 Not quite. Data models require stronger and deeper agreements than the syntax. They typically work for smaller groups. Syntax agreements are relatively easy to get. Keep in mind that the most successful syntax agreement is CSV, not XML. XML came about because it had been shown to work in the generation of markup users that preceded it reasonably well, and because the web was perceived as a no lose money maker and folks were in the mood to deal. Data models have a place. I don't think any given model works as well in as many cases as a syntax agreement does, but they still work for those who know how to use them for what they understand and can communicate well. It is an issue of scale. But as one who lived in the previous generation of SGML tools that did not have any hint of a common data model, I have to say I don't want to go back there. The infoset has its uses. I agree that programmers usually prefer to work at the level of the API, but things like hidden namespace values force them to go back and look at the data model. len From: Tim Bray [mailto:tbray@t...] Yes, and I want a car that runs on water and get 100mpg, but it ain't gonna happen. The reason XML has taken off is that generation after generation of attempts to interoperate at the datamodel/API level has either failed or provided poor price/performance. Syntax is a qualitatively, consistently, dramatically better basis for interoperation; desires to interoperate at the data model level, no matter how reasonable, are apt to remain unfulfilled for the foreseable future. -Tim
