Document Type Definition: a language for describing XML document syntax.

DTD defines what level of valid HTML code appears in a file. On the World Wide Web, a DTD sequence for a valid XHTML Web page looks like this:!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd"

Data Type Description, XML-based (written in XML) document descriptions against which XML documents are validated.DTDs have been defined for: Automotive (J2008) Aviation (ATA 100, AECMA) Publishing (ISO 12083, Majour) Software Documentation (DocBook) HTML is a DTD

The rules that define the tags that can be used in an XML file and their valid values.

a language for describing XML file layouts

A DTD outlines the rules of a particular document structure. It lists the elements, attributes, and entities in a document and it defines the relationships between the different elements and attributes.

This is a text document used to define the structure and tags for an XML document so that it can be validated. The DTD was originally developed for use with SGML (on which XML is based).

ocument ype efinition is a set of rules that defines a particular type of file. Every subset of HTML (HTML 2.0, HTML 3.0, Netscape Extensions) has an associated DTD.

A document type declaration that specifies that possible structure of XML or SGML documents.

The rules governing the data structure of a specific XML markup language.

The definition of a document type in SGML or XML, consisting of a set of mark-up tags and their interpretation.

A set of rules and relationships for structuring data in a SGML-coded file to insure consistency and therefore reusability.

Document Type Definition. A set of rules that define the allowable structure of an XML document. DTDs are text files that derive their format from SGML and can either be included in an XML document by using the DOCTYPE element or by using an external file through a DOCTYPE reference.

Document Type Definition. The predecessor of a schema definition (.dtd) file that specifies rules for elements, attributes, and relationships in an Extensible Markup Language (XML) document.

Document Type Definition - defines how markup tags should be displayed by an application.

Document Type Definition. In SGML or XML, a DTD is a formal definition of the elements and the relationship among the data elements (the structure) for a particular type of document.

Stands for "Document Type Definition." A DTD defines the tags and attributes ...

Document Type Definition, which is a set of instructions for a document type, ensuring that an XML document uses uniform grammar and structure. A DTD can be either internal or external to the XML document or held in an external repository. (See also Schema)

Document Type Definition, used in conjunction with SGML coding. DTDs record tagging conventions for chapters, paragraphs, etc. A program will use the DTD to verify that SGML coding is syntactically correct.

A Document Type Description (DTD) defines the structure and legal elements of an XML document. An alternative to DTDs is XML Schema.

This abbreviation could be confusing as it is sometimes incorrectly used for two different but related phrases: DTD and DTDecl. Document Type Definition (DTD) The Document Type Definition defines a particular application of SGML, such as HTML or XML. It states which element, attribute and entity types and other components are permitted in the particular document. These statements are written as markup declarations and specify among other things inheritence (eg that element A can or cannot be a child of element B). In XML only documents with DTDs are valid documents. Example Here is an HTML 4.0 example of the DTD fragment for a paragraph (i.e. the definition of the HTML 4 paragraph). It states that a paragraph is an inline element. !ELEMENT P - O (%inline;)* -- paragraph -- NOTE: the HTML DTDs do not comply 100% to the syntax of SGML DTDs (such as the O's above - for Optional). This has been rectified in XHTML.

Document Type Definition. A specific definition that follows the rules of the Standard Generalized Mark-up Language (SGML) accompanying a document and identifies the mark-up that separate paragraphs, identify topic headings, etc. and how each should be processed.

Document Type Definition. One way of describing an XML format.

Document Type Definition. A specification that accompanies a SGML or XML document and identifies the content and relationships of markup elements in the document.

Document Type Definition. Previously did the job of Schemas. No longer widely used.

Document Type Definition. A set of rules that defines the allowable structure of an XML document. DTDs are text files that derive their format from SGML and are either embedded within an XML document or referenced by an XML document.

Document Type Declaration or Document Type Definition, depending on context.

Document Type Definition -- this is a specific markup language, written using SGML.

Document Type Definition. DTD files contain information that defines XML tag sets, usage, and attributes. A DTD defines a "data dictionary" or vocabulary for specific XML elements, and is used to validate the markup. A valid XML document is one that refers to a DTD.

Document Type Definition. Defines what content can exist in an XML document. DTDs are part of the W3C XML Specification 1.0.

Document Type Definition. The rules for the correct structure of data expressed in XML. For example, the I3N DTD dictates that a Project description must have at least one Contact, and the Contact consists of name, date, address, phone, fax, email. By providing a DTD with an XML document, any location that has a DTD "reader" (or "SGML compiler") will be able to process the document and display or print it as intended.

Document Type Definition. Schema used to constrain XML documents. DTDs are in widespread use, but the newer XML schema is the preferred schema approach.

Document Type Definition, which declares a set of XML element names and how they can be used in a document.

