Welcome to ELSA

The Educational Labeling System @Atmospheres (ELSA) is a tool designed to help streamline the creation of PDS4 compliant labels. Data sets within the PDS4 archiving standard begin at the top with setting up the bundle file, which defines what collections you intend to include, and eventually includes products (your files + metadata labels). ELSA provides a consistent way to populate the XML labels with the unique identifiers that serve as the backbone of PDS4 in an easy and helpful way.
