Manual conversion of content to HTML is not only tedious but creates a fundamental content management problem. The hand-tweaked HTML version, or a Save As HTML version, tends to become a separate source document rather than simply a rendition of the original. Each change in content made by the author needs to be implemented in the HTML version, and for minor changes the effort may not seem worth it. It is easy for Web content to quickly become out-of-date and out-of-sync with the authored source. Furthermore, when documents are added using this process, navigation links to next and previous pages and from reference documents such as Tables of Contents must be manually updated. Transit Solutions eliminate the costs associated with manual updates. The philosophy behind HTML Transit and Transit Central is that content should be maintained in a single source, i.e. in the authored format, regardless of the output format. Then, changes in the content need only be made once—by the author—allowing more timely updates of the Web-published version and clarifying “ownership” of the content accuracy. Print and Web versions of the content stay in sync. Moreover, this shifts the burden of Web publishing away from the Webmaster bottleneck and back to the authors. But the shift is subtle. Authors are completely shielded from HTML and continue to work in their standard editing applications.
