This document outlines the items of the OVAL System Characteristics XML schema that are independent of any specific family or platform. Each iten is an extention of a basic System Characteristics item defined in the core System Characteristics XML schema.
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.

This element holds information about specific entries in the LDAP directory. It extends the standard ItemType as defined in the oval-system-characteristics schema and one should refer to the ItemType description for more information.
Extends: oval-sc:ItemType
Child Elements Type MinOccurs MaxOccurs suffix oval-sc:EntityItemStringType 0 1 Each object in an LDAP directory exists under a certain suffix (also known as a naming context). A suffix is defined as a single object in the Directory Information Tree (DIT) with every object in the tree subordinate to it. relative_dn oval-sc:EntityItemStringType 0 1 The relative_dn field is used to uniquely identify an item inside the specified suffix. It contains all of the parts of the item's distinguished name except those outlined by the suffix.

Note that while an LDAP attribute can contain structured data where it is necessary to collect multiple related fields that can be described by the 'record' datatype, it is not always the case. It also is possible that an LDAP attribute can contain only a single value or an array of values. In these cases, there is not a name to uniquely identify the corresponding field(s) which is a requirement for fields in the 'record' datatype. As a result, the name of the LDAP attribute will be used to uniquely identify the field(s) and satisfy this requirement. If the LDAP attribute contains a single value, the 'record' will have a single field identified by the name of the LDAP attribute. If the LDAP attribute contains an array of values, the 'record' will have multiple fields all identified by the name of the LDAP attribute.

Child Elements Type MinOccurs MaxOccurs engine ind-sc:EntityItemEngineType 0 1 The engine entity identifies the specific database engine used to connect to the database. version oval-sc:EntityItemStringType 0 1 The version entity identifies the version of the database engine used to connect to the database. connection_string oval-sc:EntityItemStringType 0 1 The connection_string entity defines connection parameters used to connect to the specific database. sql oval-sc:EntityItemStringType 0 1 The sql entity holds the specific query used to identify the object(s) in the database. result oval-sc:EntityItemAnySimpleType 0 unbounded The result entity specifies the result(s) of the given SQL query against the database.

The textfilecontent_item looks at the contents of a text file (aka a configuration file) by looking at individual lines.
Extends: oval-sc:ItemType
Child Elements Type MinOccurs MaxOccurs filepath oval-sc:EntityItemStringType 0 1 The filepath element specifies the absolute path for a file on the machine. A directory cannot be specified as a filepath. path oval-sc:EntityItemStringType 0 1 The path element specifies the directory component of the absolute path to a file on the machine. filename oval-sc:EntityItemStringType 0 1 The filename entity specifies the name of the file (without the path) that is being represented. pattern oval-sc:EntityItemStringType 0 1 The pattern entity represents a regular expression that is used to define a block of text. Subexpression notation (parenthesis) is used to call out a value(s) to test against. For example, the pattern abc(.*)xyz would look for a block of text in the file that starts with abc and ends with xyz, with the subexpression being all the characters that exist inbetween. Note that if the pattern can match more than one block of text starting at the same point, then it matches the longest. Subexpressions also match the longest possible substrings, subject to the constraint that the whole match be as long as possible, with subexpressions starting earlier in the pattern taking priority over ones starting later. instance oval-sc:EntityItemIntType 0 1 The instance entity calls out which match of the pattern is being represented by this item. The first match is given an instance value of 1, the second match is given an instance value of 2, and so on. The main purpose of this entity is too provide uniqueness for different textfilecontent_items that results from multiple matches of a given pattern against the same file. line oval-sc:EntityItemStringType 0 1 The line element represents a line in the file and is represented using a regular expression. text oval-sc:EntityItemAnySimpleType 0 1 The text entity represents the block of text that matched the specified pattern. subexpression oval-sc:EntityItemAnySimpleType 0 unbounded The subexpression entity represents the value of a subexpression in the specified pattern. If multiple subexpressions are specified in the pattern, then multiple entities are presented. Note that the textfilecontent_state in the definition schema only allows a single subexpression entity. This means that the test will check that all (or at least one, none, etc.) the subexpressions pass the same check. This means that the order of multiple subexpression entities in the item does not matter.
This item stores information about OVAL Variables and their values.

Child Elements Type MinOccurs MaxOccurs var_ref ind-sc:EntityItemVariableRefType 0 1 The id of the variable. value oval-sc:EntityItemAnySimpleType 0 unbounded The value of the variable. If a variable represents and array of values, then multiple value elements should exist.
This item stores results from checking the contents of an xml file.

Child Elements Type MinOccurs MaxOccurs filepath oval-sc:EntityItemStringType 0 1 The filepath element specifies the absolute path for a file on the machine. A directory cannot be specified as a filepath. path oval-sc:EntityItemStringType 0 1 The path element specifies the directory component of the absolute path to a file on the machine. filename oval-sc:EntityItemStringType 0 1 The filename element specifies the name of the file. xpath oval-sc:EntityItemStringType 0 1 Specifies an Xpath expression describing the text node(s) or attribute(s) to look at. value_of oval-sc:EntityItemAnySimpleType 0 unbounded The value_of element checks the value(s) of the text node(s) or attribute(s) found. How this is used is entirely controlled by operator attributes.
