Identifiers have clear and consistent parts.
This similar to Text syntax. URIs can often show these patterns. Or subject and level information might be shown: M2.25 could represent mathematics level 2 item 25.
It is important to know if this implicit information is also available as part of the model properties or if users need to know the code before effectively using the LOCs.
- The e-Competence Framework has the identifiers of competences structured according to the following pattern: competence_area.competence. The competence area is a single capital letter from A to E; the competence in that area is a number from 1 upwards. Currently the highest number used is 10.
- On the other hand, the ASN explicitly excludes structure in identifiers, stating that their identifiers are opaque.
It is very clear that there is no standard way of structuring an identifier in the field of competence or learning outcome. In any case, the possible structure of identifiers is not within the scope of standardisation of competence representations.
InLOC does not model structure of identifiers in any way.
