I didn't see GMPLS defined in Ruyter's email, so I'll add the internet-draft definition (www.ietf.org). Generalized-MPLS (GMPLS) extends the MPLS control plane to encompass time-division, wavelength and spatial switching. A functional description of the extensions to MPLS signaling needed to support the new types of switching is provided in [GMPLS-SIG]. Along with the current development of IP over optical switching, there are considerable developments in optical transport systems based on the multiple optical switching granularities. [GMPLS-SIG] currently defines two layers of optical granularity (wavelength and fiber). As described in [IPO-MG], a revisited definition of waveband switching must be introduced. This document presents a functional description of the extensions, to the GMPLS protocol suite, to integrate the additional requirements of optical multi-granularity and to further benefit from the features of those switching layers.

Is there an official one or has there been an attempt to establish one and post it on the net so that we can all understand each other better.
