Sean McGrath has an interesting article on XML 2001 that makes a similar point http://www.itworld.com/nl/xml_prac/01032002/ "I think my abiding memory of XML 2001 will be as the conference at which the data- heads and the doc-heads finally agreed to call it quits and go their separate ways. ...Document people see the world in terms of XML encoded information flowing through systems, perhaps undergoing transformations and validations at various stages along the way. Data people see rigid XML structures flowing over the wire between well-defined end-points that encode all the really interesting stuff in "business logic" at the end- points." Another XML 2001 presentation by Stephen Kirkham made similar points http://www.idealliance.org/papers/xml2001/papers/html/04-05- 01.html "In the Object oriented world data is a second class citizen. Objects control access to and provide operations on data. ... XML however starts to reverse the clock, it represents a change in course back to a more data centric world, one in which data has a life of it's own. Data has effectively broken free of its object boundaries" These various distinctions -- Markup vs Mainstream dataprocessing, Doc-heads vs Data-heads, Data-centric vs Object-centric, and maybe my Loosely-Coupled vs Tightly Coupled -- are pointing to many of the same things. I don't know that I agree with Sean that the two camps have called it quits and are going their separate ways, but I think it is very important to understand that these are very different use cases for XML, and one reason why we have a tendency to talk past each other when these subjects come up on xml-dev.
