[MOBY-dev] Handling of different LSIDs if the services are equal

[Andreas Groscurth]

Hi everybody,

I have the following situation:

I have two local repositories. One is used as my central repository, the other 
one as a secondary repository. My central repository was updated via my 
syncronisation procedure from the BioMoby central and the secondary 
repository was initialised with the database dumps from BioMoby.

I found out that the LSID of a service is changed or updated if a service is 
registered at a central, so now I have the situation that if I run the update 
mechanism for the secondary repository, that services may have different 
LSIDs (because of an update of the central rep.), but the services are equal.

In my application I check whether the LSDIs have changed and if so, I call the 
RDFagent to apply the changes. The agent by itself calls a internal 
comparison method to check if the services are different or equal. 

So my question is how to handle services with different LSIDs which are 
actually equal, which means, where the LSID has only changed due to local 
registration ?

One possibility could be not to compare the LSID but to use the comparasion 
method as it is used in the RDFagent. 

Another thought is, if two services differ only in the LSID, but are actually 
equal, shall the 'older' service just get the LSID from the younger one ?

Thanks for your input
Andreas
