When you’re working with Sharepoint workspace you might notice that you can create several instances in an meeting-workspace – one for each appointment.
Depending on the template you choose for your workspace, you can upload documents to a document-library in your workspace. These are manage individually for each appointment (aka instance).
Even though it seems as if there would be an individual document library per instance, this isn’t the case. Instead there is only one document library, which is being “filtered” according to the currently visible instance.
To get the content of all instance, all you have to do is to append &InstanceID=ALL
to the URL of the list (or document library) and off you go!
