Unique identifiers enable industries to help people identify, describe, and compare specific offerings. Examples of industry agreements about useful unique identifiers include UPC codes for retail products, URLs for webpages, ISBNs for books, GPS coordinates for locations, and MLS numbers for real estate listings.
Credential Transparency Identifiers (CTIDs) bring the benefits of unique identifiers to credentialing ecosystems. CTIDs allow credentials and their associated information to be distinguished, thoroughly described, and widely recognized through effective data management practices.
A CTID is a globally unique identifier associated with a specific credential or credential-related resource. The Credential Transparency Description Language (CTDL) defines 69 different types of resources utilizing CTIDs, including credentials, programs, courses, organizations, competencies, and more. These clearly defined types of resources can be expanded as CTDL expands to address the needs of credentialing ecosystems.
Each CTID is made up of a standard UUID prefixed with “ce-”. For example, the CTID for Ivy Tech Community College’s Associate Degree in Cyber Security Information Assurance is “ce-48b8cad7-2c58-4a9c-b46a-74caa362d30b”. This unique format ensures that no two CTIDs have the same value, enabling systems to easily identify specific resources and exchange data reliably.
Applications use CTIDs to help people access credential information across multiple systems and platforms. This makes it convenient for individuals to engage with credentialing ecosystems, regardless of where the information is stored. To ensure precise tracking and comprehensive descriptions of CTDL data, it is essential for databases to store CTIDs for the purpose of publishing and/or consuming CTDL data.
The Credential Registry serves as one connection point for data using CTIDs. Information associated with any CTID published to the Credential Registry can be accessed directly by appending the CTID to URLs. For example,
These links can be embedded in various systems and applications to ensure that clearly identified credential information is integrated across a variety of applications, including across multiple organizations, such as career exploration tools, marketing platforms, curriculum management tools, longitudinal data systems, transfer systems, college catalogs, and digital credentialing tools, as well as within Learning and Employment Records issued to individuals.
Considering the substantial size of the credentialing market, the growing demand for reliable, transparent credential information, the wide array of stakeholders seeking such information, and the pivotal role credential information plays in numerous consequential decisions, Credential Engine strongly recommends that credential data managers integrate CTIDs into their source data systems.
