Archive Development Milestones

April 1998: The Gemini Science Committee (GSC) endorsed the following resolution concerning a Science Archive for Gemini:

"The GSC thinks a Gemini science archive is scientifically compelling. Such an archive would provide the scientific community with tools for effective online access to all Gemini science data and supporting information in order to promote further scientific exploitation of those data. The Gemini Science Archive should guarantee that the valuable datasets obtained with the Gemini Telescopes are usable by future generations for research and education. The Project should further study the implementation and the resources required for a Gemini science archive."

The Gemini Board has endorsed the GSC views on a Gemini Science Archive, and agreed that the Project should study the specifications and requirements for a science archive.

September 1998: In order to provide a basis for the science archive conceptual design activities, Gemini sponsored a workshop to asses the feasibility of a viable Gemini Science Archive and recommend prioritized specifications and requirements for the science archive. The Science Archive Workshop was held on Monday 14 September 1998, in the Gemini Hilo Base Facility, Hilo, Hawaii. The recommendations of the Workshop are given below as is a summary of the presentations and discussions.

Summary of workshop presentations and discussion

The Board also approved, for planning purposes, the use of a portion of Gemini operations funding for the development and continued support of a Gemini Science Archive. The Gemini Director has established a guideline of 5% of the Instrument and Facilities Development Fund (about $175K per year) for the continuing support of a possible Gemini Science Archive.
