How to Read These Tables

This page displays the Credential Engine Meta Schema schema in an RDF-centric format. Below you will find every class, property, concept scheme, and concept for this schema, each with a thorough description and connections to other terms. For an object-oriented view of this schema, use the Mapping Guidance page.

The following tables use a common set of attributes to describe each Term. Not all terms will have all attributes.

URIUnique Resource Identifier used to identify the term. It consists of a full namespace (such as followed by the term itself. This URI can uniquely identify the term in various contexts, including those where multiple namespaces are used.
Shorthand URIEquivalent to the URI, but using a shorter namespace prefix (such as meta) followed by : and then by the term itself. Use the References table to determine which prefix is associated with which full URI namespace.
LabelA human-readable label assigned to the term. In applications, this may be substituted for any label that is suitable for that application. May be represented in multiple languages.
DefinitionThe normative definition for the term. The definition field controls the true meaning of the term regardless of its URI or its Label. May be represented in multiple languages.
CommentAdditional non-normative descriptive text to aid in understanding the intended meaning and/or purpose of the term. May be represented in multiple languages.
Usage NoteAdditional non-normative descriptive text to aid in understanding the intended usage of the term. May be represented in multiple languages.
Type of TermIndicates the type of term: Class, Property, Concept Scheme, or Concept.
StatusIndicates the current status of the term: Stable, Unstable, Pending, or Deprecated.
Subclass OfIndicates that this class is a more narrowly-focused variant of the referenced class.
Subproperty OfIndicates that this property is a more narrowly-focused variant of the referenced property.
Subconcept OfIndicates that this concept is a more narrowly-focused variant of the referenced concept.
Equivalent ToLists the terms, often from other namespaces, that have the same (or nearly the same) semantic meaning as this term.
PropertiesLists the properties that belong to this class (as defined by the properties' "Domain Includes" data).
In Range OfLists the properties whose value may be an instance of this class (as defined by the properties' "Range Includes" data).
Domain IncludesLists the classes to which this property belongs.
Range IncludesLists the classes or value types that may be used as a value for this property.
CER Target SchemeLists the concept schemes that are intended to ultimately be used as values for this term, either directly or indirectly.
ConceptsLists the terms that may be considered concepts for this concept scheme.
CER Scheme ForLists the terms that are intended to reference terms from this scheme, either directly or indirectly.
In SchemeLists the concept schemes in which this concept appears.
SerializationProvides links to serializations (in JSON-LD and Turtle) for this term.
HistoryProvides links to the schema update history for this term.

Use the options below to determine the totals to include for the selected schemas. For each schema, you can also opt to include counts for terms that that schema borrows:

  • From other Credential Engine schemas (e.g., CTDL-ASN borrows ceterms:industryType from CTDL for its ceasn:CompetencyFramework class)
  • From non-Credential Engine schemas (e.g., CTDL borrows schema:QuantitativeData from for its ceterms:financialAssistanceValue property)

Terms will not be counted twice regardless of which combination of options you select.
