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. Available at http://library.csun.edu/mwoodley/dublincoreglossary.html

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. 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.

File that describes the structure of an XML document.

Document Type Definition. A DTD provides a list of the elements, attributes, comments, notes, and entities contained in the document, as well as their relationships to one another. DTDs and Markup Languages DTD glossary entry

(Document Type Definition) - A specific language for describing the structure of a class of structured documents, such as SGML of XML documents – now superseded by XML Schema. See SGML, and XML

Document Type Definition. Can accompany a document, essentially defining the rules of the document, such as which elements are present and the structural relationship between the elements. It defines what tags can go in your document, what tags can contain other tags, the number and sequence of the tags, the attributes your tags can have, and optionally, the values those attributes can have. DTDs help to validate the data when the receiving application does not have a built-in description of the incoming data. The DTD is declared within the document type declaration production of the XML file. With XML, however, DTDs are optional. See also schema.

See Document Type Definition.

Acronym for Document Type Definition or optionally Document Type Declaration, used in SGML and XML markup languages to specify the set of rules or grammar processed in a particular language. HTML versions each have their own DTD, for example.

A set of rules (a language) for defining the legal building blocks of a web document like HTML or XML

A type of file associated with SGML and XML documents that defines how the markup tags should be interpreted by the application presenting the document. The HTML specification that defines how Web pages should be displayed by Web browsers is one example of a DTD.

Document Type Definition. A DTD, or Document Type Definition, is an SGML or XML construct used to rigorously and unambiguously describe the structure and content of classes of documents in terms of SGML/XML instances (elements, attributes, entities, etc.). NOTE: "'DTD' is occasionally-but not in compliance with ISO 8879 terminology- used as an abbreviation for 'document type declaration'; it is also an SGML reserved word used in formal public identifiers to indicate that the identified entity is a document type declaration set, and is often used to identify such a set."

A Document Type Definition defines the syntax to use when using mark-up languages like HTML.

Document Type Definition: A predecessor to XML Schemas. Defines the structure of an XML document.

Document Type Definition. An electronic file linked to an SGML application that contains the attributes, elements, and entities that are assigned to the tags that mark up an SGML document. The DTD contains the rules for the structure of an SGML document. The DTD can exist separately from the document or be contained within it.

The early form of a schema definition file that specifies rules for XML document elements, attributes, and containment relationships.

Document Type Definition. A file in an XML document that defines how the application presenting the document should interpret the XML document.

Document Type Definition. A document which defines elements, attributes and other constraints so that XML documents of the specified type can be validated. An alternative to DTDs are XML Schema.

Document Type Definition (DTD) is a set of rules for an XML document that allows the XML authors to enforce the integrity of their XML documents.

document type definition. One of several ways in which the structure of an XML document can be described. BizTalk Server 2004 can open a schema described using a DTD, but converts it to XSD in the process.

Document Type Definition. A file that defines the elements and data structure contained in an XML document.

Document Type Definition. A formal definition of the data model (the elements and attributes allowed and their allowable content and nesting structure) for a class of documents. XML DTDs are written using SGML DTD syntax

see Document Type Description.

An "old-fashioned" means of specifying XML document structure. The sometimes cumbersome and non-XML-based syntax of DTD's is increasingly being replaced by XML Schema.

A DTD is the formal definition of the elements, structures, and rules for marking up a given type of SGML document. You can store a DTD at the beginning of the document or externally in a separate file.

Acronym for Document Type Definition. A DTD definition states which elements can be nested within others, and acts as a rule-set, defining the names and contents of all elements that are allowed within a document, their order and quantity etc.

A way to define the legal elements and other building blocks of an XML document.

Document type definition. A set of rules for document construction that lies at the hearts of all SGML development and all valid XML document construction. Processing applications and authoring tools rely on DTDs to inform them of the parts required by a particular document type. A document with a DTD may be validated against the definition.

Document Type Definition. A document that describes the structure of a Web page written in XML.

Document Type Definition. XML 1.0 DTDs are inherited from SGML, in which rules were included that allow the customization of the markup itself and played a very central role. Because of the syntactical rules included in their DTDs, SGML applications need a DTD to read an SGML document. One of the simplifications of XML is to state that a XML parser should be able to read a document without needing a DTD. DTDs have therefore been simplified from their SGML ancestors and remain the first incarnation of what is today called an XML Schema Language.

Document Type Definition. This is a text file which contains all SGML object declarations for a specific document type.

(Document Type Definition) ---- rules for EBNF transformational grammar of tex

A formal specification of the structural elements and markup definitions to be used in encoding certain types of documents in SGML (which see). Instances of DTDs include EAD (which see), HTML (which see) and TEI (which see).

