[edit] Are you happy about the PDB remediation?
The recent remediation project has cleaned up a lot of data in the PDB but has also introduced important changes to the data format. As an example, all chains which previously had no chain code are now annotated as chain 'A'. This may be a problem for existing databases and tools because mapping the new to the old chains is not trivial. Is the remediation still overall a good thing or would we have been better off keeping the old data?
[edit] When will we run out of PDB codes?
Most PDB codes starting with '1' have already been assigned. Even if all digits for the first character will be used, at some point we will run out of pdb codes. What should we replace the old codes with? A five-letter code, adding an additional character? Or a completely new scheme with some mapping function which would translate old into new codes?
