DEVELOPMENT OF GCP ONTOLOGY FOR SHARING CROP INFORMATION Develop a validation process for ontology terms involving a community of crop experts and botanists.Apply the GCP ontology in the GCP phenotyping templates for annotation of representative data sets by researchers and integrate it into crop databases, e.g. the International Crop Information System (ICIS).To provide a browser interface for searching ontology terms or specific ontology hierarchy and an annotation page for annotating GCP datasets with GCP ontology.To integrate ontology management into the GCP platform for distributed integration of data across the Internet.Integration with plant ontology (PO) and gramene trait ontology (GTO), to develop a common, internationally-shared crop trait and anatomy ontology. FUTURE STRATEGYWithin the Consultative Group on International Agricultural Research (CGIAR), there is an enormous volume of agriculture-related information that is generated. In the past six or seven decades the CGIAR has accumulated historic crop datasets that are related to phenotype, breeding, germplasm, pedigree, traits, etc. However, available data is not systematically formatted and annotated which complicates data management, retrieval, and accessibility. Therefore, the Generation Challenge Programme (GCP) is deploying crop ontology to semantically characterize these datasets. The GCP crop ontology and associated open source software framework is described on the GCP “ Pantheon" project web site (http://www.pantheon.generationcp.org).INTRODUCTION 1Crop Research Informatics Laboratory - Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT), Mexico; 2Crop Research Informatics Laboratory - International Rice Research Institute (IRRI), Philippines; 3Centro Internacional de la Papa (CIP), Peru; 4International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), India; 5Bioversity International, Montpellier, France; 6Generation Challenge Programme (GCP), Mexico. *Principal InvestigatorI. GCP crop ontologyThe GCP ontology consolidates and adds to existing public ontology by indexing each ontology within the model in a consistent fashion.The GCP ontology focuses on crop-specific anatomy, development, and trait ontology for the GCP mandate crops (Figure 2) and provides the exact meaning of terms related to phenotypes described by crop physiologists, plant breeders, and other crop scientists.Figure 5. Overview of the GCP semantics. Part I indicates submenus under the main menu GCP semantics (http://pantheon.generationcp.org/index.php). Part II indicates an overview of the application part of crop ontology which is ongoing at present. The light rectangular box represents the major GCP target ontology domains.

Importance of deploying the GCP crop ontologyData related to phenotype and genotype available in CGIAR databases cannot be annotated by current ontologies because necessary terms are missing.Free text is used for complex descriptions of phenotypes and trait names which is almost impossible to index and search in a meaningful way (Figure 3).AVAILABILITYThe GCP ontology and platform are described on the pantheon website (http://pantheon.generationcp.org) (Figure 5).The CropForge software project management site (http://cropforge.org/projects/gcpontology) provides both the latest releases and previous versions of ontology flat files, which describe the terms, relationships, definitions, software tools, forums, and mailing lists for communication among collaborators. Additional documentation for scientific end users of the GCP ontology is being established (http://mcclintock.generationcp.org/). Decomposing complex trait names into several simple terms and allocating these terms into various ontology domains (Figure 4) is necessary to properly annotate available data related to crop phenotypes.Figure 2.
