IndicatorBaseTypeSTIX Common Schema

This type represents the STIX Indicator component. It is extended using the XML Schema Extension feature by the STIX Indicator type itself. Users of this type who wish to express a full indicator using STIX must do so using the xsi:type extension feature. The STIX-defined Indicator type is IndicatorType in the namespace. This type is defined in the indicator.xsd file or at the URL

Alternatively, uses that require simply specifying an idref as a reference to an indicator defined elsewhere can do so without specifying an xsi:type.


Field Name Type Description
@idoptional QName

Specifies a unique ID for this Indicator.

@idrefoptional QName

Specifies a reference to the ID of an Indicator specified elsewhere.

When idref is specified, the id attribute must not be specified, and any instance of this Indicator should not hold content.

@timestampoptional dateTime

Specifies a timestamp for the definition of a specific version of an Indicator. When used in conjunction with the id, this field is specifying the definition time for the specific version of the Indicator. When used in conjunction with the idref, this field is specifying a reference to a specific version of an Indicator defined elsewhere. This field has no defined semantic meaning if used in the absence of either the id or idref fields.
