Terminology

On this web site we are using specific terms, some of which might be unclear to the non-technical reader. Sorry, but there is no way around calling things by their real precise name - and we believe that there is nothing wrong about this as long as we explain what these terms really mean.

This is why we explain these terms on this page.

A|B|C|D|E|F|G|H|I|J|K|L|M|N|O|P|Q|R|S|T|U|V|W|X|Y|Z

abstract

A short summary of the essential content of a book, article, speech, report, dissertation, or other work of nonfiction which gives the main points in the same order as the original work, without claiming or possessing independent literary merit.

Align Left

(ragged right) Pertaining to copy which is aligned on the left margin. 2. (quad left) A code which directs preceding copy to be set flush against the left margin.

Align Right

(ragged left) Pertaining to copy which is aligned on right margin. 2. (quad right) A code which directs preceding copy to be set flush against the right margin.

Alignment

The positioning of text within the page margins. Alignment can be flush left, flush right, justified or centred. Flush left and flush right are sometimes referred to as left justified and right justified.

Alternate Characters

Multiple versions of different characters, usually in display type faces, to apply a greater variety or personality to the copy. This often refers to swash characters, which usually over- or under-hang adjacent characters with curve-like flourishes.

Ampersand

A symbol (&) meaning and. The ampersand was originally a ligature for et (the Latin word for and), expressed as et per se, which gradually evolved to its present form.

ancestor genealogy

In object-oriented software development creating classes in a genealogy (inheritance) tree has been common practice for almost two decades. Children objects inherit attributes (descriptive data) and behavior (code) from their mother and grandmothers over several inheritance levels. This is a key internal feature of every Java or Smalltalk and many C++ applications. It's just state-of-the-art! This important feature been bot yet been used for application data, although this would substantially ease the creation and maintenance of complex data structures as used in a publishing system. And it would show the entire system much better and clearer arranged.

ElePub and EleStore are the first software products offering full data inheritance via a multi-level inheritance tree for your application data.

Annotation

Boolean

A field of mathematical logic developed in the mid-19th century by the English mathematician George Boole which allows a database searcher to combine concepts in a keywords search using three commands, also known as "operators": The OR command is used to expand or broaden search results by including synonyms and related terms. Search statement: violence or conflict or aggression. The AND command is used to narrow search results. Each time another concept is added using "and" the search becomes more specific. In some online catalogs and electronic databases, the "and" command is implicit (no need to type it in a keywords search). Search statement: violence and television The NOT command is used to exclude unwanted records from search results.

Bullet

A common pi character usually used to draw attention to listed items.

Byte

A unit of digital information consisting of 8 bits. Each ASCII text character is referenced by one byte of data. File sizes are typically measured in bytes, kilobytes (thousand bytes) or megabytes (million bytes).

CDF CDF Catalog Data Format is a special intelligent data format used by our electronic product catalog EleCat to store, distribute and visualize pages of any kind, primarily product catalog pages, with many different types of data and links. CDF is an autonomous data format first introduces in January 1993 (and therefore older than PDF).

CDF is fully object-oriented and the technical basis of EleCat. It can store any data of data not matter how complex. EleCat's features many specia features and benefits could not be achieved with any other existing data format. One of the greatest specialities of CDF is the update system. CDF is capable of logically adding any number of changes, updates or additions to a CDF file, which only logically overwrites older data, which can still be restored if needed. It supports versioning and version history!

CGI script

Short for Common Gateway Interface script. - An external application that is executed by an HTTP server machine in response to a request by a client such as a Web browser. The most commonly used language for CGI scripts is Perl, because it is a small but robust language. CGI scripts can also be written in C, C++ and Visual Basic.

