Search Service
Description
The OCF Collab competencies search service aims to make competency frameworks readily available to humans and machines by developing a membership trust network (Trust) 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.
The OCF Collab broadly defines 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 Collab defines 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, IMS Global’s CASE, Credential Engine’s CTDL-ASN, and University of Washington’s ASN. Since the OCF Collab 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 OCF Collab 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.

- Short Prototype Search Service Demonstration Video
- Search Prototype https://tool.ocf-collab.org/ - This is a prototype developed in 2020 that is limited to 300 frameworks, with 100 frameworks each coming from three registries using three different competency schemas: (1) Credential Engine Registry using CTDL-ASN, (2) IMS Global Case Network using CASE, and (3) Desire2Learn using ASN. A metamodel interchange API is used to translate between the schemas, so that each framework is available in its native schema or in both of the other two. These options are found via a download button located at the bottom, right of each competency framework detail page. The 300 frameworks are limited to four industries. To explore the prototype, use one of these keywords: manufacturing, industry, agriculture, or culinary. The search index for this prototype includes Competency statements, Competency Names, and Descriptions.
