Hi Josh
If your data is not on the same Indicia warehouse as IRecord then the two warehouses would need some data exchange system to be set up so that they can talk to one another. I don't think this has been tried yet but I know a lot of work has been done on setting up an exchange with BTO and their system.
I'm not sure this is relevant in your case though so don't sweat.
When you say you have 'signed a sharing agreement' that is nothing like what I was talking about which was clicking a couple of checkboxes in the warehouse interface. If what you were signing was an agreement about using the Indicia warehouse that the Biological Records Centre provide then that will be the same warehouse that IRecord uses. In that case, the documentation I linked to previously should help to explain.