EleCat EleCat is the eletronic product catalog software bringing product catalogs onto any PC and onto the Internet. EleCat is especially capable of making printed paper catalogs easily available for electronic use. All EleCat vesions have a database and components of pages are linked to records in the database. Most versions of EleCat also offer an order entry system and a permanent update system over the Internet. EleCat is often distributed on CD-ROM together with very large catalog files in CDF and databases but it can, of course, also be distributed over the Internet. Several versions of EleCat are also capable of converting product catalogs to HTML for use in an Internet browser. For details see www.elecat.com.

FTP is a special way to login to another Internet site for the purposes of retrieving and/or sending files. There are many Internet sites that have established publicly accessible repositories of material that can be obtained using FTP, by logging in using the account name anonymous, thus these sites are called anonymous ftp servers

full-text searching

The capability of searching every word in set of documents or database entries, as opposed to searching only in the title and/or abstract, or in the keywords, headings, or descriptors assigned to each item.

full-text

Refers to database or other electronic resource which provides the entire text of a significant proportion of the works it contains, for example, a periodical database containing the complete text of a significant proportion of the articles indexed, in addition to the citation and abstract of each work.

GIF

(Graphic Interchange Format) GIF (pronounced "gift") is a graphics format that can be displayed on almost all web browsers. It is a common compression format used for transferring graphics files between different computers. Most of the "pictures" you see online are GIF files. They display in 256 colors and have built-in compression. GIF images are the most common form of banner creative.

HTML

HyperText Markup Language is a coding language used to make hypertext documents for use on the Web. HTML resembles old-fashioned typesetting code, where a block of text is surrounded by codes that indicate how it should appear. HTML allows text to be "linked" to another file on the Internet

HTTP

HyperText Transfer Protocol, the format of the World Wide Web. When a browser sees "HTTP" at the beginning of an address, it knows that it is viewing a WWW page.

HTTPS

Another protocol for transmitting data securely over the World Wide Web is Secure HTTP (S-HTTP). Whereas SSL creates a secure connection between a client and a server, over which any amount of data can be sent securely, S-HTTP is designed to transmit individual messages securely. SSL and S-HTTP, therefore, can be seen as complementary rather than competing technologies. Both protocols have been approved by the Internet Engineering Task Force (IETF) as a standard.

Hyperlink

This is the clickable link in text or graphics on a web page that takes you to another place on the same page, another page or a whole other site. It is the single most powerful and important function of online communications. Hyperlinks are revolutionizing the way the world gets its information. The following hyperlinks make New York, London, Tokyo, Sydney or Los Angeles only one click and seconds away – all for exactly the same price.

Hyphenation

The practice of dividing words by leaving part of the word at the end of one line and continuing it on to the next, with a hyphen at the end of the first part of the word. Many words have their own rules for hyphenation that are not consistent with the general rules of the language, and must be hyphenated according to an exception word dictionary.

Hyphenation & Justification (H&J)

The practice of adjusting blocks of type so that they are both left and right aligned, with hyphenation occurring as appropriate, word spaces adjusted for good fit, and overall appearance satisfactory. Although each are in fact separate processes, they are often used together so that the hyphenation may enhance the results of justification.

Image area

The area of a page inside the margins in which you put the text and graphics. (Objects can extend outside this area.)

Image Compression

File size reduction. Lossless compression enables images to be decompressed without degradation in image quality. Lossy compression sacrifices varying degrees of image detail for greater compression ratios – usually used in Multimedia applications.

Image Editor

A program that can be used to make changes in computer graphics. The program can be used to crop enhance paint and filter scanned images. Adobe Photoshop is an example of an image editing tool. Some page layout programs such as Quark and Pagemaker allow image editing after the image has been imported.

Image Format

A format in which an image can be stored and used. Some formats, such as TIFF and PICT, can be imported into many different programs and transferred between different platforms. GIF and JPEG are formats used for images on HTML pages. There are image conversion tools in some programs (for example, Photoshop), which make it possible to change from one format to another.

Imagesetter

A machine that produces line images, half tone images, and typographic composition on paper or on film.

Impression

A single image transferred by a printing device to one side of a sheet of paper.

