[OAI-implementers] persistent IDs: DOI vs Handle

[Zeno Tajoli]

Hi,

>Any thoughts or advice on this process of choosing a persistent ID?
>Or, on the pros and cons of DOI vs the Handle System?

my 2 cents on the topic.
1) DOI vs Handle is not a real question. DOI is 'only' a particular 
application of Handle. For a sysop Handle and DOI are the same:
-you recive a dump code that need a central server to be resolved
-differences: Handle is free (now, but in the future ? ). For DOI you pay. 
But the 'DOI system' have much option (for example metadata on the central 
server not only in you server as Handle, etc.)

The real confrontation is : Handle/DOI vs OAI-identifier 
<http://www.openarchives.org/OAI/2.0/guidelines-oai-identifier.htm>.

Advantage of OAI-identifier:

-It is free now and for ever
-It is easier for Services Providers retrive metadata with OAI-identifier.
As example you can see ERRoLs 
<http://www.oclc.org/research/projects/oairesolver/default.htm>. This SP 
works better with OAI-identifiers
  than Handles. Remeber that now CrossRef gives free metadata from a DOI 
but in the future ?

Disadvantage of OAI-identifier:
-Data Providers must do more work. It is DP work to keep OAI-identifiers 
persistent
-The key point is: you select a web address (as http://eprints.rclis.org/), 
you need to mantain the same address (or a redirection).

Only my 2 cents.

Bye
