Intellidimension RDF Gateway - A platform for the Semantic Web RDF Gateway is a platform for the development and deployment of Semantic Web applications. The Semantic Web is an extension of the current Web that allows computers to understand the meaning of information published on it through the use of a new markup technology called the Resource Description Framework (RDF). RDF Gateway allows you to create an exciting new generation of intelligent Semantic Web applications in which computers help people perform their tasks faster and better!
Use RDF Gateway to create applications that automatically gather and publish information on the Semantic Web. RDF Gateway is both a Web client and a Web server with a powerful native RDF database for managing large or small amounts of information on a server or desktop computer. Create agents that intelligently populate your database with relevant information from any external source that can be described using RDF. Create Web pages that query your database to publish your information for agents on the Semantic Web and/or for people on the Web.

Powerful native RDF database engine

  • Powerful SQL-like commands for querying RDF data
  • Deductive reasoning via inference rules (libraries for OWL and RDFS)
  • High-performance disk and memory tables
  • Transactions with isolation levels
  • Virtual tables to integrate external data sources (Web pages, local documents, relational databases, legacy applications, etc.)
  • Federated queries across multiple internal and external data sources
  • Full-text searching
  • Data encryption
  • Serialization support for RDF/XML, N3, and NTriples
  • Table and statement level security
  • Data access from other applications via HTTP, Microsoft ADO or Sun Microsystems JDBC

Full-featured Web server

  • Standalone HTTP 1.1 Web server (no third-party dependencies)
  • Hosts multiple Web or Semantic Web applications
  • Compatible with existing Web servers
  • Scalable architecture supports heavy traffic
  • Server-side scripting to produce dynamic content for either the Semantic Web (using RDF) or current Web (using HTML)
  • User and role based permissions and rights to server resources
  • HTTP Authentication (clear-text, NTLM)
  • Integrated NT user and file security for external rights management
  • Sessions and cookies
  • Support for custom HTTP headers and methods to implement extended Web protocols
  • Integrate backend legacy systems or extent server functionality via Microsoft COM or CGI

Familiar easy-to-use scripting language

  • Server-side scripting language based on the popular JavaScript (ECMA Script) language
  • SQL-like commands integrated into scripting language for accessing RDF database engine
  • Server-side scripts can be embedded in Web pages along with static content (like Microsoft Active Server Pages)
  • Handle client requests via a simple object model (Session Object, Request Object, Response Object, Cookie Object, and more)
  • Integrated edit and test environment for script development
  • Execute scripts from other applications via HTTP, Microsoft ADO or Sun Microsystems JDBC

Simple installation of applications

  • Install, update, and remove applications via a step-by-step installation wizard
  • Distribute applications as a single compressed file (ZIP format) on removable media, your network, or the Internet
  • Applications have no dependencies on third-party applications or frameworks
  • Run applications with a one-time install of RDF Gateway Personal Edtion (free download for non-commercial use and/or product evaluation)

Platforms

  • Windows NT, 2000, XP
