repository ( https://github.com/oasis-open/cti-stix-slider ) was was created at the request of the the OASIS Cyber Threat Intelligence (CTI) TC as an OASIS TC Open Repository to support development of open source resources related to Technical Committee work.

Statement of Purpose for this OASIS TC Open Repository (cti-stix- slider) as proposed and approved [bis] by the TC:
This GitHub public repository is provided to support version- controlled development of a Python "slider" application which will convert STIX 2.x content to STIX 1.x content.
