Reflection on Dr. Severance's Presentation

I think I got only the key points of Severance's presentation - IMS: Learning Tools Interoperability (Severance, Feb. 25, 2013).

1. An open protocol for data sharing will save consumers lots of money.
2. LTI (Learning Tools Interoperability) allows LMS to own authentic data such as student ID in local server while saving the non-authentic data in a public server. In this way, the data retrieving becomes independent from LMS and improves the chances for data interoperability. 

If learning analytics want to be applied to multiple learning system - LMS, CMS, social media -, it would be important to have a commonly accepted LTI. However, learning from the experience of SCORM which has been not very successful, IMS LTI might have a long way to go before widely adopted in the field.
