@article {abbeloos_brapi_2019, title = {{BrAPI} - an Application Programming Interface for Plant Breeding Applications}, year = {Submitted}, abstract = {Modern genomic breeding methods rely heavily on very large amounts of phenotyping and genotyping data, presenting new challenges in effective data management and integration. Recently, the size and complexity of datasets have increased significantly, with the result that data is often stored on multiple systems. As analyses of interest increasingly require aggregation of datasets from diverse sources, data exchange between disparate systems becomes a challenge.To facilitate interoperability among breeding applications, we present the public plant Breeding Application Programming Interface ({BrAPI}). {BrAPI} is a standardized web service Application Programming Interface ({API}) specification. The development of {BrAPI} is a collaborative, community-based initiative involving a growing global community of over a hundred participants representing several dozen institutions and companies. Development of such a standard is recognized as critical to a number of important large breeding system initiatives as a foundational technology. {\^A}~The focus of the first version of the {API} is on providing services for connecting systems and retrieving basic breeding data including germplasm, study, observation, and marker data. A number of {BrAPI}-enabled applications, termed {BrAPPs}, have been written, that take advantage of the emerging support of {BrAPI} by many databases.More information on {BrAPI}, including links to the specification, test suites, {BrAPPs}, and sample implementations is available at https://brapi.org/. The {BrAPI} specification and the developer tools are provided as free and open source.}, doi = {10.1093/bioinformatics/btz190}, url = {https://doi.org/10.1093/bioinformatics/btz190}, author = {Abbeloos, Rafael and Vasques Costa, Bruno and Edwards, Jeremy D and Papoutsoglou, Evangelia and Finkers, Richard and Verouden, Maikel and Robbins, Kelly and Selby, Peter and Glaser, Philip and Sun, Qi and Gao, Star Yanxin and Laporte, Marie-Ang{\'e}lique and Rouard, Mathieu and Guignon, Valentin and Kilian, Andrzej and Pearce, Brian and Uszynski, Grzegorz and Hok, Puthick and Larmande, Pierre and {LeBauer}, David and Marshall, David and Stephen, Gordon and Milne, Iain and Shaw, Paul and Raubach, Sebastian and Mistry, Naymesh and Backlund, Jan Erik and Tovar, Clarysabel and Soldevilla, Nahuel and Neveu, Pascal and Ramirez-Gonzalez, Ricardo H and Rathore, Abhishek and Sarma, Chaitanya and Rife, Trevor and Simon, Reinhard and Basterrechea Salido, Martin and Lange, Matthias and Ghaffar, Mehmood and K{\"o}nig, Patrick and Scholz, Uwe and Lyon, David and Bauchet, Guillaume and Morales, Nicolas and Mueller, Lukas and Perez-Masias, Ivan and Benites-Alfaro, Omar and Birkett, Clay and Matthews, Dave and Raque, Angel M and Lagare, Jack Elendil B and Calaminos, Viana C and Semp{\'e}r{\'e}, Guilhem and Carceller, Pierre and Cyril Pommier and Cornut, Guillaume} }
