Those look like Sync Services properties. Sync Services was a way of synchronizing data between applications and computers back in the days when PCs were still peoples' digital hubs. In Leopard (I think) Apple added the option to directly sync a CoreData database with Sync Services, greatly simplifying the sync client logic you'd normally have to write to sync data with Sync Services. Sync Services was deprecated in favor of iCloud in Lion. Anyway, you can ignore these properties if your project doesn't use Sync Services.
