Re: [Handle-info] Is it correct, that dx.doi.org will stop resolving handles in future?

Hello,

Starting with your second question - DOIs are handles, so  
hdl.handle.net will always resolve DOIs. Whether the behavior of  
hdl.handle.net will always mimic dx.doi.org is another question.  
Although they have a common code base, these are definitely separate  
sets of servers (each address represents its own distributed set of  
servers) and there are already some small differences in behavior. The  
'DOI not found' and Handle not found' messages are one example. Future  
differences, probably through configuration, are possible.

At the moment there is nothing that constrains the handles resolved by  
dx.doi.org to be DOIs, but your TIB contact is correct in that the  
traffic levels are monitored and if a large number of non-DOIs go  
through dx.doi.org, then it is agreed that filtering will be added.  
The IDF pays for the running of those servers and it is reasonable  
that they would want that service to mainly be in support of their  
customers. At the moment there is so little cross traffic that it is  
not worth considering.

In general, it would be best to keep these apart in making static  
references. This would apply to the other handle-to-web proxies as  
well, e.g., hdl.loc.gov. They all resolve all handles right now, but  
they are intended to serve a specific a specific community, they may  
add their own special features over time, and none of them are  
promising to support all communities going forward.
