I'd like to have module that helps people cut through the rhetoric that arises during arguments and focus on productive discussion. It could be called either "Structured Discussion" or "Argument Reconciliation". The module would make use of the following taxonomy structure: 1. Discussion vocabulary 2. Topics would the first level of terms in the hierarchy. 3. Positions would be the second level of terms. 4. Differences between positions would be the third level of terms. Each difference would inherit two terms from the positions level. 5. Evidences required to resolve the differences would be the fourth level of terms. Each evidence would inherit one or more terms from the differences level. The module would have the following content types: 1. Topic. When viewed, a table of positions and the differences between them would be attached. 2. Position. Must have at least one term from the topic level. Revising a position creates a new position and changes the status of the old position to "abandoned" until another user becomes its advocate. A position will also be abandoned if its advocate subscribes to another position with the same term. 3. Difference. Must have exactly two terms from the positions level. When viewed, a table of evidences would be attached. A difference starts with a status of "open" and is set to "resolved" when the advocates of the opposing positions accept and reject the same set of evidence. If all differences between two positions are resolved, the advocate of the rejected position will be automatically subscribed to the accepted position. 4. Evidence. Must have at least one term from the difference level. For each difference, the author must choose which of the positions it supports. An author may not choose two opposing positions for the same evidence. When viewed, a table of investigations would be attached. Advocates of each position can mark whether they accept or reject the evidence. If the advocate of the supported position rejects the evidence and the author of an opposing position accepts it, the evidence will not be a valid part the difference between the two positions. 5. Investigation results. Must have at least one term from the evidence level. Investigation status can be either "in progress" or "complete". Each content type could have terms only from a specific level of the taxonomy tree. The content type would create a term for the next level. It would be nice to enable RSS aggregation so that topics could pull in positions from other sites, positions could pull in differences from other sites, differences could pull in evidence from other sites, and evidences could pull in investigations from other sites. Is anything like this being worked on now?
