Subject: cti-stix-elevator 2.1 released
We just published cti-stix-elevator version 2.1 on PyPi . The source code is available at . read-the-docs documentation is available at .
One new feature in this release, enabling the use of custom properties for properties missing from STIX 2.x, needs further discussion. The elevator tries to retain as much information from the STIX 1.x content as possible. Previously, if a STIX 1.x property did not exist in STIX 2.x, the elevator provided an option to include that content in the description property. This was the default behavior, which could be disabled.
As the use of STIX 2.x has evolved, the use of custom properties had been more generally accepted. This version of the elevator provides an additional option for how to handle âmissingâ properties. The previous option --no-squirrel-gaps has been replaced by the option
--missing-policy, which has three possible values:
An additional new option is provided to work in conjunction with the --missing-policy option, when its value is use-custom-properties. This option, --custom-property-prefix, allows for a prefix for the name of the custom properties. As described in the STIX specification document:
Custom Property names SHOULD start with âx_â followed by a source unique identifier (such as a domain name with dots replaced by underscores), an underscore and then the name. For example, x_example_com_customfield
The default value for this option is âelevatorâ.
