RE: Which should come first: code, XML Schema, or binaryspecif

Hi Roger

Of course your question needs some framing of its assumptions first. Where does the question sit in the spectrum between Agile/ExtremeProgramming and the more formal/traditional development processes? If it's assuming Agile development then I'd say the code comes first and the schema and spec might never come at all or perhaps an XML Schema might come next and spec never appear at all.

Hi Folks,

I am examining Microsoft Visio.

It is a nice drawing application. You can create neat pictures.

You can save your drawing as a binary file.

You can also save your drawing as an XML file which conforms to an XML Schema for Visio.

So there are three components:

1. Code which expresses the capabilities of the application

2. XML Schema which expresses the capabilities of the application

3. Binary specification which expresses the capabilities of the application

In the development of an application which should come first: code, XML Schema, or binary specification?
