The Dublin Core Metadata Initiative is an open organization engaged in the development of interoperable online metadata standards that support a broad range of purposes and business models. DCMI's activities include work on architecture and modeling, discussions and collaborative work in DCMI Communities and DCMI Task Groups, annual conferences and workshops, standards liaison, and educational efforts to promote widespread acceptance of metadata standards and practices.

The Tabulator project is a generic data browser and editor. Using outline and table modes, it provides a way to browse RDF data on the web. RDF is the standard for inter-application data exchange.
You can use it in two ways
As a Firefox Add-on
The tabulator extension is a Firefox extension which allows Firefox to handle data as well as documents. Install it from the tabulator extension page
As a web application
The tabulator online version is a set of open source Javascript scripts ("AJAX") which can run in any web page to add data browsing. It currently runs with Firefox, (or as an Opera Widget) and requires Firefox preferences to be set -- see the tabulator help page or the sidebar on the right.
* First: configure Firefox
Before you try an online version:
1. Type into the main browser URI bar "about:config" and hit return to get to the config page.
2. Type codebase into the filter window
3. Double-click the line signed.applets.codebase_principal_support ... user set ... boolean .. false to change it to 'true'.
4. Go back to the tabulator, and try again. When the browser asks you whether to allow the script to access arbitrary web pages, agree. Check the "remember the answer this question" box.
The Tabulator is open source under the W3C software license.
The Resource Description Framework (RDF) is a general-purpose language for representing information in the Web.
This document defines a textual syntax for RDF called Turtle that allows RDF graphs to be completely written in a compact and natural text form, with abbreviations for common usage patterns and datatypes. Turtle provides levels of compatibility with the existing N-Triples and Notation 3 formats as well as the triple pattern syntax of the SPARQL W3C Proposed Recommendation.
This document specifies a language that is in common usage under the name "Turtle". It is intended to be compatible with, and a subset of, Notation 3.

Abstract
This document provides a tutorial on how to publish Linked Data on the Web. After a general overview of the concept of Linked Data, we describe several practical recipes for publishing information as Linked Data on the Web.
The Publishing Requirements for Industry Standard Metadata (PRISM) specification defines a standard for interoperable content description, interchange, and reuse in both traditional and electronic publishing contexts. PRISM recommends the use of certain existing standards, such as XML, RDF, the Dublin Core, and various ISO specifications for locations, languages, and date/time formats. Beyond those recommendations, it defines a small number of XML namespaces and controlled vocabularies of values, in order to meet the goals listed above.
