Hi, I tried out the ActiveRDF library for accessing RDF data from Ruby and it worked very well. Now I''m interested to combine ActiveRDF and Rails by using e.g. the YARS data-store instead of ActiceRecord in a RoR project. For this I downloaded the ''browserdf'' example. Now I need some help or ins...

I''m very uncomfortable with Rails right now because it seems to be totally wedded to relational databases. I want to develop my data and data structures in Tinderbox - a hypertext data development system from Eastgate systems (http://www.eastgate.com/Tinderbox/), export the data and datastructures, massage to some format, and then use with a dynamic frontend that builds a web page

The ActiveRecord concept seems to allow me to set up something that works with an existing table, but I want the ability to add tables without programming.

I want to build an application that lets me (the end user accessing a web page) design a simple list with columns and add records. E.g., if the end user says I want a table that has a list of songs, he can create a list (title, date, artist, label) and then make another list of, e.g., books on his bookshelf with the necessary columns (title, author, pub_date, shelf).
