[OAI-implementers] resumptionToken Implementation

[Jose Blanco]

Jeff,

What I did, and have seen that others have done also, is basically encode
the resumption token in a way that next time your oai data provider is
called you know where to start extracting records (I'm talking specifically
about ListRecords, but the idea works for ListIdentifiers, and even
ListSets)

For example, your resumption token could take on a value encode in the
following way:

Expirationg_date,start_date_stamp_date,end_date_stamp_date,metadata_format,s
et,database_being_used,number_of_records_returned,

You basically want your resumptionToken value to communicate where to resume
harvesting, so you want to give it the values your repository will need.

Hope this helps.

Jose

I am trying to get some kind of idea how people have implemented the 
resumptionToken. Would some of you be so kind as to share some details 
on how you implemented it?

It would be greatly appreciated.
