OPULS: NOAA S3 Data Access

Overview

With NOAA funding OPeNDAP collaborated with Deirdre Byrne, Jeff Ogata , and John Relph. This NOAA team had created a publicly accessible S3 bucket of data files, along with a directed graph catalog built of XML files. We wrote software for Hyrax that allowed Hyrax provide HTML and THREDDS catalog pages along with DAP data access. This was accomplished by writing a special version of the OLFS that could traverse the S3 held catalogs and could utilize the BES gateway function to retrieve (and cache) data files from S3 and provide DAP access to them.
