Let's say I have a table full of structured data about a couple hundred objects. There exist conceptual groupings and hierarchies of these objects, but these relationships are not yet codified anywhere in the data.
What is a tool I could use to create these groupings and relationships? This does not have to be inter-operable with any existing software, but it must be able to import some of the structured information about these objects (name, id, description, a couple of attributes), and export structured data about the relationships that result from the work in this tool or application.
What I would like to do is organize these objects into a hierarchy, create dependency relationships, and also create arbitrary groupings of selected objects. I would like to do this using common keyboard-and-mouse paradigms such as multiple select and click-and-drag. Are there any tools that exist that could allow me to do these things with imported data using a graphical interface?
