We do a lot of work with services such as Dabble and Caspio. These are data import/hosting/collaboration services.
I would like to see a module that allows for:
-- The import of Excel / CSV / tab-delimited data sets through an upload interface.
-- The conversion of this data into a SQL table.
-- The registration of a menu item to view this data as a sortable set.
-- The creation of editing tools that read the data structure and create a form for modifying or extending the data set.
-- The ability to assign Create / Edit / Delete permissions on the data to specific roles and users.
-- The option to convert this data to a node, where the node body is replaced by the data table.
-- The ability to create and define new data sets -- similar to CCK or webform functionality for content creation.
The module should be extensible, with the ability to add basic calculation features and some graphing options.
Note that I am not asking for a duplicate of Google Docs. I want to be able to import existing data from a file into a shared presentation and editing environment.
