Generic Apps

At the last Declarative Amsterdam...

I gave a tutorial on developing a 'generic' XForms application.

I had noticed that many of the applications I wrote had a similar structure, so I designed a generic structure that would work for them all:

data.xml: where the app's data is stored
meta.xml: data about the data
app.css: the stylesheets
xform.xhtml: the application, with places marked that could be edited.

I then started converting my apps one by one into the generic form; in the process often becoming much better.

Recipes

Moving away from a text-based app for notes, I had started to develop a recipes app

V1

This is the original

V2

This is the revised version based on the generic app

A recipe

Editing the number of people it serves, changes te amounts for the ingredients
