The DateObjectPropertyType is a type (extended from BaseObjectPropertyType) representing the specification of a single Object property whose core value is of type Date. This type will be assigned to any property of a CybOX object that should contain content of type Date and enables the use of relevant metadata for the property. In order to avoid ambiguity, it is strongly suggested that any date representation in this field include a timezone if it is known. As with the rest of the field, this should be formatted per the xs:date specification. Properties that use this type can express multiple values by providing them using a delimiter-separated list. The default delimiter is '##comma##' (no quotes) but can be overridden through use of the delimiter field. Note that whitespace is preserved and so, when specifying a list of values, do not include a space following the delimiter in a list unless the first character of the next list item should, in fact, be a space. For fields of this type using CybOX patterning, it is strongly suggested that the condition (pattern type) is limited to one of Equals, DoesNotEqual, GreaterThan, LessThan, GreaterThanOrEqual, LessThanOrEqual, ExclusiveBetween, or InclusiveBetween. The use of other conditions may lead to ambiguity or unexpected results. When evaluating data against a pattern, the evaluator should take into account the precision of the field (as given by the precision attribute) and any timezone information that is available to perform a data-aware comparison. The usage of simple string comparisons is discouraged due to ambiguities in how precision and timezone information is processed.
| Field Name | Type | Description |
|---|---|---|
| @idoptional | QName |
The id field specifies a unique ID for this Object Property. |
| @idrefoptional | QName |
The idref field specifies a unique ID reference for this Object Property. When idref is specified, the id attribute must not be specified, and any instance of this property should not hold content unless an extension of the property allows it. |
| @datatypeoptional | DatatypeEnum |
This attribute is optional and specifies the expected type for the value of the specified property. |
| @appears_randomoptional | boolean |
This field is optional and conveys whether the associated object property value appears to somewhat random in nature. An object property with this field set to TRUE need not provide any further information including a value. If more is known about the particular variation of randomness, a regex value could be provided to outline what is known of the structure. |
| @is_obfuscatedoptional | boolean |
This field is optional and conveys whether the associated Object property has been obfuscated. |
| @obfuscation_algorithm_refoptional | anyURI |
This field is optional and conveys a reference to a description of the algorithm used to obfuscate this Object property. |
| @is_defangedoptional | boolean |
This field is optional and conveys whether the associated Object property has been defanged (representation changed to prevent malicious effects of handling/processing). |
| @defanging_algorithm_refoptional | anyURI |
This field is optional and conveys a reference to a description of the algorithm used to defang (representation changed to prevent malicious effects of handling/processing) this Object property. |
| @refanging_transform_typeoptional | string |
This field is optional and specifies the type (e.g. RegEx) of refanging transform specified in the optional accompanying refangingTransform property. |
| @refanging_transformoptional | string |
This field is optional and specifies an automated transform that can be applied to the Object property content in order to refang it to its original format. |
| @observed_encodingoptional | string |
This field is optional and specifies the encoding of the string when it is/was observed. This may be different from the encoding used to represent the string within this element. It is strongly recommended that character set names should be taken from the IANA character set registry (https://www.iana.org/assignments/character-sets/character-sets.xhtml). This field is intended to be applicable only to fields which contain string values. |
| @conditionoptional | ConditionTypeEnum |
This field is optional and defines the relevant condition to apply to the value. |
| @is_case_sensitiveoptional | boolean |
The is_case_sensitive field is optional and should be used when specifying the case-sensitivity of a pattern which uses an Equals, DoesNotEqual, Contains, DoesNotContain, StartsWith, EndsWith, or FitsPattern condition. The default value for this field is "true" which indicates that pattern evaluations are to be considered case-sensitive. |
| @apply_conditionoptional | ConditionApplicationEnum |
This field indicates how a condition should be applied when the field body contains a list of values. (Its value is moot if the field value contains only a single value - both possible values for this field would have the same behavior.) If this field is set to ANY, then a pattern is considered to be matched if the provided condition successfully evaluates for any of the values in the field body. If the field is set to ALL, then the patern only matches if the provided condition successfully evaluates for every value in the field body. |
| @delimiteroptional | string |
The delimiter field specifies the delimiter used when defining lists of values. The default value is "##comma##". |
| @bit_maskoptional | hexBinary |
Used to specify a bit_mask in conjunction with one of the defined binary conditions (bitwiseAnd, bitwiseOr, and bitwiseXor). This bitmask is then uses as one operand in the indicated bitwise computation. |
| @pattern_typeoptional | PatternTypeEnum |
This field is optional and defines the type of pattern used if one is specified for the field value. This is applicable only if the Condition field is set to 'FitsPattern'. |
| @regex_syntaxoptional | string |
This field is optional and defines the syntax format used for a regular expression, if one is specified for the field value. This is applicable only if the Condition field is set to 'FitsPattern'. Setting this attribute with an empty value (e.g., "") or omitting it entirely notifies CybOX consumers and pattern evaluators that the corresponding regular expression utilizes capabilities, character classes, escapes, and other lexical tokens defined by the CybOX Language Specification. Setting this attribute with a non-empty value notifies CybOX consumers and pattern evaluators that the corresponding regular expression utilizes capabilities not defined by the CybOX Language Specification. The regular expression must be evaluated through a compatible regular expression engine in this case. |
| @has_changedoptional | boolean |
This field is optional and conveys a targeted observation pattern of whether the associated field value has changed. This field would be leveraged within a pattern observable triggering on whether the value of a single field value has changed. |
| @trendoptional | boolean |
This field is optional and conveys a targeted observation pattern of the nature of any trend in the associated field value. This field would be leveraged within a pattern observable triggering on the matching of a specified trend in the value of a single specified field. |
| @precisionoptional | DatePrecisionEnum |
The precision of the associated time. If omitted, the default is "day", meaning the full field value. Digits in the date that are required by the xs:date datatype but are beyond the specified precision should be zeroed out. When used in conjunction with CybOX patterning, the pattern should only be evaluated against the target up to the given precision. |
