1.1 Glossary

This document uses the following terms:

address book: A collection of Address Book objects, each of which are contained in any number of address lists.

Address Book object: An entity in an address book that contains a set of attributes, each attribute with a set of associated values.

address list: A collection of distinct Address Book objects.

Augmented Backus-Naur Form (ABNF): A modified version of Backus-Naur Form (BNF), commonly used by Internet specifications. ABNF notation balances compactness and simplicity with reasonable representational power. ABNF differs from standard BNF in its definitions and uses of naming rules, repetition, alternatives, order-independence, and value ranges. For more information, see [RFC5234].

code page: An ordered set of characters of a specific script in which a numerical index (code-point value) is associated with each character. Code pages are a means of providing support for character sets and keyboard layouts used in different countries. Devices such as the display and keyboard can be configured to use a specific code page and to switch from one code page (such as the United States) to another (such as Portugal) at the user's request.

display template: A template that describes how to display or allow a user to modify information about an Address Book object.

entry ID: See EntryID.

local site: A directory services unit that defines the physical structure or topology of a local network.

message store: A unit of containment for a single hierarchy of Folder objects, such as a mailbox or public folders.

OAL data sequence number: An integer that is associated with offline address list (OAL) data that represents the generation number of this data. The value of the initial sequence number is "1". Each subsequent data generation process that produces a data set that is not identical to the previous data set is incremented by one.

offline address book (OAB): A collection of address lists that are stored in a format that a client can save and use locally.

offline address book (OAB) data file: A file that contains offline address book (OAB) version 4–specific data, as described in [MS-OXOAB].

offline address list (OAL): A portion of data that is in an offline address book (OAB) and is related to a single address list.

public folder: A Folder object that is stored in a location that is publicly available.

remote operation (ROP): An operation that is invoked against a server. Each ROP represents an action, such as delete, send, or query. A ROP is contained in a ROP buffer for transmission over the wire.

Root folder: The special folder that is the top-level folder in a message store hierarchy. It contains all other Folder objects in that message store.

SHA-1 hash: A hashing algorithm as specified in [FIPS180-2] that was developed by the National Institute of Standards and Technology (NIST) and the National Security Agency (NSA).

Web Distribution Point (WDP): A location on a server where offline address book (OAB) files are published for web distribution. A client can discover the URI of a WDP by using the Autodiscover Publishing and Lookup Protocol, as described in [MS-OXDSCLI].

MAY, SHOULD, MUST, SHOULD NOT, MUST NOT: These terms (in all caps) are used as defined in [RFC2119]. All statements of optional behavior use either MAY, SHOULD, or SHOULD NOT.
