Hi Stuart,
Please forget the dtp studio PDF file. It's outdated and was never meant to be a digital colour reference, only a preview of the physical product. The new PDF will be a multi-layer file, with colour values for several output targets (spectral colours, L*a*b*, sRGB, at least one CMYK target, probably ISO Coated v.2). There will also be a new SOC file available (unless you plan to implement an import filter for CxF files), which will be called "DIN-CIEHLC" or something like that. Since CxF allows multiple versions of the "same" colours in one file, we'll probably release one single CxF palette with at least spectral colours, L*a*b* colours and sRGB colours.
