Standard & Poor's is making its Crosswalk product – a joint venture with Dun & Bradstreet and Telekurs Financial – available via the web. Crosswalk, backed by sizeable players in the business entity identifier space, identifies the link between securities, issuers and their corporate entity hierarchy. Meanwhile, the company has also launched Ratings IQuery for fixed income. The web-based research and reporting tool provides users with functionality for mining its historical credit ratings database. This is available alongside S&P's RatingsDirect credit research service, and the RatingsXpress data feed.
