NewDataType encodes a 'SimpleDataTypeEnumeration' into an int.

NewObjectMatchType encodes a 'ExistenceEnumeration' value (used in tests for object assertions) into an int.

NewObjectStateEvrString produces a string with 'op' and 'evr' encoded as op|evr This is just one possible children of <dpkginfo_state>, that said all deb package tests are written against evr strings see: https://oval.mitre.org/language/version5.10.1/ovaldefinition/documentation/oval-definitions-schema.html#EntityStateEVRStringType.

NewObjectStateSimpleValue produces a string with 'datatype', 'op' and 'val' encoded as dtype|op|val.

NewObjectStateString produces a string with 'op' and 'value' encoded as op|value.

NewOperationType encodes an 'OperationEnumeration' into an int.

NewOperatorType encodes an 'OperatorEnumeration' into an int.

NewRhelResult is the result of parsing an OVAL file that targets a Rhel based distro.

NewStateMatchType encodes an 'CheckEnumeration' into an int.

NewUbuntuResult is the result of parsing an OVAL file that targets an Ubuntu distro.

ReplaceFedoraOSVersion Replaces `version` with the equivalent RHEL version, this is so that we can use RHEL OVAL definitions when scanning/running tests - note that even though Fedora is the upstream of RHEL, there is no 1:1 mapping between Fedora's versions and RHEL (for example RHEL 6 is based on both Fedora 12 and 13) - so this is an approximation.

Criteria is used to express an arbitrary logic tree.

Definition is a container of one or more criteria and one or more vulnerabilities.

DpkgInfoTest encapsulates a Dpkg info test.

<rpmverifyfile_test> can target any file installed via RPM - but in the case of OVAL definitions for RHEL based systems, they are used to make assertions against the installed OS version.
