OCN: Competency Explorer

From T3 Network Wiki

>> OC Network Home >> TAW >> Competency Explorer

The Open Competencies Network (OCN) Competency Explorer, aims to make competency frameworks readily available to humans and machines by developing a membership trust network of open registries holding one or more competency frameworks and by enabling search and retrieval of those frameworks and their competencies from any registry node in the network regardless of the technical standard used to express the competency data.

The OCN broadly takes the concept of a competency to include any attribute required to perform a work role including knowledge, skills, abilities, dispositions, tasks, and habits of mind. The Network understands a competency framework (Asset) as an instance of a logically related set of competencies based on a specific competency framework model that has been encoded using a recognized metamodel standard such as, but not limited to, 1edTech’s (IMS) CASE, Credential Engine’s CTDL-ASN, and University of Washington’s ASN. Since the Competency Explorer standard does not require a registry to natively use any particular metamodel, it relies on a transformation, or interchange service to transform instance data following one metamodel into instance data following a different metamodel. In the Competency Explorer instance based on this specification, the transformation service used is Rosetta Lenssm by Eduworkstm.

The Network infrastructure has formal mechanisms of trust that protect the integrity and rights of registry owners and competency framework contributors by promoting practices that honor constraints on access, use and retention of retrieved competency frameworks and competencies.

Competency Explorer Enhancement Project

  • Competency Explorer Use Case Analysis: Use cases from requirements working group (RWSC) analysed to elicit the technical features that would be required for each use case.
  • Competency Explorer Feature Analysis: The features required for all the use cases listed with details such as which use cases they fulfil.
  • Competency Explorer Project Plan (Project Plan Number: OCFC: PP-002) describes the project analyse and implement where possible the features required for the proposed use cases.
  • Search technology demonstrator https://tool.ocf-collab.org/ - This is a staging server used during the development project, that means it is used for testing and is not "production quality". In particular it does not have a full complement of data and its functionality will vary and occasionally fail. As it is a technology demonstrator less attention has been paid to user interface and user experience than would be necessary in production-level search and exploration node; it demonstrates the data that is available and the searches that can be built on that data, the architecture of the Competency Explorer is such that each node would be able to implement user interfaces that met their own requirements.
