The presence of sites which are dceeribsd as LTI App Stores raises in my mind the question of whether there is a commonly agreed definition of what an LTI App is. I am not sure this is the case.For me, an LTI App (or LTI Tool Provider) is characterised by:1. The Tool Provider issues a unique key and secret to each LTI Tool Consumer to enable access.2. The Tool Provider has an endpoint which is capable of receiving and validating LTI launch requests.3. The response made by the Tool Provider would vary according to the context/resource link/user/role data provided in the launch request.The nature of the web application provided by the tool provider does not matter; it may deliver content, an activity, or something else. It does not have to be IMS certified or even capable of being IMS certified (since certification places additional expectations on tool providers).Some of the apps on the Edu Apps site fit within this defintiion, but taking the YouTube app as an example, I am not convinced all do. Does the connection to YouTube require a unique consumer key and secret? Are these issued by YouTube? Does YouTube accept LTI launch requests? Is context/resource link/user/role data being passed to YouTube? Does the response from the launch request change according to the data being passed? If not, what does this site mean by an app built on LTI ? http://lorqoizce.com [url=http://ndrezbs.com]ndrezbs[/url] [link=http://plzggps.com]plzggps[/link] No copmlaints on this end, simply a good piece. http://smyqvtfemyb.com [url=http://cpilcyxggp.com]cpilcyxggp[/url] [link=http://zlofvxmrhn.com]zlofvxmrhn[/link]
