Quantitative Data Mapping Guidance

Release 20220325
This page displays the Quantitative Data schema in an object-oriented format. Below you will find every class for this schema, each with a thorough description and a list of properties for that class. Where applicable, properties that leverage concept schemes (controlled vocabularies) will also show the available concepts for those schemes.
The purpose of this page is to make it easier for your team to map your schema and your data (your classes and properties) to the CTDL classes and properties.
For an RDF-centric view of this schema, use the Terms page.
This page exists for the following schemas:

The CTDL Quantitative Data schema (QData for short) is intended to describe aggregate/statistical data related to credentials and other such information. The QData model and accompanying properties and classes currently provide access to aggregate earnings, employment and holder data stemming largely from second party datasets (e.g., U.S. Department of Labor). Similar access is under development for including aggregate credential holder data. Current records in the Credential Engine Registry (CER) embody authoritative data provided either by: (1) the credential organization that owns or offers the credential as well as any associated learning opportunities or assessments; or, (2) a second party under the authority of such a credential organization. The earnings, employment and holder information of concern here is largely sourced through second party data aggregators including public sector agencies at both state and federal levels and private sector organizations supporting specific services and making that data more-or-less publicly available through various means.

The CTID is the equivalent of a version identifier for the resource. Different versions of a resource are considered distinct expressions and each must be assigned its own CTID. Each version of a resource can have only one CTID assigned. However, a single version of a resource may have distinct identifier values for both the ctid property and the credentialId property. In such a case both identifiers will be recognized by the resource creator/owner/provider in transactions with the external environment.
