o CIM uses the term" property" for what LDAP terms an" attribute".

Moore, et al. Standards Track [Page 24]

RFC 3060 Policy Core Information Model February 2001

o CIM uses the array notation"[]" to indicate that a property is

multi-valued. CIM defines three types of arrays: bags (contents

are unordered, duplicates allowed), ordered bags (contents are

ordered but duplicates are allowed) and indexed arrays (contents

are ordered and no duplicates are allowed).

o CIM classes and properties are identified by name, not by OID.

o CIM classes use a different naming scheme for native

implementations, than LDAP. The CIM naming scheme is documented

in Appendix A since it is not critical to understanding the

information model, and only applies when communicating with a

native CIM implementation.

o In LDAP, attribute definitions are global, and the same attribute

may appear in multiple classes. In CIM, a property is defined

within the scope of a single class definition. The property may

be inherited into subclasses of the class in which it is defined,

but otherwise it cannot appear in other classes. One side effect

of this difference is that CIM property names tend to be much

shorter than LDAP attribute names, since they are implicitly

scoped by the name of the class in which they are defined.

There is also a notational convention that this document follows, to

improve readability. In CIM, all class and property names are

prefixed with the characters" CIM_". These prefixes have been

omitted throughout this document, with one exception regarding

naming, documented in Appendix A.
