What is LTI?• A standard mechanism for seamlessly, but securely, connecting
learning applications and remote content to virtual learning environments (VLEs) and enterprise portals

Essential Ingredients• Connections configured using:
– launch URL– consumer key (to identify customer)– shared secret (to sign messages)
• Data shared:– user– context– role

How can LTI benefit me?

LTI Components• Messages:
– launch– content-item selection
• Services:– tool settings– outcomes 2 (public draft)– memberships (public draft)

So why bother with LTI?• Because it is “simply the best”!• Easier to implement than other standard solutions• No code needs to be added to VLEs• Solution works with (almost) every VLE• IMS-backed certification
![Page 13: Learning Tools Interoperability - Why the big deal? - Stephen Vickers | Talis Insight Europe 2016](https://reader036.vdocuments.mx/reader036/viewer/2022062522/587004d51a28ab427f8b5cc7/html5/thumbnails/13.jpg)

LTI 2, or Not LTI 2: that is the question!• LTI 2 brings YOU:
– a simpler, more secure way of registering tools– more control over what data you share with each partner– an extensible architecture allowing LTI security to be used for
bespoke messages and services with third parties
