In general, a namespace uniquely identifies a set of names so that there is no ambiguity when objects having different origins but the same names are mixed together; a set of names in which all names are unique. The use of namespaces allows different organizations or standards to use the same names to have different meanings; the namespace can be used to identify the authority who defines the semantic meaning of a term. Essentially, the namespace qualifies a term. For example, the name "net" might have one meaning in the fishmonger namespace, and the same name, "net," have a different meaning in the the volleyball player namespace. A namespace groups identifiers in a named scope. By so specifying the scope of identifiers within the namespace of the group to which they belong, the potential for conflict between identifiers is greatly reduced. An XML Namespace is usually a Uniform Resource Indicator (URI), because the namespace may be associated with the web site or page of that URI, and because the URI is likely to be a unique name.
Defines the scope of the terms used by a metadata scheme. An element called Creator, for instance, may carry different connotations depending on whether it emanates from the Dublin Core namespace or a local, domain-specific implementation.
Provide a simple method for qualifying element and attribute names XML documents by associating them with namespaces identified by URI references; namespaces provide a means to: Distinguish between element and attribute names from different schemas or vocabularies, even if those elements or attributes have the same name Group elements and attributes together to facilitate processing See the W3C Namespaces Specification for more information. Back
A means of resolving naming conflicts by defining a globally unique name for a particular set of elements. In an XML document, you can tell which namespace an element belongs too either by checking its prefix, or by looking for the default namespace. Namespace prefixes are defined with the xmlns attribute.
A scoping device used for uniquely identifying registered entities. Identically named entities in different namespaces can be distinguished. A namespace is identified via a URL including a name and version identifier.
A unique name that identifies an organization that has developed an XML schema. A namespace is identified via a Uniform Resource Identifier (a URL or URN). For example, the namespace for Dublin Core elements and qualifiers would be expressed respectively in XML as: xmlns:dc = "http://dublincore.org/elements/1.0/" xmlns:dcq = "http://dublincore.org/qualifiers/1.0/" The use of namespaces allows the definition of an element to be unambiguously identified with a URI, even though the label "title" alone might occur in many metadata sets. In more general terms, one can think of any closed set of names as a namespace. Thus, a controlled vocabulary such as the Library of Congress Subject Headings, a set of metadata elements such as DC, or the set of all URLs in a given domain can be thought of as a namespace that is managed by the authority that is in charge of that particular set of terms.
A unit for grouping classes and instances to control their scope and visibility. Namespaces are not physical locations; they are more like logical databases containing specific classes and instances. Namespaces are represented by the __Namespace system class or a class derived from it.
An XML namespace is a collection of names, identified by a URI reference [RFC2396], which are used in XML documents as element types and attribute names. XML namespaces differ from the "namespaces" conventionally used in computing disciplines in that the XML version has internal structure and is not, mathematically speaking, a set. These issues are discussed in " A. The Internal Structure of XML Namespaces". (Source: Namespaces in XML, World Wide Web Consortium 14-January-1999)
A declarative region of a program, which can be used to access entities declared in that namespace.
A set of names in which a specified ID must be unique.
A logical naming scheme for grouping related types. The .NET Framework uses a hierarchical naming scheme for grouping types into logical categories of related functionality, such as the ASP.NET technology or remoting functionality. Design tools can use namespaces to make it easier for developers to browse and reference types in their code. A single assembly can contain types whose hierarchical names have different namespace roots, and a logical namespace root can span multiple assemblies. In the .NET Framework, a namespace is a logical design-time naming convenience, whereas an assembly establishes the name scope for types at run time. See also: assembly.
A unique identifier that can be associated with a set of XML elements and attributes. This identifier is a URI that isn't required to point to an actual resource but must "belong" to the author of these elements and attributes. Because the full URI can't be included in the name of each element and attribute, a namespace prefix is assigned to the namespace URI using a namespace declaration. This prefix is added to the local name of the elements and attributes to form a qualified name. Namespaces are optional, and elements and attributes may have no namespaces attached.
