Data Heterogeneity
Heterogeneity HighLow
•Tight coupling
•Simple subsetting
•Explicit semantics
•Loose coupling
•Hard subsetting
•Limited semantics
Data set size LowHigh

7.
Diverse Analysis and Modeling
• Wide variety of analyses used in ecology and
environmental sciences
– Statistical analyses and trends
– Rule-based models
– Dynamic models (e.g., continuous time)
– Individual-based models (agent-based)
– many others
• Implemented in many frameworks
– R, Matlab, SAS, SPSS, Jump, C, Python, Fortran

• Produce an open-source scientific workflow
system
• Design, share, and execute scientific workflows
• Support scientists in a variety of disciplines
• e.g., biology, ecology, oceanography, astronomy
• Features
• Data access
• Cross analytical packages
• Documentation
• Provenance tracking
• Model archiving and sharing

10.
Scientific workflows promote interoperability

11.
Why workflows?
• Executability
• Replicability
• Reproducibility
• Transparency
• Modularity
• Reusability
• Provenance

12.
How do we harness the long tail?
• Efficient data federation
• Interoperable software workflows
• Central search for discovery
• Just-in-time data integration
– Loose coupling
– Schema-less storage
