Create the form as an instance method of the ZClass (under the methods
tab). Then just insert the property values like:

<input type="text" name="location" value="&dtml-location;">

Make sure that the names of the form fields match exactly with your
property names.

The action method (which should also be an instance method of the
ZClass) should look something like this:

<dtml-call
expr="propertysheets.date_properties.manage_changeProperties(REQUEST)">
<dtml-call name="reindex_object">   <--- If it is CatalogAware
<dtml-call expr="REPONSE.redirect('index_html')">