Namespaces provide a simple method for qualifying element and attribute names used in XML documents by associating them with namespaces identified by URIs (Universal Resource Indicators)

a closed set of names or a place where a schema (set of names) is stored. Namespaces are identified via a URI (for example, a URL) and are a mechanism to resolve naming conflicts. Within a given namespace all names must be unique, although the same name may be used with a different meaning in a different namespace.
A set of names in which all names are uniquely identified. This allows an object to be described without ambiguity.

A URI which points to a schema. An XML document can point to more than one namespace and hence extend its vocabulary of terms and definitions.
A, usually named, region of an enclosing namespace in which declared names will be distinct from identical names declared elsewhere. The outermost namespace is the global space, which is always implicitly provided and has no name.
The term to describe a set of related element names or attributes within an XML document. The namespace syntax and its usage is defined by a W3C Recommendation. For example, the xsl:apply-templates/ element is identified as part of the XSL namespace. Namespaces are declared in the XML document or DTD before they are used be using the following attribute syntax:- xmlns:xsl="http://www.w3.org/TR/WD-xsl".
(1) In XML, a uniform resource identifier (URI) that provides a unique name to associate with all the elements and type definitions in a schema.(2) Space reserved by a file system to contain the names of its objects.
b . A feature of XML for using multiple vocabularies in a single XML document. See: Vocabulary
See XML Namespace
A standard that lets you specify a unique label to the set of element names defined by a DTD. A document using that DTD can be included in any other document without having a conflict between element names. The elements defined in your DTD are then uniquely identified so that, for example, the parser can tell when an element called name should be interpreted according to your DTD, rather than using the definition for an element called "name" in a different DTD.
A set of space in a program reserved for naming variables, hashes, array, files etc. If a "name" is declared within a namespace, it stays constant until the program terminates. If the "name" is redeclared, it will overwrite the original value. Multiple namespaces can exist within a program.
Different XML applications or languages may use the same tags to mean different things. If you use multiple XML-based languages within the same document this may cause confusion. To prevent this, each XML-based language defines a namespace that distinguishes its tags from the tags of other languages.
In XML, the means to support elements from different DTDs in the same document. The set of elements from each DTD is said to occupy its own namespace. An element in a given namespace can be identified by assigning a namespace prefix that is attached to element names, as for example fo:inline.
A particular set of elements and attributes identified by a URI and labeled using a designated namespace prefix and a colon in front of the element or attribute name.
bindings whose denotations are restricted to a particular kind. The bindings of names to tags is the tag namespace. 2. any mapping whose domain is a set of names. A package defines a namespace.
A logical, hierarchical naming scheme for grouping related types. For example, DNS, NetBIOS, and LDAP.
A qualifier added to an XML tag to ensure uniqueness among XML elements.
A high-level context specifier that allows branch names to be reused by independent groups. A namespace is combined with a Tag to form a Branch Name. rPath will maintain a registry of namespace identifiers to prevent conflicts. Use local for branches that will never need to be shared with other organizations.
A commonly distributed set of names in which all names are unique. [Source: MALAMUD
namespace - A logical collection of properties in an Exchange store schema. A namespace serves to group related properties together for easy property discovery and, more importantly, to keep the property names unique. A Domain Name System (DNS) name creates a namespace; for example, microsoft.com.
A mechanism that uniquely qualifies element names and relationships so as to avoid name collisions on elements that have the same name but are coming from multiple sources. iddoo maqaa View
A way of qualifying element and attribute names used in XML documents. See XML, XML Schema, URI, and http://www.xmlinfo.com/namespaces/.
