Implementation requirements prevented the use of a HyTime engine, though the project demanded HyTime functionality with good performance. The implementation chosen was straight-forward to build, uses commonly available free tools, shows adequate performance, and offers convenient paths for optimizations if and when they are needed. The official publication date of the Second Edition of HyTime was August 1, 1997. Colin Gajraj, Nortel Nortel is a large, international telecommunications company whose documentation needs are diverse and changing. The use of inheritable SGML architectures allows diverse document types to have well-defined, validatable structures in common.
Generic tools can operate on documents conforming to specific classes.
This presentation briefly describes Nortel's work with architectures so far and also touches on future work. Isogen International Manually creating and verifying links to external document objects using a HyTime model can be intimidating, confusing, and difficult for many authors. Unfortunately most of the SGML authoring tools today offer limited or no support for HyTime out of the box. However, through tool customization, HyTime addressing can become automated. This presentation describes and demonstrates one company's implementation that makes HyTime addressing completely transparent for their authors.
