Content Directions Inc. (CDI) helps companies increase their sales and profitability by improving the discoverability of their products and services on the Internet and within their enterprises, and by better linking their customers, business partners, and employees to those products and services. Our principal technology for this is the Digital Object Identifier (DOI), a linking system developed by the primary inventor of the Internet itself and representing “The Next-Generation URL.” CDI consults with all kinds of organizations on how to increase their revenues and cut costs, and as the first authorized commercial DOI Registration Agency, activates DOIs by registering them into the global DOI directory, similar to the way that domain names are registered into the global DNS system.