Indent

The positioning of text so that a margin of the line or lines appears a fixed distance from the left and/or right margin.

Inheritance

In software development this is the ability (of a programming language) to build new abstractions and objects out of existing ones as an extension or specialization of another class or object. Most object-oriented languages support class-based inheritance, while others such JavaScript only support object-based inheritance. In ElePub and EleStore inheritance is also available for user application data.

Instances A child object inheriting from a mother object or, in programming, from a class is called an instance.

Intranet

An intranet is a computer network used within one company or organization. Intranets are private networks, usually maintained by corporations for internal communications, which use internet -- usually web -- protocols, software and servers. They are relatively cheap, fast, and reliable networking and information warehouse systems that link offices around the world. They make it is easy for corporate users to communicate with one another, and to access the information resources of the internet.

IP address

Internet Protocal address. Every system connected to the Internet has a unique IP address, which consists of a number in the format A.B.C.D where each of the four sections is a decimal number from 0 to 255. Most people use Domain Names instead and the resolution between Domain Names and IP addresses is handled by the network and the Domain Name Servers. With virtual hosting, a single machine can act like multiple machines (with multiple domain names and IP addresses).

ISDN

(Integrated Digital Services Network) ISDN lines are high-speed dial-up connections to the internet. It is a lot of commotion for a connection roughly four times faster -- 128,000 bits per second -- than a normal phone line.

Italic

Pertaining to type that is a `slanted' version of a type face. It is used primarily for emphasis within text. Most typesetters can produce pseudo-italic (oblique) versions of fonts electronically by skewing the digitised characters.

JPEG

Joint Photographic Experts Group. A format for storing high-quality color and grayscale photographs in bitmap form; also the group that developed the format. JPEG provides lossy compression by segmenting the picture into small blocks which are divided to get the desired ratio; the process is reversed to decompress the image. JPEG uses the JPEG File Interchange Format, or JFIF.

Justification

The process of composing and adjusting line of type by adding space between the words and characters so that the lines are aligned on left and right margins.

Justification Range

The space at the end of a line of type within which the computer will determine the acceptable line breaks before actual justification.

Kern

The process of subtracting space between two characters so that they appear closer together. This is usually done to improve the aesthetic appearance of most words that are set in all capitals especially in large display and headline text lines. 2.The part of a letter which actually overhangs the body of the letter itself, such as the curl at the top of the lower case f in a serif face.

Kerning

Reducing the spacing between certain pairs of letters in a proportional-pitch type to improve the appearance of the line of type. For example, A and V look better next to each other if they are moved closer together than, for example, A and B.

Kerning Pairs

In a computerised typesetting system, certain pairs of characters may be defined with specific kerning values. When type is set, kerning is automatically done between those specified pairs.

LAN

Local Area Network. This network connects computers or workstations allowing users to access the same information simultaneously.

Leading

Pronounced ledding. The distance of the base line of a line of type from the base line of the line below it, measured in points.

Legacy

OF or pertaining to documents, data or hardware that existed prior to a certain time. The designation refers particularly to a change in process or technique that requires translating old data files to a new system.

Letterspacing

The addition of thin spaces between the letters in order to achieve the desired appearance of text, and increase legibility.

Ligature

Two or more letters tied together into a single letter. They are designed to improve the appearance of certain character combinations. The standard ligatures are: ff, fi, fl, ffi, and ffl.

line frequency

The number of lines counted vertically used by a printer to create an image.

Line Length

The width of a line of type, or column, or page (usually in picas and points) as set by typographic commands. The actual type on the line may not fill the entire line length. Also known as measure.

Logo

An emblem, short for logotype. Can be either a unique arrangement of letters, a symbol, or a combination of both.

lpi

Lines Per Inch. A measurement of the resolution of a halftone screen, or of the number of lines a printer prints on a page in each vertical inch.

