The current chunk was contiguously filled with all the incoming data: directorydescriptors, segments descriptors, segment data, or image descriptors. When the current chunkwas (nearly) full, it was copied to a newly allocated chunk, and reset for new use. This had 3major limitations:• it was a permanent worry to make sure that the incoming data will fit in the remainingplace of the current chunk,• the tree size and the numbers of images in the tree were limited by hard coded parametersin the source code,• the various links in the tree between the directories, the segments, and their data, wereremembering the chunk number and the position in the chunk. Deleting an object andfreeing its associated memory was just a nightmare: links could not be updated easily.Table 5: Old GTV symbols which are removed, and the command which can be used to definethem in user’s ∼/.gag.dico .

The relationship presented herebetween the various elements is not exhaustive.Given these limitations, the choice was made to fully rewrite the way the metacode data isstored in memory. Appropriate Fortran derived types were defined: they describe the variouslinks an object can have with others in the tree. Figure 1 shows an example of the various kind
