"I have been using OmniMark for a decade to solve many different kinds of information management problems. When OmniMark Technologies Corporation added features to their excellent language that allowed server functionality and database access, OmniMark became an even better, more powerful platform for data processing. When they made it free, it made me wonder why anyone is still using Perl. I have used OmniMark as a very stable middle-tier programming language that is lightning fast, scaleable, and really fun to use. The language has a certain elegance that, once you learn how to `think OmniMark', you never want to even consider the alternatives. The native hierarchical architecture of the language, plus its luxuriously rich pattern matching syntax and support for structured information using XML and SGML parsing, make OmniMark a real joy. "This book covers the core language, plus practical examples for common Internet programming applications. OmniMark is such a powerful program that I can't think of any Internet programming problem that can't be solved with OmniMark. This book makes that clear in real, understandable terms." -Brian Travis, is the author of OmniMark At Work Volume 1: Getting Started and XML and SOAP Programming for Biz-Talk® Servers "OmniMark has been the secret weapon of markup language programmers since the earliest days of SGML. Its new XML support should bring it to a far wider audience." -Charles F. Goldfarb, is the inventor of SGML and author of The XML Handbook.

The law of secured credit is both very important and very complex. Perhaps because of this, law students, lawyers, judges, and lawmakers struggle to master its many nuances. Secured credit law may not have the initial appeal that criminal or constitutional law hold in the minds of many, but it forms the backbone of everything from day-to-day consumer transactions to large-scale commercial financing, both around the corner and across the world.

The "SGML Buyer's Guide" helps experts and beginners to analyze the publishing process and to evaluate and choose the best tools and services for their needs. It also presents a new methodology, developed by the authors, that simplifies and optimizes publishing systems. The CD-ROM contains a professionally chosen selection of SGML and XML freeware, a graphics package, and demos of many commercial SGML software packages.

The World Wide Web presents many new, exciting prospects for geographic information systems, but also numerous technical, practical and organizational challenges. Users no longer require specialized and expensive hardware, software and data, and they can access a GIS readily from almost anywhere, using off-the-shelf browser software. An onli

Peter Flynn has been an enthusiastic and skillful contributor in the world of SGML and XML for many years, and it is a pleasure to see him set some of his expertise down in writing as well. The range and power of SGML tools have taken a sharp upward turn: the first step leading to this was that the Web came along with HTML, and showed the whole world that pointy brackets and (at least somewhat) descriptive markup could make a difference. Soon afterward, 'HTML claustrophobia' began to grow and XML came to the rescue. Since XML is fundamentally an elegant subset of SGML that reduces complexity without reducing functionality, the movement to XML is great for SGML too. The massive interest in XML is bringing forth a huge variety of new, faster, more powerful, and cheaper software tools. Peter has caught the cusp of this change and shows in detail how SGML and XML tools fit together into integrated solutions that return value for your investment in structured information.
