Consequences of lack of standards
• It is difficult to compare models, even those constructed for the same pests, because the models have different inputs and outputs.
• The knowledge base for a model can easily be lost when the author retires or moves on
• Models are developed in many different computer languages, adding another obstacle to researchers who wish to compare, evaluate, validate or adapt existing models.
Challenges to developing standards
There is great variability in the design and construction of prediction models for plant pests, weeds, and diseases due to:•Biological diversity e.g., pests (weeds, fungi, arthropods, bacteria, etc.) and hosts •Diversity in modeling approaches, including the choice of algorithm and the associated biological and weather inputs and outputs.
Who would standards help?
• Researchers (modelers) wishing to share, build, or evaluate new models or adapt existing models to new pests/hosts
• Extension specialists wishing to build, evaluate or archive models
• Public and private service providers wishing to deploy new models
• Identify Agricultural Components Requiring Standards
• Compose a Glossary of Standard Agricultural Terms
• Develop a Standard API for Distribution to Industry
• Develop a XML Schema for Data/Information Sharing
• Address Security Issues of Information Ownership
• Create a Level Playing Field to Foster Innovation
• Fit Regulatory Concerns into Standards
• Identify Members to Lead Standards Movement
AgGateway Organization and Activities
• Database Structures
• Data Formats and Field Names
• Data Ownership, Privacy, and User Rights
• Variable Names, Definitions, and Units
• Model Structures and Configurations of Input and Output
• Application Programming Interface (API) Standard
• Web Services Description Language (WSDL ) Standard
• Security Levels for Information
• Equipment and Telematics Specification Guidelines and Standards
• Quality Control Procedures Including Objective Benchmarks
• Customer Service Center for Resolving Product Issues
Agricultural Components Requiring Standards
Our Job is to Identify Standards for Models
Potential areas for standards include•Model definitions•Model documentation•Model inputs, outputs and parameters•Model evaluation with observations•Model metadata•Model integration•Sharing of models and/or exchange of model outputs and executables through web services (i.e. XML)•Model applications especially for decision making in the field
Conclusion
The advent of webservices and the AgGateway initiative provides a unique opportunity to standardize and harmonize agricultural modeling, with plant pest models leading the way.
