Code for stix-elevator now available in OASIS Open Repository

["Back, Greg" <gback@mitre.org>]

Hi everyone-
    
We are happy to announce that the initial version of stix-elevator (a tool for converting STIX 1.x XML to STIX 2.0 JSON) is available at https://github.com/oasis-open/cti-stix-elevator .
    
As stated in the README, the stix-elevator is a work-in-progress. It should be used to explore how existing STIX 1.x would potentially be represented in STIX 2.0. Using the current version of the elevator will provide insight to issues that might need to be mitigated to convert your STIX 1.x content.
    
***It should not be used in a production environment, and should not be considered final.***

The elevator has been tested against the relevant STIX 1.2 idioms (http://stixproject.github.io/documentation/idioms/) and another 391 STIX 1.1.1 documents we have access to.  Because these examples do not cover the majority of the STIX 1.x specification, we expect there are many other examples that the elevator will be unable to convert faithfully.  Please send us any such examples so we can improve the elevator.

The elevator will validate the converted output.  It will generate messages where the output does not adhere to the STIX 2.0 proposed standard.  Additionally, the elevator will also generate messages to indicate any issues found during the conversion. 
    
Any feedback on the tool can be provided on the email lists or via issues in the GitHub repo.
    
Additionally, we wanted to remind everyone of the other open repositories we've contributed to:
https://github.com/oasis-open/cti-stix2-json-schemas - Non-normative schemas and examples for STIX 2
https://github.com/oasis-open/cti-stix-visualization - Lightweight visualization for STIX 2.0 objects and relationships (see http://oasis-open.github.io/cti-stix-visualization)
https://github.com/oasis-open/cti-stix-validator - Validator for STIX 2.0 JSON normative requirements and best practices
https://github.com/oasis-open/cti-marking-prototype - Prototype for processing granular data markings in STIX
https://github.com/oasis-open/cti-pattern-validator - Validate patterns used to express Cyber Observable content in STIX Indicators
https://github.com/oasis-open/cti-pattern-matcher - Match STIX content against STIX patterns
    
We hope these tools are useful as we review and wrap up STIX 2.0, and encourage anyone to contribute bug fixes or new features.
    
Thanks,