Document Type Definition Documents are regarded as having types, just as other objects processed by computers do. The type of a document is defined by its constituent parts and structure. A DTD defines the structure of an SGML (Standard Generalized Markup Language) document.

Document Type Definition file that specifies how elements inside an XML document should relate to each other. It provides "grammar" rules for an XML document and each of its elements. DLESE's metadata records are XML documents.

document type definition. In common usage, DTD has come to stand for the formal constructs that appear in a declaration subset. Officially, the document type definition also includes informal guidelines or conventions that makeup an SGML application.

Document Type Definition. A specific definition that accompanies a document and identifies how each markup (or tag) will be processed (also see markup, tag). Used in XML.

Document Type Definition; an SGML description of a document markup language (such as HTML).

Document type Definition - see appendix 3

Document Type Definition. An XML Schema, defining grammar or structure, and nesting of content.

Short for Document Type Definition. A DTD states what tags and attributes are used to describe content in an XML or HTML document, where each tag is allowed, and which tags can appear within other tags. For example, in a DTD one could say that LIST tags can contain ITEM tags, but ITEM tags cannot contain LIST tags. In some editors, when authors are inputting information, they can place tags only where the DTD allows. This ensures that all the documentation is formatted the same way. Applications will use a document's DTD to properly read and display a document's contents. Changes in the format of the document can be easily made by modifying the DTD.

Document Type Definition. A DTD defines the legal building blocks of an XML document. It defines the document structure with a list of legal elements.

Document Type Definition, for the definition of XML based languages. An newer alternative is the schema.

(XML) Document Type Definition

A document type definition (DTD) is simply a definition of a certain type of XML document and provides a set of rules for the XML document with which it is associated.

Document Type Definition. a file that defines how applications interpreting a document should present the content. It is used in HTML, XML, and other Markup languages.

A mark-up specification for a class of documents, defined within the SGML framework.

Document type definition. An SGML document, which formally defines the relationship between elements, what attributes each entity has and which values these attributes may take. Used by validators and checkers to make sure your documents adhere to the standard.

Document Type Definition) A specification for a markup language such as HTML.

Document Type Definition, a specification of an XML grammar. A DTD allows parsers to validate XML.

XML lets you store arbitrary data in an organized manner, and it lets you design how to lay it out. Sometimes, however, you may wish to explain exactly how you laid things out. You can do so with a DTD (document type definition), which further lets your XML parser check that the data you are reading is a well-formed XML document and conforms to your specified layout. A DTD is a contract that specifies an XML document's layout. However, DTD suffers from not being XML: its roots lie in SGML (Standard Generalized Markup Language), forcing you to learn another language. Moreover, DTDs do not work well with namespaces, and they are not particularly good at nailing down exactly what you can put where. A general push is on to replace DTDs with XML Schema.

Document Type Definition. A DTD is used to define the legal building blocks of an XML document. A DTD can be declared within an XML document or referenced externally.

Document Type Definition. a markup declaration used by SGML and XML that contains the formal specifications, or grammar, of an SGML or XML document. One use of the DTD is to run a validation process over an XML file, which indicates if it matches the DTD, or if not, provides a listing of each line at which the file fails some part of the required structure.

Document Type Definition. In SGML and XML, a document that gives the rules for tags and their attributes.

document type declaration. A set of declarations that defines the names of the elements and their attributes, and that specifies rules for their combination or sequence.

Document type definition. Defines the elements and structure of an Extensible Markup Language (XML) document or data set.

"Schema language for SGML, and XML."

From Glossary of "Weaving the Web" ( 1999-07-23) In the SGML world, a DTD is a metadocument containing information about how a given set of SGML tags can be used. In the XML world this role will be taken over by a schema. Sometimes, but arguably, "document type definition." See also schema.

Abbreviation of document type definition: a description of the structure of types of document in SGML and XML; it defines how the constituent text and mark-up –(tags) should be parsed by an application which processes such a document. However, e-GIF mandates the use of XML schema rather than DTD for this purpose.

SGML Document Definition File

Document Type Definition. A DTD is a formal specification of the structure of a class of XML documents. DTDs (or XML Schemas which serve essentially the same purpose) are used to validate the correctness and completeness of XML document instances. By definition all OAI-PMH responses must be valid XML document instances.

Document Type Definition. A standard definition that specifies which elements and attributes might be present in other elements and attributes and that specifies any constraints on their ordering, frequency, and content.

(Document Type Definition)—A document defining the format of the contents present between the tags in an XML or SGML document, and the way they should be interpreted by the application reading the XML or SGML document.
