IEEE RCD - Overview
The IEEE Reusable Competency Definitions (RCD) specification is a standard (IEEE 1484.20.1) issued by the Learning Technology Standards Committee of the IEEE Computer Society. It defines a data model for describing, referencing and sharing competency definitions, primarily in the context of online and distributed learning. IEEE RCD specify the mandatory and optional data elements that constitute a Competency Definition as used in a Learning Management System, or referenced in a Competency Profile.
The standard is needed because there are currently many definitions of the terms "Learning Objective", "Competency" and "Skill", and very little agreement between how those definitions can be used to define reusable data models. This standard uses a general definition that can be semantically "tightened" or "loosened" in the data itself, while conserving the same data model regardless of how strictly a particular organization or institution requires the data to be formulated.
The purpose of this standard is to define a universally acceptable Competency Definition model to allow the creation, exchange and reuse of Competency Definition in applications such as Learning Management Systems, Competency or Skill Gap Analysis, Learner and other Competency profiles,etc.
This standard also addresses the following needs:
- A common data model that allows the building of various competency models,hierarchies and maps (however, the definitions for such applications are outside the scope of this standard).
- A standard that allows persistent, long lived Competency Definitions to be created, exchanged among systems, and maintained.
- A standard method by which Competency Definitions can be identified as globally unique among compliant systems and repositories.
- A standard method to mark a superseded or obsolete Competency Definition,and to point to a more current Competency Definition.
- A common data model for the meta data that give a reusable Competency Definition its value in a reuse environment, such as the source of the Competency Definition, validation information, and other meta information useful to locate an objective in a repository or collection.
- Correspondence with the Learning Objects Metadata Standard developed by a parallel group.
|The IEEE RCD (IEEE 1484.20.1) standard defines an information model for describing, referencing, and exchanging definitions of competencies, primarily in the context of online and distributed learning. In this standard, the word competency is used in a very general sense that includes skills, knowledge, tasks, and learning outcomes. IEEE RCD provides a means to formally represent the key characteristics of a competency and to create common understandings of competencies that appear as part of a learning or career plan, as learning pre-requisites, or as learning outcomes. The identified information model provides unique references to descriptions of competencies or objectives for inclusion in other information models.
The RDC data model is minimal and extensible. It is neutral with regard to models of and uses of competencies. Competencies are defined and structured in many ways in different application domains. The standard allows implementers to share information according to the models they use. Semantics can be “tightened” or “loosened” in the data itself, while conserving the same data model regardless of how strictly a particular organization or institution requires the data to be formulated.
The data model contains the following mandatory elements:
- Identifier: A globally unique label that identifies the RCD. This identifier uses the same data elements as the identifier element defined in LOM (IEEE 1484.12.1) and consists of two subelements, Catalog and Entry. The identifier is sufficient to reference the competency in any system that stores or process the RCD.
- Title: A text label for the RCD. This label is a human-readable name. Although the identifier provides the definitive reference to the RCD, it is typically unintelligible. The title provides a convenient, readable alternative. The title may be repeated in multiple languages.
|The data model contains the following optional elements:
IEEE RCD specification
- Description: A human-readable description of the RCD. This unstructured character string is meant to be interpretable by humans only. The description may be repeated in multiple languages.
- Definition: A structured description that provides a more complete definition of the RCD than the free-form description expressed in the title and description, usually using attributes taken from a specific model of how a competency should be structured or defined. Typically, such models define a competency in terms of “statement, conditions, criteria,” “proficiency, criteria, indicators,” “standards, performance indicators, outcomes,” “abilities, basic skills, content, process,” and similar sets of statements.
- Metadata: Embedded metadata that also describe the RCD by, for example, identifying the author and publication date of the RCD or by specifying known relations to other RCDs.
