good question, Paul.

The IPT does have an embedded data cache and with every new version  
published it is first uploaded into the cache. At that moment  
potentially previously existing records, before being removed for  
performance reasons, are compared to new ones and it is thereby  
detected which records have changed, which were deleted and which are  
new. This information is in IPTs first version only accessible via the  
full dataset dump (aka darwin core archive), but it is planned to  
expose this also as a pageable atom feed and if requested by serious  
users, potentially also as OAI-PMH.
