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)

SCORM Runtime


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

Mentor Role
IMS 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 |
ToolProxyReregistrationRequest
This 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
