Protocol for Web Description Resources (POWDER): POWDER XML Schema (WDR) W3C Working Group Draft 13 February 2009 http://www.w3.org/2007/05/powder-2009-02-13/ Kevin Smith, Vodafone Group R & D Andrea Perego, Università degli Studi dell'Insubria all members of the POWDER Working Group

This is the namespace document for the POWDER XML schema. It defines a set of high level IRI constraints for Internet-based IRIs.

This namespace document describes the POWDER XML schema, which extends and re-defines the POWDER-BASE XML schema [POWDER-BASE], by defining a set of high level IRI constraints, for Internet-based IRI, denoted by the fact that they all include a host component (such as IRIs with schemes http and ftp).

More precisely, it defines a new set of child elements of iriset, plus an element, namely abouthosts, which is used instead of the aboutregex element defined in POWDER-BASE.

Enabling Read Access for Web Resources A. van Kesteren. W3C Working Draft 1 October 2007. This document is at http://www.w3.org/TR/2007/WD-access-control-20071001/#access0.

This type re-defines the structure of the attribution element, by substituting element aboutregex with abouthosts.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the host component ends with string S₁ OR … OR string S_n. This element can occur at most one time as a child of the attribution element.

This type re-defines the structure of the iriset element, by defining a set of elements, expressing high level constraints on IRIs.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the scheme component starts with string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the scheme component does not start with string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the host component ends with string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the scheme component does not end with string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the port component matches string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the port component does not match string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the path component matches string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the path component does not match string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the path component contains string S₁ OR … OR string S_n. This element can occur 0 or more times as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the path component does not contain string S₁ OR … OR string S_n. This element can occur 0 or more times as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the path component starts with string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the path component does not starts with string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the path component ends with string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs where the path component does not end with string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This element takes as value a string S, denoting the set of IRIs where the query component contains string S. This element can occur 0 or more times as a child of the iriset element.

This element takes as value a string S, denoting the set of IRIs where the query component does not contain string S. This element can occur 0 or more times as a child of the iriset element.

This element takes as value an IRI pattern, specified according to the syntax of an access item, as defined in [WAF], denoting the set of IRIs matching that pattern. This element can occur at most one time as a child of the iriset element.

This element takes as value an IRI pattern, specified according to the syntax of an access item, as defined in [WAF], denoting the set of IRIs which do not match that pattern. This element can occur at most 1 time as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs matching string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This element takes as value a space-separated list of strings S₁ … S_n, denoting the set of IRIs which do not match string S₁ OR … OR string S_n. This element can occur at most one time as a child of the iriset element.

This type defines the structure of the includequerycontains and excludequerycontains elements, which consists of a string of type iriQuery, and an optional attribute delimiter, denoting the character used to separate parameter-value pairs in the IRI query string. The default value for such attribute is & ("ampersand").

This attribute is used to denote the character delimiting parameter-value pairs in elements includequerycontains and excludequerycontains.
