Defines what content can exist in an XML document. DTDs are part of the W3C XML Specification 1.0.
DTD states what tags and attributes are used to describe content in an SGML document, where each tag is allowed, and which tags can appear within other tags.
A specific definition that accompanies a document and identifies how each markup (or tag) will be processed (also see markup, tag). Used in XML.
A Document Type Definition, or DTD, defines rules of structure that XML documents must follow. DTDs define mandatory and optional elements and attributes. They also define the order in which elements may appear. Many industries have standardized DTDs so that companies can exchange and process information regardless of computer platforms or software.
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.
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.
A description of a set of elements used to create a structured (or hierarchical) information. The Document Type Definition (DTD) specifies the syntax for each element and governs how and where elements can be used in a document.
a "template" document used to define the elements allowed in a particular type of an XML document
A description of all the valid elements contained in a document. Valid documents must conform precisely to the document type definition. Document Type Definitions (DTD) are the formalized methods for defining the exchange of data across applications.
a collection of ELEMENT, ATTLIST, ENTITY and NOTATION declarations that describes a class of valid documents
a file that states the syntax and format of an XML document
a set of markup declarations that provide a grammar for a class of documents
a specification that accompanies an XML document and identifies and processes the markup language that separate paragraphs, identify topic headings, etc
The formal specifications and definitions of the structural elements and markup to be used in encoding specific types of documents in SGML.
The predecessor of a schema definition (.dtd) file that specifies rules for elements, attributes, and relationships in an Extensible Markup Language (XML) document.
1) In SGML, a .dtd is a text file that describes the structure of a document and defines the framework for the elements (such as chapters and chapter headings, sections, and topics) that constitute a document. 2) In the SiteSearch system, a .dtd is a text file used by the sgmlconv utility program to map fields within an SGML source file to fields within a ASN.1/BER file.
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.
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 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.
a file that defines how applications interpreting a document should present the content. It is used in HTML, XML, and other Markup languages.
The definition of a document type in XML.
An SGML document type, e.g., HTML is a DTD.
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
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.
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.
(DTD) b . Describes the structure, content and semantics of XML documents. See: Schema
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.
Definition of a language built on eXtensible Markup Language (XML) or Standardised General Markup Language (SGML).
A specification that accompanies a SGML or XML document and identifies the content and relationships of markup elements in the document.
DTD) A file that identifies the elements and attributes that can be used to create the content of an XML document. It identifies where each element is allowed and which elements can appear within other elements.
"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
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 is a text file that specifies the meaning of each tag.
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.
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 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.
DTD) A group of statements that define element names and their attributes specifying the rules for combinations and sequences. It's the DTD that defines which elements can or cannot be inserted in the given context. DSSSL DSSSL stands for Document Style Semantics and Specification Language. It's an ISO standard (ISO/IEC 10179:1996). The DSSSL standard is internationally used as a language for documents style sheets pages for SGML.
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.
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.
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.
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.
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.
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 (DTD), defined slightly differently within the XML and SGML specifications, is one of several SGML and XML schema languages, and is also the term used to describe a document or portion thereof that is authored in the DTD language. A DTD is primarily used for the expression of a schema via 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. A DTD may also declare constructs that are not always required to establish document structure, but that may affect the interpretation of some documents.
