Re: The impact of data format selection on application development

Michael Kay quite correctly noted that the specification of my hypothetical data format is incomplete. Please, allow me to add a sentence or two to address its inadequacies:

The data format consists of lines (lines are strings that are typically separated by newlines, although the user may use a symbol other than newline, if desired). Each line contains fields. Fields are ASCII strings. Fields are separated by a delimiter (common delimiters include the tab, space, or comma symbol, although the user is free to use another symbol if desired). Fields may contain the field delimiter symbol provided the symbol is preceded by a backslash symbol (this is called "escaping the symbol"). Fields may be empty. Each line has the same number of fields.

Admittedly, those additions do result in using more ink to specify the data format. Nonetheless, it is a far cry from the dense 36 pages of the XML specification plus the 16 pages of the namespace specification. I think the data format can be fully understood in less than 30 seconds. Contrast with gaining a full understanding of the XML data format, which may take months or even years.

Thanks for the comments Michael!
