Credential Engine Technical Services

Last Updated on 8/3/2020


The Credential Transparency Description Language (CTDL) family of specifications, our account management system, publishing tools, and Credential Registry are and will always be available at no cost. To enable a broader community of practitioners and providers to leverage these, we offer related fee-based technical design and development services.

We specialize in helping organizations define, implement, and derive value from general open data strategies as well as from the Credential Registry and other Credential Engine services. Our areas of focus include credentials, skills and competencies, education and career pathways, transfer value, and quality assurance.

Our services team, which includes the Credential Engine and our strategic partners, has deep expertise with partner engagement in all phases of project design through implementation project management, data modeling and design, schema development and mapping, data publishing, datastore infrastructure, and integration. Examples of our services program with combined capabilities are listed below.

Please contact our Chief Technology Services Officer or use our general contact form for more information about how our team engages with partners on projects, services and capabilities, and to develop project scope requests.

Project Management

We develop requirements documentation, and utilize tools for managing design and development processes. We lead, facilitate, and manage projects.

Project Coordination and Management
Coordinating meetings and scrums, getting input and feedback, and handling documentation.
Process Workflow Design
Determining and documenting business process workflows that require data.
Project Requirements and Specifications
Documenting functional requirements and data specifications.
Pilot Project Management
Designing, initiating, and documenting prototype testing.

Data Design

We develop and maintain the Credential Transparency Description Language (CTDL) schemas and provide data design services.

Use Case Development
Developing and analyzing use cases for data modeling and design.
Data Modeling and Schema Design
Iterating diagrams to create domain models and related schema classes, properties, and concept schemes.
JSON-LD Encoding Examples
Encoding sample data to validate schema design.
Schema Mapping
Creating schema mappings between data definitions or data standards to determine matches and weight of alignment.
Schema Management
Implementing policy and tools for instantiating and managing open schemas modeled on Semantic Web specifications.

Linked Open Data Infrastructure

The team specializes in open technologies to support Linked Open Data (LOD) infrastructure. We design and maintain all of the Credential Engine’s cloud-hosted technologies, including: data publishing tools, the Credential Registry, and Registry data consuming services.

Publishing APIs
Support for utilizing our APIs for mapping from structured data sources to a common language (schema) and for outputting JSON-LD encoded metadata.
Publishing Interfaces
Interfaces (e.g., bulk upload and manual entry, ingesting) for managing and converting information to a schema and for outputting JSON-LD encoded metadata.
Publishing System
System for authentication, role and information management, activity logging, and reports.
Linked Data Registry
Datastore solution for maintaining, archiving, and versioning JSON-LD data and supporting shared and private data communities.
Graph Search
Handle graph, relational and hybrid database solutions.

Application Layer Support

The Credential Registry also supports an applications marketplace by making data available for consuming and supporting partners who build applications and tools that use Registry data. The Credential Finder and its search widgets use a combination of direct Registry searching and bulk downloading. The data from the Registry is valuable to support a wide range of use cases such as training AI, aligning skills and competencies, recommending credentials and pathways.

Consuming Credential Registry Data
Development of specialized searches and imports for systems and applications to consume data from the Credential Registry.
Embedding CTDL Schema on Webpages
Customized outputs from the Registry for embedding on websites for search engines.
Data Integration
Technical assistance to support data integrations using credential, competency, and related data.
Application Hosting
We utilize Amazon Web Services and Azure cloud hosting services for development, staging, and production environments.
Applications of AI
Our strategic partners design and develop AI applications including Natural Language Processing that utilizes Linked Open Data as well as other data sources.
We offer customizable embeddable search widgets that leverage the infrastructure of the Credential Finder.

The Credential Engine Team and Strategic Partners

The Credential Engine technical team works side-by-side with our strategic partners long enough that we work collaboratively as a distributed team with clear and complementary roles.

Our technical team started working together over a decade ago. We design, develop and maintain all of the Credential Engine technologies in collaboration with our strategic partners listed below. You can see our work via the Credential Engine’s specifications and open technology guides that we maintain on our technical site.
