A problem that I can see with the second <Author> segment is that it would be difficult to add extra information at a later date, such as address, contact details etc. Phil Meadows -----Original Message----- From: Costello, Roger L. [mailto:costello@m...] Sent: 05 March 2008 12:02 To: xml-dev@l... Subject: "Maximize the ratio of content to markup" What's the underlying principle? Hi Folks, Yesterday I read this: "Search engines look for semantic markup with a high ratio of content to code." [Building Findable Websites by Aarron Walter] For example, this is not good design: <div> <div id="Main"> <p>Hello World</p> </div> </div> The outer div is providing no benefit. It can be more simply expressed as: <div id="Main"> <p>Hello World</p> </div> The later version provides a higher ratio of content to code (tags). And from the quote above, search engines rank higher documents with a higher ratio of content to code. What is the underlying principle? Why do search engines prefer documents with a higher ratio of content to markup? Can the principle be applied to XML data design? For example, This is not good design: <Author> <Name>Paul McCartney</Name> </Author> The Name element is providing no benefit. It can be more simply expressed as: <Author>Paul McCartney</Author> The later version provides a higher ratio of content to code (tags). What do you think? Is there a principle of data design being illustrated here? Can you articulate the principle? /Roger _______________________________________________________________________ XML-DEV is a publicly archived, unmoderated list hosted by OASIS to support XML implementation and development.
