We have three short videos to demonstrate features of the Data Capsule. 

Create and start a Data Capsule virtual machine. 

To be able to use Data Capsule, a user needs to first create a virtual machine in data capsule. The video below shows how to create a virtual machine in HTRC portal and start the VM. After the VM starts, the user is ready to use it by connecting via a VNC client such as Google VNC viewer. 

Operations in maintenance mode of data capsule.

By default, the data capsule virtual machine is in maintenance mode. In this mode, you are allowed to access any webpages or services but not the HTRC data services. Users can download and install software necessary for their analysis in maintenance mode. 

Operations in secure model of data capsule.

Users can switch to secure mode by performing operations in the portal. In secure mode, you are only allowed to access HTRC data services and all other webpages and services are blocked. The purpose of secure mode is to help scholars conduct non-consumptive analysis, and in this mode, users can only use HTRC data services and run analysis and they cannot export content of HathiTrust volumes. Therefore this is a secure virtual environment for non-consumptive research on HathiTrust digital library content.
