Viral Evangelism

• March 2008, I had a Google Summer of Code in-flight for Sakai and Moodle

• So I invented a non-specification that was a bit of Wimba and a bit of Blackboard - I called it Simple LTI and promised it would be "temporary"

• Marc Alier (Moodle committer) made the "Dinosaur Video"

Purpose of Certification

• Assure the end-user/purchaser that products will interoperate

• Any certified Provider (Tool) should be able to interoperate with any certified Consumer (LMS)

LTI + SCORM.com = Win!

• Customers win because they don't have to connect the SCORM runtime directly to their LMS

• SCORM.com wins because they can quickly integrate (with outcomes) to all of the certified LMS's


WikiSpaces.com and LTI

• Free public Wiki – 6 million accounts

• Business model – "Private Label Spaces"– One "space" per school or district

• Each Space can have many "Wikis"– One per class (approximately)

• Data and accounts are isolated

IDEA: LMS As Tool Provider..

• Imagine a teacher that needs a feature from another LMS.

• They could add a link from their LMS to an LMS in the cloud that they actually like


LMS as Tool Provider

• Sakai 2.8– Exports Tool Instances– Trusted Mode: OAE Hybrid or Portal / CLE

• Moodle 2.x Module – Juan Levya – Exports Course or Tool– Can use to merge students into instance

• Blackboard 9.1– Prototype Building Block

LTI 1.0 and IMS Common Cartridge 1.1

• Common Cartridge 1.1 includes the ability to define a Basic LTI resource and include that resource in course organizational structures

LTI 1.1 Outcomes

Mentor RoleIMS LTI 1.1.1


Mentor Role

• Driven by NYC DOE – “Parent”

• Important K12 use case

• I am the parent of user 45, 5039, and

2341


role_scope_mentor=f5b2cc6cac504dff,dc192c-b0fe-68b8-16e

A comma separated list of the user_id values which the current user can access as a mentor. The typical use case for this parameter is where the Mentor role represents a parent, guardian or auditor. It may be used in different ways by each TP, but the general expectation is that the mentor will be provided with access to tracking and summary information, but not necessarily the user’s personal content or assignment submissions. In order to accommodate user_id values which contain a comma, each user_id should be percent-encoded to ensure that at least commas and percentage signs are replaced (with “%2C”, or “%2c”, and “%25” respectively). This also means that each user_id from the comma separated list should percent-decoded before a TP uses it. This parameter is optional and should only be used when one of the roles passed for the current user is for urn:lti:role:ims/lis/Mentor.


BLTI Extensions


Best Practice Document Means:

• Not an approved specification– Not publically released – members only - Alliance

• No certification is provided• Test harness supports extensions as an Easter Egg


Important Disclaimer...

Basic LTI Extensions are not a formal standard – they is only an engineering exercise to explore use cases and applications of the IMS Learning Information Services in an IMS Basic Learning Tools Interoperability environment. Since Basic LTI Extensions are not a standard, it is not appropriate to publically claim compliance to it.


Basic LTI Extension Point


Service Extensions

• Return Outcome (i.e. grade)– LTI 1.1 is better – deprecated

• Memberships (i.e. Roster) Retrieval

• Settings Service (playlist stored in the LMS)


Implementations of Extensions

• Complete and Available– Sakai – Full Support released in 2.8

– Moodle – Module 1.9 / Module 2.0

– ATutor 2.0.2

– Vickers Building Blocks

• Anticipating / Hope– Instrcuture


Planned Documentation

• I will write some CC0 documentation for the extensions in the context of Sakai

• I will build sample PHP code to talk to these extensions in the content of Sakai


IMS LTI 2.0


IMS LTI 2.0

• Transition to resource oriented models

for services with RDF/REST Bindings

• Tool registration – Great increase in

convenience and support for App Store

use cases


LTI 2.x Roadmap

• LTI 2.0 was reduced in scope to registration and launch

• LTI 2.1, 2.2... Will come in quick succession after 2.0 is done – drafts in great shape

• Most vendors will end up implementing 2.1


JSON-LD – www.json-ld.org

• RDF / Linked-Data meets Hacker-Friendly JSON

• Depending on the application, you can look at it as a collection of linked triples or just a clean serialization of a REST-Style resource


lti_message_type=basic-lti-launch-request | ToolProxyDeploymentRequest | ToolProxyReregistrationRequestThis indicates the type of the message. This allows a TP to accept a number of different LTI message types at the same endpoint (a.k.a. handler).

....


Hoped for Scope for 2.1

• Much Broader Grade Services• Better Common Cartridge Interaction– Two layers of abstraction – kind od like mime-type


Building some LTI 2.0 code

• We are building code in the next few months• “Hello World” in more languages at the

beginning– Java, PHP, .NET, Python, Ruby...

• Will use these to cross-test implementations• Will focus on completing the set of these

*before* we build certification


LTI 2.0 Certification

• Actually built prototype certification code Fall 2011 that implemented “LTI 1.2” tool registration

• It was in PHP and not too hard• Left it fallow at the LTI 1.1 / 2.0 split• Will not be hard to pick back up and build 2.0

certification


Developer Support from IMS

• Test Harnesses• Sample Code• Recorded Presentations• Certification• Staff help for IMS Members

http://www.imsglobal.org/developers/LTI/test/v1p1/


Summary

• LTI 1.0 – Basic Launch• CC 1.1 – Cartridge of links• LTI 1.1 - grade return• LTI 1.1.1 – Mentor role• LTI 2.0 – Registration• LTI 2.1 – Grade + Super-CC
