I'd suggest that it would be far more useful to use a marked-up file format based on XML. It doesn't have to be verbose (besides which, the bandwidth requirements of embedded graphics will be far greater than any requirements for markup used to indicate their position within the text). The reason I think this would be far more advantageous is that there has been a massive interest throughout the IT industry in XML, meaning that there are lots of software implementations that support it, and it is very easy to build processes for publishing content. You coulde probably use any commonly-used database product out there to generate XML content suited for DVB-MHP; in fact, it would be easy to take some existing XML-based publishing process and extend it to support an XML-based file format specifically intended for DVB-MHP. In contrast, if you want to invent a new file format, then you've got to create new software implementations to go with it, and bolting that into any existing publishing process will be far more costly. >Using HTML and a browser is just not the way to proceed in that situation. >HTML and a browser is a very useful technique for the web and indeed is an >option for the DVB-MHP system, yet the basic software system is Java based. Markup does not have to imply HTML and a Web browser. I'm sure you'd find a lot of Java implementations that made use of XML-based file formats, and though I'm not a Java programmer, I'm certain that you can find good support for parsing or generating XML streams in Java. - Peter --------------------------------------------------------------------------- Peter Constable Non-Roman Script Initiative, SIL International 7500 W.
