In its simplest form, a Namespace Routing Language (NRL) schema consists of a mapping from namespace URIs to schema URIs. An NRL schema is written in XML.

A document type definition (DTD) is a set of markup declarations that define a document type for an SGML-family markup language.
The Dublin Core Schema is a small set of vocabulary terms that can be used to describe digital resources, as well as physical resources such as books or CDs, and objects like artworks. The full set of Dublin Core metadata terms can be found on the Dublin Core Metadata Initiative (DCMI) website. The original set of 15 classic metadata terms, known as the Dublin Core Metadata Element Set (DCMES), is endorsed in the following standards documents:
A Uniform Resource Identifier (URI) is a string of characters that unambiguously identifies a particular resource. To guarantee uniformity, all URIs follow a predefined set of syntax rules, but also maintain extensibility through a separately defined hierarchical naming scheme.
Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The World Wide Web Consortium's XML 1.0 Specification of 1998 and several other related specifications—all of them free open standards—define XML.
XSD, a recommendation of the World Wide Web Consortium (W3C), specifies how to formally describe the elements in an Extensible Markup Language (XML) document. It can be used by programmers to verify each piece of item content in a document. They can check if it adheres to the description of the element it is placed in.
A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the urn scheme.
Document Schema Definition Languages (DSDL) is a framework within which multiple validation tasks of different types can be applied to an XML document in order to achieve more complete validation results than just the application of a single technology.
In computing, Resource Directory Description Language (RDDL) is an extension of XHTML Basic 1.0. An RDDL document, called a Resource Directory, provides a package of information about some target. The targets which RDDL was designed to describe are XML namespaces. The specification for RDDL has no official standing and has not been considered nor approved by any organization.
The Electronic Product Code (EPC) is designed as a universal identifier that provides a unique identity for every physical object anywhere in the world, for all time. The EPC structure is defined in the EPCglobal Tag Data Standard, which is an open standard freely available for download from the website of EPCglobal, Inc.. The canonical representation of an EPC is a URI, namely the 'pure-identity URI' representation that is intended for use when referring to a specific physical object in communications about EPCs among information systems and business application software.
An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself. These constraints are generally expressed using some combination of grammatical rules governing the order of elements, Boolean predicates that the content must satisfy, data types governing the content of elements and attributes, and more specialized rules such as uniqueness and referential integrity constraints.
XML namespaces are used for providing uniquely named elements and attributes in an XML document. They are defined in a W3C recommendation. An XML instance may contain element or attribute names from more than one XML vocabulary. If each vocabulary is given a namespace, the ambiguity between identically named elements or attributes can be resolved.
XML Information Set is a W3C specification describing an abstract data model of an XML document in terms of a set of information items. The definitions in the XML Information Set specification are meant to be used in other specifications that need to refer to the information in a well-formed XML document.
The AgMES initiative was developed by the Food and Agriculture Organization (FAO) of the United Nations and aims to encompass issues of semantic standards in the domain of agriculture with respect to description, resource discovery, interoperability and data exchange for different types of information resources.
The Oxygen XML Editor is a multi-platform XML editor, XSLT/XQuery debugger and profiler with Unicode support. It is a Java application, so it can run in Windows, Mac OS X, and Linux. It also has a version that can run as an Eclipse plugin.
Namespace-based Validation Dispatching Language (NVDL) is an XML schema language for validating XML documents that integrate with multiple namespaces. It is an ISO/IEC standard, and it is Part 4 of the DSDL schema specification. Much of the work on NVDL is based on the older Namespace Routing Language.
NRL refers to the National Rugby League, the top professional league of Australasian rugby league football clubs.
A Formal Public Identifier (FPI) is a short piece of specially formatted text that may be used to uniquely identify a product, specification or document. One of their most common uses is as part of document type definitions, but they are also used in the vCard and iCalendar formats to identify the software product that has generated data.
XPath is a query language for selecting nodes from an XML document. In addition, XPath may be used to compute values from the content of an XML document. XPath was defined by the World Wide Web Consortium (W3C).
In computing, info is a Uniform Resource Identifier (URI) scheme which enables identifiers from public namespaces to be represented as URIs, when they would otherwise have no canonical URL form, such as Library of Congress identifiers, Handle System handles, and Digital object identifiers.
XPath 3 is the latest version of the XML Path Language, a query language for selecting nodes in XML documents. It supersedes XPath 1.0 and XPath 2.0.
