OneRoster® Background


The OneRoster® standard is a subset of the Learning Information Services standard that focuses on the school’s needs to exchange roster information and grades. The standard includes both SOAP and REST-based bindings to make it quicker and easier to implement the exchange of information about people, membership, courses and outcomes. In addition to the standard, OneRoster™ includes a format for CSV files that are typically exchanged between the school and the vendor to populate the roster information needed to gain access to learning tools, portals and learning environments.

Feedback on the specification is welcomed in our public forums.

Learning Information Services Background


The Learning Information Services (LIS) specification is the definition of how systems manage the exchange of information that describes people, groups, memberships, courses and outcomes within the context of learning. The LIS v2.x specification supersedes the IMS GLC Enterprise Services v1.0 specification. The LIS specification is based upon the aggregation of the Person Management, Group Management, Membership Management, Course Management, Outcomes Management and the Bulk Data Exchange Management Services specifications. The LIS v2.0 can be implemented using both a Web Services infrastructure (based upon a SOAP http transport mechanism) and the Lightweight Directory Access Protocol (LDAP). An implementation is not required to support each and every service. Neither is an implementation required to support each and every operation. Interoperability is best defined through the use of a Domain Profile. This specification includes such a profile for Higher Education. Interoperability is supported between systems that implement the same profile. The LIS documentation consists of:

  • The LIS Specification - describes how the LIS is composed using its six component services;
  • Information Models - these documents contain the normative description of the various service definitions, data structures and their relationships. Each of the six services has its own Information Model;
  • Binding documents - each of the Information models has an associated WSDL binding document. Some of the services also have an LDAP binding document;
  • Best Practice & Implementation Guide - this is intended to provide vendors with an overall understanding of the IMS GLC LIS Specification, the relationship of the specification with other IMS GLC specifications, and a best practices guide derived from experiences of those using the specification. The guide also includes a several actual examples that describe how vendors can make the best use of the IMS LIS Specification;
  • Core Profiles & Conformance Specification - a set of profiles of the LIS specification has been created. The Core Profiles identify the minimal subset of the functionality that must be supported by systems developed for deployment in HE. These Profiles (there is a Core plus several Additions) define the set of operations and data models that must be supported by the systems supporting the set of services within the LIS. Each profile contains its Conformance Specification against which compliant systems are tested;
  • The Binding Files - one of the outputs of the LIS specification is the set of Web Services Description Language/XML Schema Definition (WSDL/XSD) binding files. Each service has its own set of WSDL/XSD files. It is these files that are used by code-generation tools to create the source code that handles the SOAP messages and XML data structures. Some small changes are required to the WSDL files to map the SOAP messages to the actual server-based implementation of the Web Service. Each of the services has a set of vocabulary files that contain the set of default vocabularies defined in the Information Model. The vocabulary files are instances of the IMS GLC Vocabulary Data Exchange (VDEX) specification.

Feedback may be posted in the IMS public forums.

IMS Learning Information Services Specification - Version 2.0.1 Final Specification (30 September 2013)

The Learning Information Services v2.0.1 corrects some minor errors in the v2.0 specification and updates the Core Profile definition. The specification document set contains information models, binding documents, best practice and implementation guidance, profile and conformance specification, and supporting files.
