# TLA Standards

  • cmi5: The cmi5 Specification (opens new window) is an e-learning specification intended to take advantage of xAPI as a communications protocol and data model while providing definition for necessary components for system interoperability such as packaging, launch, credential handshake, and consistent information model. Any activity providers that intend to affect the TLA Reference Implementation should send cmi5 compliant xAPI statements to the Transactional LRS. To learn more about cmi5, please read the specification on GitHub.

  • ELR: The IEEE Enterprise Learner Record standard just received approval from the IEEE Learning Technology Standards Committee (LTSC) and a study group has been formed to develop this standard. The draft data model for this standard supports a ledger of all learning activities a learner interacts with across a career. The data model includes data about competencies, credentials, activities, and relevant job information for each learner. It provides links to evidentiary chains, and establishes linkages to career field management tools used in human resourcing, talent management, and other personnel management systems.

  • LAM: The IEEE P2881 Learning Activity Metadata (opens new window) standard is being developed through an active IEEE study group. The ADL Initiative has created a draft data model for this standard that builds on the IEEE 1484.12.1 LOM standard to include more detailed descriptions of an organization's training and education assets.

  • RCD: The IEEE 1484.20.1 Reusable Competency Definition standard (opens new window) is still being developed. It provides a common method for describing competencies, establishing their relationship within a framework of other competencies, and defining the evaluation and assessment criteria for evaluating individual or team proficiency.

  • xAPI: The Experience API standard (opens new window) is an interoperability specification for learning technologies that describes communication about learner performance.

# TLA Components

  • CaSS: The Competency and Skills System (opens new window) is the CMS currently used within the TLA Reference Implementation. CaSS is used in the TLA Reference Implementation as a Competency Registry that maintains Competency Frameworks and their related competency definitions. CaSS is also used to evaluate learner evidence and update learner records based on that evidence. CaSS Authoring Tools allow organizations to import, update, or create competency definitions and competency frameworks.

  • KAFKA: Apache Kafka (opens new window) is the gateway to the TLA's core systems. Kafka is an open source streaming service that forwards different TLA data topics into their respective databases. TLA components use microservices to subscribe to different data topics or to publish their results. For example, all TLA MOM statements are forwarded to different data streams (i.e., learner-data, resolved, or authority).

  • KeyCloak: Keycloak (opens new window) is an open source Single Sign On (SSO) service currently used by the TLA Reference Implementation.

  • Moodle: The Moodle (opens new window) Learning Management System (LMS) is used to deliver online courses.
