[MOBY-dev] [MOBY-l] Cleaning the registry

[Andreas Groscurth]

Hi,

I uploaded to html files showing the unsused elements:

http://bioinfo.mpiz-koeln.mpg.de/datatypes2Delete.html
http://bioinfo.mpiz-koeln.mpg.de/namespaces2Delete.html

The corrected number for the datatypes is 331 / 721 (45%).

I assume that people register their namespaces / datatypes in advance to 
their service. So of course their mightbe elements which will be used in 
the near future - I'm not talking about cleaning it every week or so. 
But thinking about a monthly basis is fair to me and via the LSID it can 
be checked how old the entry is.

As you can see on the page - there are entries unused which are 
registered in 2001 etc...


Cheers
Andreas
