The following is a description of the elements, types, and attributes that compose the Junos-specific system characteristic items found in Open Vulnerability and Assessment Language (OVAL). Each item is an extension of the standard item element defined in the Core System Characteristic Schema. Through extension, each item inherits a set of elements and attributes that are shared amongst all OVAL Items. Each item is described in detail and should provide the information necessary to understand what each element and attribute represents. This document is intended for developers and assumes some familiarity with XML. A high level description of the interaction between the different tests and their relationship to the Core System Characteristic Schema is not outlined here. This schema was originally developed by David Solin at jOVAL.org. The OVAL Schema is maintained by The MITRE Corporation and developed by the public OVAL Community. For more information, including how to get involved in the project and how to submit change requests, please visit the OVAL website at http://oval.mitre.org.

Stores information about the existence of a particular line in the JunOS config file, under the global context. Stores the resulting configuration data provided by the execution of a specific show command. The version_item holds information about the version of a particular component of the JunOS operating system. It extends the standard ItemType as defined in the oval-system-characteristics schema and one should refer to the ItemType description for more information. Stores the result of the application of an XPATH query applied to the JunOS configuration data provided by the execution of a specific show command, which has been piped to "display xml".
