Explorator is a tool for exploring RDF data by direct manipulation. Explorator’s web interface allows users to explore a semi-structured RDF database to both gain knowledge and answer specific questions about a domain, through browsing, search, and exploration mechanisms.
A simple but powerful service that delivers RDF-based structured descriptions of Web addressable resources (documents or real world objects) in a variety of formats through Generic HTTP URIs.
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.