Document Type Definition. "In SGML or XML, a formal description of the components of a specific document or class of documents. DTDs provide a formal grammar used for machine processing (parsing) of documents expressed in SGML or XML. A DTD description includes: The containers or elements that make up the document; e.g., paragraphs, headings, list items, figures, tables, etc. The logical structure of the document; e.g., chapters containing sections, etc. Additional information associated with elements (known as attributes); e.g., identifiers, date stamps, etc. " Dublin Core Metadata Glossary, Final Draft, Feb. 24, 2001, Online.

Document Type Definition A common way of defining the structure, elements, and attributes that are available for use in a SGML or XML document that complies to the DTD. For example, the Text Encoding Initiative (TEI) DTD governs the structure, elements, and attributes of a TEI document.

(Document Type Definition) A file that contains declarations of elements, attributes, and entities and rules for how they are to be combined in a document.

DTD (XML Document Type Definition) defines elements and data structures of XML documents.

Document Type Definition. An XML document used to validate other XML documents. Oracle Syndication Server uses an ICE agent layered on Dynamic Services to take a content syndication or a content subscription request in the form of an XML document, which is validated against a predetermined ICE protocol Document Type Definition (DTD).

Document Type Definition (a filetype associated with XML)

document type definition. a "template" document used to define the elements allowed in a particular type of an XML document

A Document Type Definition (DTD for short) is a set of declarations that conform to a particular markup syntax and that describe a class, or "type", of SGML or XML documents, in terms of constraints on the structure of those documents.

Document Type Definition - specifies a set of elements, their relationships and the tag set to mark the document. A good introduction to SGML concepts can be found at pineapplesoft.com. In mozilla, DTD is also a class used by the parser inheriting from nsIDTD.

A Document Type Definition. It specifies the syntax used in documents. Examples of well-known DTDs include: HTML, XHTML, DocBook, TEI, MathML, MusicML, etc. SGML and XML give a framework for writing DTDs.

DTD or Document Type Definition is a description of the structure and properties of a class of XML files.

(Document Type Definition) -- The document map for tailored SGML applications. The DTD defines the structure and elements of a particular document style. For example, a book would have one DTD while an article would have a different DTD, since the sections and content of these two types of publications differ. It is a flexible document map that one can tailor for one's own applications.

A definition of the grammar for a class of XML documents. It is used in validation of documents.

Document Type Definition. Markup declarations that provide a grammar for a class of documents.

Document Type Definition. (#NOK) The definition states which elements can be nested within others. A DTD defines that the names and contents of all elements that are permissible in a certain document, how often an element may appear, the order in which the elements must appear, whether the start or end tag may be omitted, the contents of all elements, that is, the names of the other generic identifiers that are allowed to appear inside them, the attributes and their default values and the names of the reference symbols that may be used.

document type declaration. In XML, every valid document has a DTD that describes the elements available in that document type. A DTD can be embedded in the XML document or referenced by it.

Document Type Definition. The DTD is written using SGML and describes the sort of document to be used; for example, a manual or an article for a newspaper. The DTD contains declarations, each of which defines a construct to be used in a style of document. HTML is an SGML DTD.

Document Type Definition. Document type definition is a text file that specifies the meaning of each tag.

schema specification method for XML documents. A DTD is a collection of XML markup declarations that define the structure, elements and attributes that can be used in a document that complies with that DTD. By consulting the DTD a parser can work with the tags from the markup language that document uses. DocBook is an example of a DTD often used with technical documentation to enable sharing and reuse.

A DTD (Document Type Definition) 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.

A DTD is a Document Type Definition, which was the original format used in XML to define the structure of documents or data. DTDs are not generally used to document Jabber XML formats; instead, XML Schemas are used.

document type definition. Rules that apply SGML to the markup of documents of a particular type, including a set of element and entity declarations. [SGML

document type definition. a formal, machine-readable expression of the XML structure and syntax rules to which a document instance of a specific document type must conform; the schema type used in XML 1.0 to validate conformance of a document instance to its declared document type. The same markup model may be expressed by a variety of DTDs.

Document Type Definition. This is a formal definition of a discrete set of XML tags usually targeted at a particular type of application. For example, the Document Type Definition for the Digital Talking Book would define tags for things one finds in a book, e.g., chapter, paragraph, footnote, jacket, etc.

A DTD, or document type definition, is a collection of XML markup declarations that, as a collection, defines the legal structure, elements, and attributes that are available for use in a document that complies to the DTD.

Document Type Definition. A language used to describe document structures in SGML. Before XML Schema were standardised, DTDs were also widely used to specify the structure of XML documents.

Document Type Definition. The specification that defines the structure of the markup elements in an HTML document and determines how to place elements inside the document.

Document Type Definitions

Document Type Definition. Formal descriptions of a language, typically written in SGML. Used with the HTML DOCTYPE tag to tell validators and other software which version of HTML is used in the document. Often abbreviated DTD.
