Earth Science Software Reuse

Welcome to the Earth Science Data Systems (ESDS) Software Reuse Working Group (WG) portal web site. Please visit the ESDS Working Group Page for some additional information about our group.

The WG is pleased to announce the recipients of the 2009 Peer-Recognition Award who received their awards at the 8th ESDS WG Meeting. Congratulations, and thank you for your reuse efforts.

We have updated our reuse definitions including what the Working Group does and does not consider reuse in our Resources, Library section, and posted a brochure about our group and its activities. A section on the Reuse Readiness Levels (RRLs) we have been developing has been added to provide easier access to all of the RRL material posted on the site. A number of bottom-up reuse guidelines, a technology transfer guideline, and a technology transfer FAQ to help explain NASA's technology transfer process are available in the Resources, Guideline Documents section. Some of our more recent publications added to the Resources, Library, Publications section include a book chapter in Aerospace Technologies Advancements (available through Sciyo.com or a link in our publications section), a DSADR paper discussing some of the WG's major activities, presented at a workshop during ICSR 10 (here are the DSADR slides used for the presentation), and our 2008 IGARSS paper about the current state of our Reuse Readiness Level work. Recent presentations added to the Resources, Library, Presentations section include two posters from the 2009 Fall AGU Meeting -- one is about measuring software reusability with RRLs and the other is about reuse tradeoffs in the NPP mission -- and our 2010 Winter ESIP Meeting poster on software reuse for environmental decision-making. Our full list of upcoming events is also in the Resources section, as is our list of some awards that are relevant to reuse projects, including the peer-recognition award developed by the WG (the nomination form is also available as a separate document). The reuse material used at our 2009 annual meeting is now available in the 8th ESDS WG Meeting folder under Resources, Library.

We have completed our survey to better understand the practice of software reuse within the Earth Science community. Preliminary survey findings are available on the web and have been published in a 2006 IGARSS paper. We have also posted some of our documents related to our proposed Reuse Enablement System (RES) in a new folder under the Resources section. Currently available documents include: a trade study of existing catalog and repository systems, use cases for the proposed RES, requirements for the proposed RES, an architecture study of existing software/system solutions that could be used to create the proposed RES, and a test plan to confirm the proposed RES will meet the identified requirements. Additional documentation as well as a roadmap and schedule for RES deployment are under development and will be added as they are completed.
