OMS Briefing10 OMS Principles The Framework Is open source and platform independent Contains no commercial licensing API is non-invasive Leverages cloud computing capacity Promotes community modeling Emphasizes development in contemporary languages Models and Components Are open source Are annotated to facilitate linkage and re-use Are organized into model bases Are deployed as services and scaled to user load

OMS Briefing11 OMS Strategic Plan Goals Goal 1 – Through OMS the USDA modeling portfolio expands to meet priority agency and Department business needs. – Objective 1 – Develop four core agro-environmental model bases for: (1) management unit scale decision support, (2) management unit scale practice design, (3) ecosystem service and environmental credit determinations, and (4) USDA program analysis. – Objective 2 – Coordinate and build a comprehensive data provision services for OMS model bases. – Objective 3 – Create knowledge bases to (1) manage OMS model and component metadata, (2) define and manage core agro-environmental concepts and their relationships, and (3) transform scientific knowledge on static web pages to machine readable content. – Objective 4 – Expand, develop, and support the cadre of OMS modelers.

OMS Briefing12 OMS Strategic Plan Goals Goal 2 – USDA agro-environmental use increases to become ubiquitous at the field and watershed scales in the country. – Objective 1 – Deploy OMS models as registered, advertised services to run on an elastic computing cloud platform. – Objective 2 – Enable multi-threaded model runs to accommodate heavy user demand. – Objective 3 – Calibrate OMS models by physiographic region in a coordinated and consistent manner. – Objective 4 – Develop and deploy data access services for OMS models.

OMS Briefing13 OMS Strategic Plan Goals Goal 3 – OMS models are integrated with field research to extend and enhance results, and facilitate technology transfer. –Objective 1 – Evaluate agricultural systems in conserving non-renewable resources, improving environmental quality, and sustaining production for different soil and climate conditions. –Objective 2 – Explore management strategies that optimize the use of limited water and soil resources. –Objective 3 – Project effects of climate change on agriculture and the resource base and explore adaptive strategies; and project effects of agriculture on soil carbon and greenhouse gas emissions. –Objective 4 – Evaluate long-term potential and sustainability of bio- energy crops. –Objective 5 – PLACEHOLDER (describe role of ASRU here).

OMS Briefing14 OMS Strategic Plan Goals Goal 4 – Agro-environmental models are deployed and used across frameworks, facilitating collaborations involving USDA and external partners. –Objective 1 – Create and apply a non-invasive model development standard. –Objective 2 – Establish OMS as an open source community modeling system with appropriate governance. –Objective 3 – Develop collaborations to converge modeling framework principles and approaches.
