There are three examples here: ``jquery/catalogue/simple.html`` Load a page which fetches the second sheet of a UK bebefit data spreadsheet and inserts it as HTML. ``jquery/catalogue/index.html`` A simple app built against the UK government's catalogue. Load ``index.html``, choose "Search package metadata" and try searching for ``gb-regional-benefit-expenditure``. If you click the link to the Excel file, the first sheet of the data will be shown. ``dataproxy`` An example Google App Engine app for setting up your own proxy. NB: If you set up your own app engine example you may want to copy the ``app.py`` in the ``dataproxy`` directory from the (possibly) more recent version in the ``jsonpdataproxy`` directory.
