Underlying schema for POWDER

The Protocol for Web Description Resources (POWDER) allows metadata to be associated with groups of resources such as those found on a Web site. Its main 'unit of information' is the Description Resource (DR), one or more of which are contained in a POWDER document. Processing such a document yields RDF triples describing the resources that are within the scope of the DRs. POWDER documents are written in XML and have relatively loose semantics, however, a GRDDL transform, associated with the root namespace, renders the data in RDF/OWL with more formal semantics.

Linked-data framework for connecting species in chemical kinetic reaction mechanisms with quantum calculations. A mechanism can be constructed from thermodynamic, reaction rate, and transport data that has been obtained either experimentally, computationally, or by a combination of both. In order to implement this approach, two existing ontologies, namely OntoKin, for representing chemical kinetic reaction mechanisms, and OntoCompChem, for representing quantum chemistry calculations, are extended.

he WOT, or Web Of Trust, schema is designed to facilitate the use of Public Key Cryptography tools such as PGP or GPG to sign RDF documents and document these signatures.

an ontology for links and forms, the main hypermedia controls in use on the Web. This ontology offers, among others, a means to reify RDF statements interpreted as links between Web resources. It also provides a versatile exchange format for links and forms in RESTful Web applications. [from homepage]

an RDF vocabulary for the security metadata definitions

The Thing Model (TM) ontology is an RDF axiomatization of the TM concepts, one of the building blocks of the Web of Things (WoT). Besides providing an alternative to the standard JSON representation format for TM documents, the TM ontology can also be used to process contextual information on Things and for alignments with other WoT-related ontologies.

WWF ecoregions are large unit of land or water containing a geographically distinct assemblage of species, natural communities, and environmental conditions.

This is a vocabulary collection utilized by XHTML Family modules and document types using XHTML Modularization, including XHTML Role and XHTML + RDFa as defined in rdfa-syntax. The XHTML specifications are developed by the W3C XHTML 2 Working Group as part of the W3C HTML Activity. [from homepage]

The Extensible Markup Language (XML) is a subset of SGML that is completely described in this document. Its goal is to enable generic SGML to be served, received, and processed on the Web in the way that is now possible with HTML. XML has been designed for ease of implementation and for interoperability with both SGML and HTML.

This document describes the XML Schema namespace. It also contains a directory of links to these related resources, using Resource Directory Description Language.
