First NASA mission to incorporate granule level ISO 19115-2
metadata attributes
HDF5 Metadata Groups
Produced via two methods
Level 2: XML serialization (XML bindings in software)
Level 3 and 4: XML style sheets conversions
Essential Metadata Attributes (Required and Recommended)
Both Series (Collection) and Dataset (Granule) level
Examples: Space/Time. Production and distribution attribution.
Processing lineage. Versioning history. Abstract.

3. 2016 ESIP Summer Meeting
HDF5 structure and metadata layout and the Essential Attributes in
the ISO Metadata Model
Plan
From the SWOT Information Archtecture (IA) and Use Cases, start
capturing the Essential Attributes in the ISO Metadata Model into a
knowledge representation framework.
Stage the Essential Attribute information in the framework for
design analysis, write specification documents for users, and write
metadata snippets for the HDF5 structure. This work will focus on
identifying the thin “top-level ontology” in the SWOT IA.
Extraction of the metadata to the framework.
Generate a specification document (e.g. Data Dictionary) for the
metadata.
Generate example metadata snippets appropriate for the HDF5 structure
