Incorporating ISO Metadata Using HDF Product Designer
Download as PPTX, PDF0 likes592 views
This document discusses incorporating ISO metadata standards into HDF files using the HDF Product Designer tool. It describes how the HDF Product Designer allows users to import pre-built ISO metadata components from a separate project into their HDF file designs. This allows essential contextual data or metadata to be stored in HDF5 files according to ISO 19115 standards.

Sample of Python Code
# Group: /gmi:acquisitionInformation
grp_1 = f.create_group('gmi:acquisitionInformation')

- 2. SESIP_0716_AJ 2 The Problem The need for more contextual data (metadata) in HDF5 files is growing.
- 3. SESIP_0716_AJ 3 The Solution Use the current conventions to the their fullest extent. Store the rest of metadata using the ISO 19115 standards.
- 4. SESIP_0716_AJ 4 HDF Product Designer Can Help • Support for the most widely used Earth science metadata conventions. • The latest release (v1.4) allows import of ISO metadata objects into user designs.

- 9. SESIP_0716_AJ 9 Importing ISO Objects All groups in the ISO design have default role and type attributes. Do not change these! Repeating roles have "_<uniqueID>" added to their names
