David Sidman is the founder and Chief Executive Officer of Content Directions, Inc. His 20 years of experience in IT and e-business ranges from detailed technical design to broad strategic planning, and spans many industries, from financial to retail to publishing. He has consistently approached his work in established organizations with an entrepreneurial spirit, leading innovative projects that owe their success both to buy-in from the user communities they have been designed to support, and from the real-world benefits (financial and otherwise) they bring to the organization as a whole. Mr. Sidman has been heavily involved in the DOI project since its earliest days, and believes the DOI is poised to revolutionize the electronic publication of all kinds of content. He brings a unique combination of visionary entrepreneurial zeal and sound business planning to Content Directions, with the aim of accelerating that revolution.

Prior to forming Content Directions in August 2000, Mr. Sidman was Director of New Publishing Technologies for John Wiley & Sons, Inc., a leading global publisher of print and electronic products, specializing in scientific, technical and medical books and journals; professional and consumer books and subscription services; and textbooks and other educational materials. There, Mr. Sidman was responsible for positioning Wiley as a successful electronic publisher through a combination of strategy development, internal projects enabling organic growth, and external acquisitions/investments. In 4 years he helped grow electronic product revenues 16-fold, with profitability rising more than 10-fold. In addition, he initiated the use of the Web as a new sales channel for print publications, growing this channel from nonexistence in 1996 to over $30 million today.

He initiated, funded, and often directly managed the development of many new e-businesses at Wiley, including Wiley's retail Web Catalog and Wiley's strategic use of the online sales channel to increase sales of print products. He also funded and managed an internal R&D program (which encompassed 77 projects over 4 years), and consulted extensively to line business units regarding all aspects of their electronic offerings. One of these was Wiley InterScience, Wiley's largest electronic information service (with more than 300 primary-literature scientific journals available by subscription on the Web).

Mr. Sidman was also a prime mover in the DOI project from day one: he was involved in the earliest planning stages, fostered industry-wide consensus on product design and metadata standards, helped select CNRI as a technology partner, worked closely with CNRI to develop and publicize effective prototypes, and led other publishers by example and enthusiasm.

Before his tenure at Wiley, Mr. Sidman spent more than five years managing IT systems in the financial industry. He was IT Director of the International Capital Markets Division of Barclays Bank, before becoming Director of Strategic Technologies at Moody's Investors Service. Earlier, in the mid-1980's, he held technology positions at Shearson Lehman Hutton/American Express.

At Barclays, Mr. Sidman developed and deployed IT solutions which were driven by and focused on the business requirements of the firm and as a result enjoyed tremendous buy-in from users. A firm-wide business information system designed by Mr. Sidman was successfully grown from prototype to a stable production environment of 300 users in a single year, with dozens of business units signing up to pay for the optional service. This internal "revenue" grew from $0 to $1.2 million in just 15 months. The system was built to facilitate deal-making by sharing key business information across product areas, geographical locations, and business roles. It comprised more than 40 investment banking, trading, and management information applications, and captured both internal and external information on deals, clients, and products. Many applications were custom-built to extract information from the firm's trading, transaction processing, accounting, and other production systems, and to bring that information into the system, thus providing executives and middle managers with convenient access to actual production information, without a risky and costly re-tooling of the transaction systems themselves.

He also stabilized and streamlined the overall technical environment of the department, led a project which secured executive approval for a $22 million development effort for business units in the US, and consolidated and "right-sized" two major operations areas, realizing millions of dollars in savings.

At Moody's, Mr. Sidman reported to the CIO and assisted in formulating overall technology strategy for the company that was forward-looking but solidly grounded in actual business requirements. He participated in the rollout of an electronic information service which generated approximately $1 million in revenue after just one year of operation. He formed a coalition of Marketing and Technology staff from all line business units to co-develop Moody's first website. He organized an informal coalition of major information vendors (Bloomberg, Dow Jones/Telerate, Thomson Financial and others) to collaborate on an issue of common concern to the industry. Internally, he assisted in a Technology Department re-engineering effort which reduced headcount and expenses by approximately 10% with no loss of service.

Prior to Mr. Sidman's Wall Street years, he worked for a $2 billion department store conglomerate (Mercantile Stores), where he pioneered the use of EDI and the bar code (UPC) in store point-of-sale systems, inventory-tracking systems, and just-in-time replenishment ordering. He also designed and implemented a large-scale Information Systems Plan addressing communication requirements between the stores, the buyers, and corporate headquarters.

Mr. Sidman has also run technology and operations for one of New York City's largest law firms (Finley, Kumble, Wagner) and one of the world's largest international professional societies (the American Society of Civil Engineers). Prior to these positions (and just out of college), he apprenticed at Planning Systems International in Cambridge, MA, writing white papers on the state of the art of various technologies of that time (1978-80) including large-scale computer networking, database architecture, and computer-based simulation.

While an undergraduate at Harvard University (from which he graduated summa cum laude, Phi Beta Kappa in 1978), Mr. Sidman taught in an epistemology course entitled "Space, Time and Motion," which examined a number of fundamental concepts in philosophy in light of the working assumptions and definitions of those concepts employed within various fields of contemporary scientific study. These fields included Special Relativity, Mathematical Logic, the Biology of Perception, and Human Cognitive Development.

During college and for several years thereafter, he also pursued a career as a Jazz musician, composer, and bandleader. He led his own band at top-tier international Jazz festivals and clubs, and produced two commercially-published recordings of his own music.

Mr. Sidman is uniquely positioned to drive Content Directions to success—not only through his in-depth understanding of DOI concepts, technology, and implementation, but also through his industry contacts, reputation, and professional experience, which spans publishing, technology, finance, retail, consulting, and business development.
