Update: For some background on this particular inscription see Tom's post on the demarcation between Thraces and Moesi.
The subject of digitally annotating texts and art works came up at last fall's NEH/CNR conference, and I thought: we could do that with OpenLayers. Recently, I read this post at the Stoa Consortium and thought: we could really do this with OpenLayers. And that's what we did today at the Pleiades skunk works: put a photo of an inscribed stone in an OpenLayers image layer, drew polylines over it in a vector layer, and then wrote the layer out to SVG: http://sgillies.net/images/MXITRIB.svg.
Feel free to try it out: http://atlantides.org/inscriptol/. Once we add the capability to edit or delete polylines, add text annotations/metadata, and save the results this could be the beginning of a useful tool. Check out that nifty SVG transform group: maybe I haven't lost all my linear algebra yet.
OpenLayers simply rocks.
