Invisible Worlds, a San Francisco-based startup company unveiled the EDGARspace portal, a new Web service that delivers refined searches of the U.S. Securities and Exchange Commission’s (SEC) EDGAR filings. The EDGARspace portal, one of the largest XML-based information systems ever developed, demonstrates the potential of XML by giving investment, financial and research professionals better ways to search for and find information that had been difficult to obtain. A trial version of the EDGARspace service is available free to the public at for the next 90 days. It will then be available by subscription. Some features will remain free.
