------------------------------------------------- The International Press Telecommunications Council and the Newspaper Association of America have just released the (production) version 2 of the News Industry Text format (NITF) DTD. See http://www.iptc.org/iptc This DTD is designed for news information distribution and has little structural, but significant content mark-up. During development we have attempted to include the HyTime ILINK capablity as this is important to news providers who cannot afford to delay the news in order to enter links. As Panorama Pro is the only browser I know that can display and resolve at least some HyTime link functions this was used for testing the DTD. Although this browser proved capable of reading and partially interpreting NITF SGML document instances that only contain linking information in a similar form to that produced by Panorama it has a mind of its own. The browser promptly rewrites such files into its own web format. The crunch appears to be the statement in the HyTime standard that ILINK implementation is vendor specific. Can anyone help by commenting on our method of including the HyTime links in the DTD and how we might provide full testing of this functionality? -- David Allen MD IPTC Serving the news movers ho73@dial.pipex.com visit www.iptc.org/iptc
