bmesh py api:

Wrap customdata, so far you can access the data layers in a pythonic way but not manipulate the customdata yet.

provides dictionary like access to customdata layers, eg:
  texpoly = bm.faces.tex["UVMap"]
  print(bm.verts.shape.keys())  # un-intended pun, keys() works on all layers.
  print("MyInt" in bm.edges.int)  # __contains__
  layer = bm.faces.get("CheckForLayer")
