The rural area where I live has a lot of Greens and Commons. How can I define these on the map? Similarly, can I map areas of woodland and field boundaries?

There is both a technical and a ontological dimension to this question.

Technically, the way to define an area, which is not a separate feature type in the OpenStreetMap data model, is to create a way (line) that has a common first and last point: a closed way. See here for the relevant information on the OpenStreetMap Wiki.

Depending on how you tag your closed way, it will be rendered as an area on the map. The Map Features page on the OpenStreetMap wiki will give you an indication as to which tags can be applied to closed ways in order to have them redered as visible areas. For example, tagging a closed way as landuse=village_green will make that feature show up as a green area on the rendered map. Key-value combinations that apply to closed ways will be indicated by the area icon on this page: alt text

Note that there are several similar key-value combinations for green areas in built-up areas: leisure=park, landuse=village_green, landuse=grass, landuse=recreation_ground, to name a few. Ask on your local mailing list or here to learn more about the sometimes intricate differences.

Areas are ways that starts and ends in the same node. Just add a way around the area and add the appropriate tags. If the area is made up of several ways or have holes in it you might be interested in the multipolygon relation.
