BACKGROUND: The Library of Congress (LOC) Linked Data Service (LDS) has become the premier Linked Data service for the bibliographic community. With a focus on catering to machine-to-machine communication, its services have been integrated into a variety of library software in the community and developers make heavy use of the service on a daily basis. Its web interface has become equally popular by library professionals, especially catalogers. LDS is a Linked Data application, meaning it makes data available via well-defined and predictable interaction patterns and uses the Resource Description Framework (RDF) data model. It features, additionally, a number of well-defined Application Programming Interfaces (APIs).

A typical test invokes an HTTP endpoint using a GET request, with or without special parameters, and evaluates the results, both the HTTP headers returned and response body. LDS includes hundreds of tests designed to ensure the service inputs and outputs match expectations and requirements. These are implemented in an aging framework and are invoked manually. The Library needs to migrate these tests from this framework in such a way that they can be integrated into CI/CD (Continuous integration/continuous development) pipelines.

The Library does not have sufficient staff with the specialized expertise to carry out this task. That expertise is a combination of in-depth knowledge of Resource Description Framework (RDF), including the various software options used to work with RDF, and programming strategies for optimal CI/CD integration.

SCOPE: The Contractor shall design and code a system for testing the expected inputs and outputs of LDS and migrate the existing tests. The Contractor shall use a strategy that makes the addition of new tests and modifications to existing ones straightforward and with minimal involvement of library staff as users of the system. Tests are added by Library staff regularly and should not be a laborious process.

The final deliverable for this contract would be a set of programs with attendant documentation, which can be used by the Library for automated testing of the inputs and outputs of the Library’s Linked Data Service.
