HTML 2.0 Specification (Internet Draft)

7. Glossary

attribute

A syntactical component of an HTML element which is often used to specify a characteristic quality of an element, other than type or content.

document type definition (DTD)

A DTD is a collection of declarations (entity, element, attribute, link, map, etc.) in SGML syntax that defines the components and structures available for a class (type) of documents.

element

A component of the hierarchical structure defined by the document type definition; it is identified in a document instance by descriptive markup, usually a start-tag and an end-tag.

HTML

HyperText Markup Language.

HTML user agent

Any tool used with HTML documents.

HTML document

A collection of information represented as a sequence of characters. An HTML document consists of data characters and markup. In particular, the markup describes a structure conforming to the HTML document type definition.

HTTP

A generic stateless object-oriented protocol, which may be used for many similar tasks by extending the commands, or "methods", used. For example, you might use HTTP for name servers and distributed object-oriented systems, With HTTP, the negotiation of data representation allows systems to be built independent of the development of new representations.

(document) instance

The document itself including the actual content with the actual markup. Can be a single document or part of a document instance set that follows the DTD.

markup

Text added to the data of a document to convey information about it. There are four different kinds of markup: descriptive markup (tags), references, markup declarations, and processing instructions.

Multipurpose Internet Mail Extensions (MIME)

An extension to Internet email which provides the ability to transfer non-textual data, such as graphics, audio and fax. It is defined in RFC 1341.

representation

The encoding of information for interchange. For example, HTML is a representation of hypertext.

rendering

Formatting and presenting information.

SGML

Standard Generalized Markup Language is a data encoding that allows the information in documents to be shared -- either by other document publishing systems or by applications for electronic delivery, configuration management, database management, inventory control, etc. Defined in ISO 8879:1986 Information Processing Text and Office Systems; Standard Generalized Markup Language (SGML).

SGMLS

An SGML parser by James Clark, jjc@jclark.com, derived from the ARCSGML parser materials which were written by Charles F. Goldfarb. The source is available at ftp.ifi.uio.no/pub/SGML/SGMLS.

tag

Descriptive markup. There are two kinds of tags; start-tags and end-tags.

URI

Universal Resource Identifiers (URIs) is the name for a generic WWW identifier. The URI specification simply defines the syntax for encoding arbitrary naming or addressing schemes, and has a list of such schemes. See also: http://info.cern.ch/hypertext/WWW/Addressing/Addressing.html

WWW

A hypertext-based, distributed information system created by researchers at CERN in Switzerland. Users may create, edit or browse hypertext documents. The clients and servers are freely available.See also: http://info.cern.ch/hypertext/WWW/TheProject.html