LZW

A patented lossless data compression scheme that reduces image file size if the data can be compressed without degradation. (common option for .TIF bitmaps)

Mail Merge

A way of using a computer to print customized form letters. Name and address information for each letter to be printed will be inserted at designated merge points.

Manuscript

The original material from which type will be set. May be handwritten, typewritten or on a floppy disk.

Margin

The unprinted space on either side of a block of text. Usually refers to the space between text and the edge of the page, as opposed to space between columns. 2.The position of the leftmost edge of the type image on the page.

Mark up

The written specifications indicating the particulars of typography and measurement, used as guidelines or instructions for implementation of the work.

MB

Megabyte. One million bytes (1,048,576 bytes).

Metadata

Data about data. For example, the title, subject, author, and size of a file constitute metadata about the file.

Middleware

Software that sits between two or more types of software and translates information between them. Middleware can cover a broad spectrum of software and generally sits between an application and an operating system, a network operating system, or a database management system.

Monospaced font

A font in which all characters have uniform widths.

Mother objects A mother object in ElePub and EleStore is a rather generic data object (collection of data values describing an abstract application data item such as an article or a frame on a page). Mother objects are not directly used, i.e. a mother article is never offered or sold nor placed on a page but it serves as a template for "real" articles inheriting from this mother object. The children automatically receive not only the template (of features and attributes) from its mother but also the values stored inside the mother. Any of these values can be overwritten by the child's own values stored inside the child object. Mother objects can be grouped in a multi-level tree of mother, grandmothers etc. Such as tree organization greatly eases the maintenance of large databases and it reflects the natural dependencies of such data items.

Nested Indent

An indent whose indentation is measured from the margin of the last indent, rather than the absolute margin.

object-oriented

Being object-oriented or object orientedness is a "notion", which can be associated with systems and especially with programming languages. To be object-oriented a programming language must at least:

  • Provide some form of classes and objects.
  • Support inheritance, the ability to build new abstractions and objects out of existing ones.
  • Run-time polymorphism, the ability to bind code components dynamically at run-time (as opposed to static or compile-time binding typically used in most programming languages).

This last criteria is the reason why C can never be object-oriented, and why C++ can is definetely not a pure o-o language. C++ can only be called object-oriented with severe limitations (one can theoretically develop in o-o style in C++, but hardly anybody ever does so because it is very badly supported).
Typical o-o languages today are Java and Smalltalk, the oldest, most mature and purest o-o language in wide use today (not mentioning the many o-o languages of purely academic importance). Basically, Java is much of Smalltalk, in C++ syntax, but with substantial limitations in the features and especially in the development environment.

object repository A storage for obejcts so that they can be (re-) used by other objects. In the case of ElePub a database containing mother objects used as templates for creating "real" objects on pages such as tables, frames or containers holding frames, tables or other containers.

Oblique

The characteristic of a type face which has been skewed from a digitised character, thus looking like an italic typeface. The angle of skew is either 12° or 15°.

Old Style Figures

A set of numerals which do not line up along the base line of type. Also known as non-aligning figures.

On Demand

On Demand is a method of document creation which streamlines production and distribution through the use of technology. The goal is to decrease waste because of over-ordering or out of date content and a more useful, relevant document resulting from the ability to keep content current and dynamic.

ONLINE

Accessing a remote computer via a terminal.

Open Architecture -

Any computer, peripheral, or application design that has published specifications. A published specification lets third parties develop add-on hardware or modules for a computer or copmputer application.

Optical Character Recognition (OCR)

The process in which an electronic device examines printed characters on paper and determines their shapes by detecting patterns of dark and light. Once the scanner or reader has determined the shapes, character recognition methods-pattern matching with stored sets of characters-are used to translate the shapes into computer text.

Orphan

An element of type (such as a word or a line) which leads into a larger block of type, but which has been left by itself at the end of a page or column. For instance, the first line of a paragraph, or a section head. Sometimes erroneously called a widow.

Page Makeup
