IMS Reusable Definition of Competency or Educational Objective


IMS Global Learning Consortium produced a specification with information model and bindings for Reusable Definition of Competency or Educational Objective in 2002. This influenced the IEEE LTSC Reusable Competency Definitions.

The "specification defines an information model for describing, referencing, and exchanging definitions of competencies, primarily in the context of online and distributed learning. In this specification, the word competency is used in a very general sense that includes skills, knowledge, tasks, and learning outcomes. This specification gives a way to formally represent the key characteristics of a competency, independent of its use in any particular context. It enables interoperability among learning systems that deal with competency information by providing a means for them to refer to common definitions with common meanings.

The core information in a Reusable Definition of Competency or Educational Objective (RDCEO) is an unstructured textual definition of the competency that can be referenced through a globally unique identifier. This information may be refined using a user-defined model of the structure of a competency." 

General information

The RDCEO has a very useful Best Practice and Implementation Guide that describes how it relates to other models and how it can be used in a range of contexts.

information to be gathered details
Name / title of source/model and version if applicable Reusable Definition of Competency or Educational Objective (RDCEO)
Stakeholder IMS Global Learning Consortium
Orientation A model and xml bindings for a single LOC. Can be used in any context but developed with education and training in mind.
Explicit / implicit Explicit
Organisational competence  
Number of people currently affected An international specification that has been around for 10 years but not sure how embedded it is in systems. May have been superseded by IEEE LTSC RCD.
User communities Developers of systems across a wide range educational sectors and countries.
Significant use cases  
Significant business cases  
Sample materials  
Key features influencing uptake A simple and extensible model with xml bindings and best practice available as well.

N Features ? notes
00 More than one model 0 As with IEEE-RCD, this deals just with the individual definition, not structures of them.
01 Identifiers 1 uri recommended
02 Hierarchy (internal) 0 RCDEO models a single LOC. Hierarchy could be provided using relationship metadata but this is not defined in the specification.
03 Internal relationships 0  
04 External relationships 0 Not explicitly but could be provided in metadata.
05 Conditionality / optionality 0  
06 Text syntax 0  
07 Structured identifiers 1 The same structure as IEEE LOM of an  <identifier> made up of <catalog> and <entry> as sub elements. No other structure defined.
08 Classification 0 Could be provided using relationship metadata but this is not defined in the specification.
09 Level attribution 0 Needs to be defined externally.
10 Level definition 0 Needs to be defined externally.
11 Context 0 Can be applied in any context.
12 Evidence and assessment 0  
13 Extensions 1 The schema allows for additional metadata to be added. This can be in any format.
14 Profiles 1 Profiles can be produced.
15 Adaptation 0  
16 Definition by example 0  
17 Learning resources 0  
18 Learner records 0  
19 Multilinguality 1 Uses Langstring
