GLAST Infrastructure Introduction
Goals of the Project
The primary goal of the project is to provide the software architecture and infrastructure for the GLAST Core Team to accomplish its mission. Specific goals include:
- Distributed SOA for GLAST data processing projects
- Lightweight, scaleable maintainable
- Team oriented approach (as opposed to individual contributors)
- Maximize talents of a small group
- Programmers
- Web Developers
- Occasionally-connected programmer/manager/astronomer
- Utilize talents of JAS group
