** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** MODERN BREEDING METHODS RELY ON LARGE AMOUNTS OF PHENOTYPIC AND GENOMIC DATA COLLECTED ACROSS YEARS AND ENVIRONMENTAL CONDITIONS. THIS PRESENTS NEW CHALLENGES IN EFFECTIVE DATA MANAGEMENT AND INTEGRATION. WITH RECENT ADVANCES IN AUTOMATION AND GENOTYPING METHODS, THE SIZE AND COMPLEXITY OF DATASETS HAVE INCREASED SIGNIFICANTLY, OFTEN RESULTING IN DATA BEING STORED ON MULTIPLE SYSTEMS. DIGITAL AGRICULTURE AND MODERN PLANT BREEDING APPROACHES INCREASINGLY REQUIRE AGGREGATION OF DATASETS FROM DIVERSE SOURCES, NECESSITATING DATA EXCHANGE BETWEEN DISPARATE SYSTEMS. TO FACILITATE INTEROPERABILITY AMONG BREEDING APPLICATIONS, THE BREEDING APPLICATION PROGRAMMING INTERFACE (BRAPI) WAS DEVELOPED. BRAPI IS A STANDARDIZED SPECIFICATION FOR RESTFUL WEB SERVICE APPLICATION PROGRAMMING INTERFACES (APIS) IN THE PLANT BREEDING DOMAIN. INITIAL VERSIONS OF BRAPI HAVE HAD A SIGNIFICANT IMPACT ON DATA ACCESSIBILITY AND USABILITY ACROSS MAJOR BREEDING APPLICATIONS. HOWEVER, THE SPECIFICATION NEEDS TO CONTINUE TO GROW AND EVOLVE TO REMAIN RELEVANT AS NEW HIGH-THROUGHPUT PHENOTYPING AND SEQUENCING TECHNOLOGIES BECOME MAINSTREAM IN BREEDING. DEVELOPMENT AND MAINTENANCE OF SUCH A STANDARD IS RECOGNIZED AS CRITICAL TO SEVERAL IMPORTANT LARGE BREEDING SYSTEM INITIATIVES AS A FOUNDATIONAL TECHNOLOGY. THIS PROPOSAL INTENDS TO BUILD UPON THE FOUNDATIONS OF THE BRAPI STANDARD AND CONTINUE TO DEVELOP THE BRAPI PROJECT. TO ACHIEVE THIS, THE PROJECT WILL EXPAND THE FUNCTIONALITY OF THE RESTFUL API STANDARD AND IMPLEMENT ADDITIONAL API TECHNOLOGIES, WHILE MAINTAINING THE PROJECT INFRASTRUCTURE.
