Great, it's good to see other efforts in this area, and I'm definitely interested in collaborating. I want to stress, however, that Cartagen is not necessarily an OSM renderer, but a mapping framework in general - it can consume the OSM API, but also KML and other data sources. One thing I really like about the osmarender frontend project is that beyond trying to be a wysiwyg map editor, it uses a style markup similar to what I've been doing in Cartagen... the rules file: http://wiki.openstreetmap.org/wiki/Osmarender/Rules#Example_of_using_embedded_CSS_styles
We should definitely work together on a common style format - i've tried to make Cartagen run on something very close to CSS, which is why I've called it GSS - the idea being that web developers who are used to CSS can use their literacy to design maps as well: http://cartagen.org/glop/style.gss The nice thing about GSS is that it's actually JSON - meaning that instead of static styles like: footway: { lineWidth: 2, strokeStyle: "#842" }, we also can write actual code in a style, like: way: { strokeStyle: function() { return color_from_string(this.user) }, lineWidth: 2, fillStyle: "white" }, The above converts the user name of the contributor (from OSM) to a hex string useable as a color. So what you see is something like this: http://map.cartagen.org/?gss=http://unterbahn.com/cartagen/style.gss This is why i see Cartagen as more than a renderer, but a fully scriptable map design framework.
