58 58 Open Source Initiative Action Plan Mission Statement Conduct a small Apache project that will enable us to learn to create tools for earth science data users that is developed and maintained primarily by the open source community. Stakeholders Key groups, organizations, individuals that will be impacted Earth science data users. EOS projects, Decadal Survey Missions, other NASA Earth Science data activities All HDF communities Who needs to be involved in developing deliverables. Developers and end users who work with NASA earth science data. Approach Achieve approval from NASA to make this project a part of the ESDIS project (EED Task 2 Rev 8). Identify a need that is likely to have community support. For example, a need for tools to convert HDF files to certain other formats. Learn to create and lead an Apache Incubator Project. Create an Apache Incubator project. Develop tools. Graduate the project from incubation. Outcomes, Deliverables, Milestones Specific outcome: the company learns to create an open source project in which HDF software is developed and used by the community Work products An Apache Incubator project An Apache project supporting the software Tools Recommendation report Milestones Periodic reports on steps in the approach. Incubator project established. Apache project achieved. Final report 10/16/2012HDF Briefing to NASA
