Construct a self-consistent data set to use within XSTAR Store atomic data with well-defined data types Build tools to intelligently combine the datasets into a master set Provide all these tools through the web Integrate to VAMDC
• How do we plan to do it?

Ever growing sets of data files Sequential modeling Time consuming consistency and integrity checks Manually modified files (error prone) Lack of standards, conventions and inconsistent data model Informal version control
• Narrow scope
No web tool available Advanced computer skills required System-dependent installation
XSTAR frontend
XSTAR backend

A solution approach: gXSTARA solution approach: gXSTAR
• GRID infrastructure
• General considerations
The web site will be based on Genius grid portal or VM Regular jobs will be used to run single XSTAR calculations Parametric JDL will be used to run XSTAR models

• General considerations
The db structure must be able to describe the data it contains Build a library of functions to act on the db Atomic data to be inserted will come in a variety of formats Being able to browse the database is essential (web and text based) Integrated within VAMDC frontend