A mechanism that allows developers to uniquely qualify the element names and relationships and to make these names recognizable. By doing so, they can avoid name collisions on elements that have the same name but are defined in different vocabularies. They allow tags from multiple namespaces to be mixed, which is essential if data is coming from multiple sources. Namespaces ensure that element names do not conflict, and clarify who defined which term. A namespace identifies an XML vocabulary defined within a URN. An attribute on an element, attribute, or entity reference associates a short name with the URN that defines the namespace; that short name is then used as a prefix to the element, attribute, or entity reference name to uniquely identify the namespace. Namespace references have scope. All child nodes beneath the node that specifies the namespace inherit that namespace. This allows nonqualified names to use the default namespace. See also RDF namespace.
A part of the model in which the names may be defined and used. Within a namespace, each name has a unique meaning. See: name.
A named collection of names. A namespace is named by using a URI, to ensure uniqueness, and utilizes a preface to provide context for elements and attributes.
A set of unique symbols or identifiers; a collection of symbols related by function or vendor.
A naming convention to use in order to avoid name collisions. In Visio XML documents, xmlns statements specify a schema. For example, xmlns="urn:schemas-microsoft-com:office:visio"
n. A context within which names (identifiers) may be defined. There are several namespaces in C; for example, an ordinary identifier can have the same name as a structure tag, without ambiguity. See question 1.29.
A URI (Universal Resource Identifier) that qualifies an element or attribute name so as to avoid name conflicts when a document contains XML from different sources. You declare a namespace in the start tag of an element by appending a prefix to the predefined xmlns attribute (separated by a colon), and then associating this with the value of the URI; for example:h:table xmlns:h="http://www.w3.org/TR/html4/" Thereafter, you need only use a namespace prefix (â€œhâ€ in the above example) with an element (separated by a colon) to identify the element unambiguously. All child elements of the element with the namespace declaration are associated with the same namespace through the prefix. The prefix-element name combination ( h:table from the example above) is called a qualified name. A namespace declaration with no prefix after xmlns defines a default namespace, unless the value is an empty string, which means â€œno namespace.â€ The URI in a namespace declaration doesnâ€(tm)t have to point to anything; it is just a convenient way to get a unique name.
The set of unique names used to identify objects within a well-defined domain, particularly relevant for XML applications. For example, the following element names constitute the Dublin Core Metadata Element Set namespace: DC.Creator, DC.Title, DC.Contributor, DC.Description. DC.Subject, DC.Coverage, DC.Relation, DC.Publisher, DC.Date, DC.Format, DC.Identifier, DC.Rights, DC.Language, DC.Type, DC.Source.
A set of unique names for resources or items used in a shared computing environment. For Microsoft Management Console (MMC), the namespace is represented by the console tree, which displays all of the snap-ins and resources that are accessible to a console. For Domain Name System (DNS), namespace is the vertical or hierarchical structure of the domain name tree. For example, each domain label, such as host1 or example, used in a fully qualified domain name, such as host1.example.microsoft.com, indicates a branch in the domain namespace tree. See also: console tree; Domain Name System (DNS); label; resource; snap-in
Used to assign unique names, by giving a context.
NET: A namespace is naming device for grouping related types. More than one namespace can be contained in an assembly. XML Documents: A namespace describes a set of related element names or attributes within an XML document.
A mechanism for qualifying element names to make them unique in an XML document. For example carriage would mean one thing in a railway application and another in a parcel service. If you ever combined these applications you could refer to them as rail:carriage and parcel:carriage. "rail" and "parcel" are abbreviations representing XML specifications for each of these application areas.
a space of identifiers governed by a common set of rules on syntax and semantics.
A collection of naming contexts that are grouped together.
A namespace is a collection of unique domain mames. The Internet "com" domain, for example, is a namespace that represents all commercial enterprises. ... more
A scoping construct to subdivide the set of names and their visibility within a system. In many languages, this is tied to other computational constructs, eg, classes, procedures, modules, packages. A mechanism used to resolve naming conflicts.
A namespace is a context in which a group of one or more identifiers might exist. An identifier defined in a namespace is associated with that namespace. The same identifier can be independently defined in multiple namespaces, that is, the meaning associated with an identifier defined in one namespace is independent of the same identifier declared in any other namespace.
