1 IMS Standards in Ac:on Colin Smythe (IMS Chief Architect) 1 From the Specifica:on to Adop:on The aim is improve learning Crea:ng an interoperability specifica:on is only part of the solu:on IMS must simplify and accelerate adop:on of a specifica:on IMS has a significant legacy (15 years +) and so backwards/forwards compa:bility are issues 2 1

3 IMS Specifica:on Ar:facts The Specifica:on Documenta:on Conformance Test Systems Reference Test Sets Reference Implementa:ons Code-level APIs and API Documenta:on Tiered and mul:-specifica:on enabled APIs 5 Data Defini:on Specifica:ons A specifica:on where IMS define the data formats in which the informa:on is to be exchanged i.e. NOT HOW the data exchange takes place Typical data defini:on specifica:ons are: Common Cartridge & Thin Common Cartridge Ques:on & Test Interoperability (QTI) OpenVideo (new and to be released early 2017) 6 3

4 Data Valida:on (CC & QTI) Validation for data specifications such as Common Cartridges (CC), Question & Test Interoperability (QTI), etc. located at: 7 Ques:on & Test Interoperability QTI 1.0 released in May 2000 QTI 2.2 released in September 2015 Several Profiles produced for specific member-community needs Experimen:ng with a new 3 rd Genera:on QTI, called aqti, based on Web-components Adopt QTI

5 Member Validators Note the Profile-specific validators. 9 Service Defini:on Specifica:ons A specifica:on where IMS define the data formats and how the informa:on is to be exchanged Typical data defini:on specifica:ons are: Learning Tools Interoperability (LTI) OneRoster Caliper Competency Services (new, to be released early 2017) 10 5

6 OneRoster Specifica:on Support informa:on exchange between a Student Informa:on System (SIS) and a Learning Management System (LMS) Will be supplying wide range of APIs (ORCA) based upon the OpenAPI Specifica:on Conformance is available for: CSV Import/Export Service Provider (REST/JSON) Service Consumer (REST/API) 11? OneRoster-based Systems System (LMS, SIS, Assessment, etc) OneRoster Web Services? CSV Files (Import/Export) CSV Files (Import/Export) 6

7 25/08/16 OneRoster 1.0 Conformance Testing System for a Service Consumer/Client is located at: 13 Service Consumer testing requires the Implementation Under Test (IUT) to send a set of OneRoster HTTP messages to the IMS OneRoster Conformance Test System. This requires the IUT to use the supplied unique Consumer Key/Secret for authentication. 14 7

8 25/08/16 The Test System displays which tests have been run, failed or passed. 15 The Test System displays which tests have been run, failed or passed. Here the system has passed ALL of the tests and thus Certification. 16 8

12 A summary of the results before the testing has begun i.e. before messages from the Sensor under test have been sent to the Caliper Conformance Test System. Note that NOT ALL of the actions are required to obtain certification i.e. only those marked with an *. 23 This report shows that the Sensor under test will be certified as supporting the following Metric Profiles: Assessment AssessmentItem Annotation Assignable A summary of the results during testing i.e. messages from the Sensor under test have been sent to the Caliper Conformance Test System

13 The test system provides a log of the messages received from the Sensor under test. Here is the payload for the Bookmarked action of the AnnotationEvent. 25 Applica:on Sensor Instrumenta:on Instrumentation is where you must use the Sensor API s object-oriented interface to drive the event notification i.e. insert the Sensor calls at various points in you App/System/Tool.
