1.1 Glossary

Office

This document uses the following terms:

ActiveX control: A reusable software control, such as a check box or button, that uses ActiveX technology and provides options to users or runs macros or scripts that automate a task. See also ActiveX object.

add-in: Supplemental functionality that is provided by an external application or macro to extend the capabilities of an application.

atom record: A record that contains presentation data. Analogous to a file system, atom records are similar to files that contain data and container records are similar to directories that provide structure and hierarchy for atom records.

Audio Interchange File Format (AIFF): A sound file format that was originally used on Macintosh and Silicon Graphics (SGI) computers. AIFF stores waveform files in an 8-bit monaural format. See also waveform (WAV).

Audio Video Interleaved (AVI): A multimedia file format for sound and video that uses the Microsoft Resource Interchange File Format (RIFF).

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].

big-endian: Multiple-byte values that are byte-ordered with the most significant byte stored in the memory location with the lowest address.

bookmark: An entity that is used in a document to denote the beginning and ending character positions of specific text in the document, and optionally, metadata about that text or its relationship to other referenced parts of the document.

Boolean: An operation or expression that can be evaluated only as either true or false.

build: An animation effect that is applied to content on a presentation slide. The complete animation for a given piece of content is specified as a sequence of builds, where each build causes parts of the content to appear, disappear, move, or be emphasized in some manner.

build identifier: An integer that identifies a build.

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.

color scheme: A table of color values that enables colors to be referenced by an index value in the table instead of a color value. See also color palette.

color space: A system that describes color numerically by mapping color components to a multidimensional coordinate system. The number of dimensions is typically two, three, or four. For example, if colors are expressed as a combination of the three components red, green, and blue, a three-dimensional space can describe all possible colors. Grayscale colors can be mapped to a two-dimensional color space. If transparency is considered a component, four dimensions are appropriate. Also referred to as color model.

computer name: The DNS or NetBIOS name.

container record: A record that defines the structure and hierarchy of atom records and other container records.

cyclic redundancy check (CRC): An algorithm used to produce a checksum (a small, fixed number of bits) against a block of data, such as a packet of network traffic or a block of a computer file. The CRC is a broad class of functions used to detect errors after transmission or storage. A CRC is designed to catch random errors, as opposed to intentional errors. If errors might be introduced by a motivated and intelligent adversary, a cryptographic hash function should be used instead.

encrypted document: A document that was converted from plaintext into cipher text to disguise the content of the document when it is stored or sent.

envelope: A container that stores the information that is used to send a document, workbook, or presentation in an email message. The information includes the intended recipients, the subject of the email message, and any attachments to be included.

external object: An object such as a movie file, audio file, OLE object, or hyperlink that can be associated with a presentation or document.

floating-point number: A number that is represented by a mantissa and an exponent according to a given base. The mantissa is typically a value between "0" and "1". To find the value of a floating-point number, the base is raised to the power of the exponent, and the mantissa is multiplied by the result.

footer: One or more lines of text in the bottom margin area of a page in a document or a slide in a presentation. A footer typically contains elements such as the page number and the name of the file.

grid unit: A unit of linear measurement that is equal to 1/1024 master unit or 1/589824 inch.

guide: A vertical or a horizontal line that can be set as part of the user interface to position and align content on a slide.

handout master slide: A slide that defines layout and positioning information for handout pages, which are pages that are optimized for printing a presentation.

handout slide: A slide that is taken from a presentation and then printed and distributed to the audience of the presentation. Users can select the number of slides to be printed on each page in a handout.

header: A line, or lines, of content in the top margin area of a page in a document or a slide in a presentation. A header typically contains elements such as the title of the chapter, the title of the document, a page number, or the name of the author.

hue-saturation-luminance (HSL): A color model that defines a color by using three dimensions: hue, the color itself; saturation, the purity of the color; and luminance, the amount of light that is either reflected or absorbed by the color. See also color scheme and color space.

hyperlink: A relationship between two anchors, as described in [RFC1866].

kiosk mode: A display mode in which a single window expands to fill the whole screen. In kiosk mode, the toolbar and menu bar are not displayed, and the desktop is inaccessible.

little-endian: Multiple-byte values that are byte-ordered with the least significant byte stored in the memory location with the lowest address.

macro: A set of instructions that are recorded or written, and then typically saved to a file. When a macro is run, all of the instructions are performed automatically.

main master slide: A slide that defines the formatting and content that can be used by presentation slides. If a slide uses formatting and content from a main master slide, it is referred to as following a main master slide.

master unit: A unit of linear measurement that is equal to 1/576 inch.

Media Control Interface (MCI): A part of the Windows API that enables an application to control multimedia devices. The term is also used to generically describe any media object that can be played through the interface.

metafile: A file that stores an image as graphical objects, such as lines, circles, and polygons, instead of pixels. A metafile preserves an image more accurately than pixels when an image is resized.

Musical Instrument Digital Interface (MIDI): A specification of the MIDI Manufacturers Association (MMA). The specification for Musical Instrument Digital Interface (MIDI) defines a protocol for describing music data, such as note on and note off messages; a file format for storing music data, called Standard MIDI; and a standard hardware interface.

time node: A record or parent node that stores the information that is necessary to cause a time- or action-based effect to occur. Each time node has a corresponding object to which an effect is applied. It can be used randomly, simultaneously, or sequentially, and it can be used to specify certain time-based effects between objects that are being animated. Effects include visual and media behaviors.
