Abstract
Science projects are data publishers. The scale and complexity of current and future science data
changes the nature of the publication process. Publication is becoming a major project
component. At a minimum, a project must preserve the ephemeral data it gathers. Derived data
can be reconstructed from metadata, but metadata is ephemeral. Longer term, a project should
expect some archive to preserve the data. We observe that published scientific data needs to be
available forever – this gives rise to the data pyramid of versions and to data inflation where
the derived data volumes explode. As an example, this article describes the Sloan Digital Sky
Survey (SDSS) strategies for data publication, data access, curation, and preservation.
