Hi Lars The first version of the MBX was released now because of a separate issue. The new Ordnance Survey data is in GML format whereas it used to be in a format called NTF.
NTF will be withdrawn, so what I have also put in the MIMIC mbx is the ability to create Landline NTF files from our 64 bit format and therefore from MasterMap GML. I appreciate this might not seem relevant, but it is why I released the viewer early. The first version only builds an AOI ( area of interest ) for one map window. I have started coding for multiple windows. A table that is open in more than one window, needs an AOI for each map window. The fact that this data is built "on the fly" will allow for some interesting transforms. For example labelling on a curve is a possibility because MIMIC decides what MapInfo gets to see in its native tables! I plan to include rotation of raster and rotation of vector in a future version. With regard to your second question its not there, but its certainly a possibility. The great thing about defining a format is you can add what you like! For example a key feature of MasterMap is change only updates. Ordnance Survey can issue customers with change only data rather than full supply.It has been possible to build in features to the format that make this process very quick. I would be very interested to hear your ideas on password protection. Do you mean a password to open up through MapInfo Professional, or full encryption so that a "dos debug" user would not see text strings? With regard to sample datasets, at present it only works with GML as used by MasterMap! If there is sufficient interest in this I could write a TAB to GML(GZ) convertor and then people could try it out with their own data. Thanks for the support!
