my own interest is documenting aspects of the American Civil War. this would include both movements (which need a descriptive language) and fortifications (Rob Warren has been working on describing WWI fortifications in OHM already.) my proposed laboratory would be based on the Maryland Campaign of 1862 and the Battle of Antietam which represents the major action of that campaign. this is in part because i have a special interest in it (i have great-great grandparents who lived on the battlefield when it occurred) and in part because there is an excellent set of descriptive maps developed by E. B. Cope of the Army Corp of Engineers that was released in the early 1900s. the result is that there is detailed data available for both tactical and operational level movements and because of the time of publication by the US Government, there are no intellectual property restrictions. so what i have in mind roughly is a new relation type, call it ohm:movement it should have tags that allow description of what is moving (company, regiment, division, etc.), and start and end times for the overall movement. individual elements of the relation could be nodes (specific points) or ways (representing, for example, units marching in column or units deployed into line). these would have times (start and/or end) as well. status of units would probably be something to look at. one of the better known incidents of the Battle of Gettysburg was Stuart's cavalry ride around the Army of the Potomac. this included Stuart encountering and capturing a Federal supply train. this would be something we would probably want to represent - it had a major impact on the battle (Stuart's movements slowed dramatically once he had to cope with a train of captured wagons, delaying his arrival at the battle proper.) the wagons were captured, how do we represent that change in status? i'll follow up again, there is a barely started proposal in the wiki page to which i'll provide a link when i can. richard -- [email protected] Averill Park Networking - GIS & IT Consulting OpenStreetMap - PostgreSQL - Linux Java - Web Applications - Search
