ID in URL

Hi Sascha,
We've been using and loving Open Content for large numbers of items, and sometimes we have to make our changes to the JSON in the "Edit Raw Data" option when there are lots of sweeping changes. However, when we do this, it seems that the OpenContent module assigns new IDs to all of the items, and this changes the URLs to those items, which means that all the links break.
Is there any way to prevent this from happening, either by hiding the ID from the URL or somehow keeping it from changing?
Thanks,
Mick
