Work Progress
Deliverables:
• Web-based Interface for Submitting Tcl File and Performing Analysis On-line
• Back-end (Relational) Database for OpenSees and Front-end Web Interface for Querying Analysis Results
Research / Prototyping:
• Web Applications Registration and Naming Service
• On-line Element Service: Distributed Element Service
• On-line Element Service: Dynamic Shared Libraries

Future Improvements
Data Access System: • Finalize the data access system design• Improve performance of data query• Provide user interface for data query
Distributed Model: • Standardize element interface• Further implement registration and naming service• Improve distributed element services
