STIX_1_1_Updater
¶ Updates STIX v1.1 content to STIX v1.1.1.
The following update operations are performed:
- The
Source
field under instances ofStatementType
andConfidenceType
are translated fromControlledVocabularyStringType
instances toIdentityType
instances. The original value becomes theName
field of theIdentityType
instance. - The
Source
field underIndicatorType/Sightings/Sighting
is converted into an instance ofIdentityType
where the original value becomes the value of theName
field. - The
Related_Campaigns
field underIndicatorType
is converted from a flat list ofRelatedCampaignType
instances into an instance ofGenericRelationshipListType
. - Instances of the
GeneralTestMechanismType
extension have empty, optional fields removed. - Instances of
AvailabilityLossVocab-1.0
are upgraded toAvailabilityLossVocab-1.1
Note
All fields can be translated between STIX v1.1 and STIX v1.1.1.
-
check_update
(root, options=None)¶ Determines if the input document can be upgraded.
Parameters: - root – The XML document. This can be a filename, a file-like object,
an instance of
etree._Element
or an instance ofetree._ElementTree
. - options (optional) – A
ramrod.UpdateOptions
instance. IfNone
,ramrod.DEFAULT_UPDATE_OPTIONS
will be used.
Raises: UnknownVersionError
– If the input document does not have a version.InvalidVersionError
– If the version of the input document does not match the VERSION class-level attribute value.UpdateError
– If the input document contains fields which cannot be updated or constructs with non-unique IDs are discovered.
- root – The XML document. This can be a filename, a file-like object,
an instance of
-
clean
(root, options=None)¶ Removes disallowed elements from root and remaps non-unique IDs to unique IDs for the sake of schema-validation.
Removed items can be retrieved via the
removed
attribute on the return value:>>> results = updater.clean(root) >>> print(results.removed) (<Element at 0xffdcf234>, <Element at 0xffdcf284>)
Items which have been reassigned IDs can be retrieved via the
remapped_ids
attribute on the return value:>>> results = updater.clean(root) >>> print(results.remapped_ids) {'example:Observable-duplicate': [<Element {http://cybox.mitre.org...
Note
This does not remap
idref
attributes to new ID values because it is impossible to determine which entity theidref
was pointing to.Parameters: - root – The XML document. This can be a filename, a file-like object,
an instance of
etree._Element
or an instance ofetree._ElementTree
. - options (optional) – A
ramrod.UpdateOptions
instance. IfNone
,ramrod.DEFAULT_UPDATE_OPTIONS
will be used.
Returns: An instance of
ramrod.UpdateResults
.- root – The XML document. This can be a filename, a file-like object,
an instance of
-
get_version
(package)¶ Returns the version of the package
STIX_Package
element by inspecting itsversion
attribute.
-
update
(root, options=None, force=False)¶ Attempts to update root to the next version of its language specification.
If force is set to True, items may be removed during the translation process and IDs may be reassigned if they are not unique within the document.
Note
This does not remap
idref
attributes to new ID values because it is impossible to determine which entity theidref
was pointing to.Removed items can be retrieved via the
removed
attribute on the return value:>>> results = updater.update(root, force=True) >>> print(results.removed) (<Element at 0xffdcf234>, <Element at 0xffdcf284>)
Items which have been reassigned IDs can be retrieved via the
remappped_ids
attribute on the return value:>>> results = updater.update(root, force=True) >>> print(results.remapped_ids) {'example:Observable-duplicate-id-1': [<Element {http://cybox.mitre...
Parameters: - root – The XML document. This can be a filename, a file-like object,
an instance of
etree._Element
or an instance ofetree._ElementTree
. - options – A
ramrod.UpdateOptions
instance. IfNone
,ramrod.DEFAULT_UPDATE_OPTIONS
will be used. - force – Forces the update process to complete by potentially removing untranslatable xml nodes and/or remapping non-unique IDs. This may result in non-schema=conformant XML. USE AT YOUR OWN RISK!
Returns: An instance of
ramrod.UpdateResults
.Raises: UpdateError
– If untranslatable fields or non-unique IDs are discovered in root and force isFalse
.UnknownVersionError
– If the root node contains no version information.InvalidVersionError
– If the root node contains invalid version information (e.g., the class expects v1.0 content and the root node contains v1.1 content).
- root – The XML document. This can be a filename, a file-like object,
an instance of
