There are multiple standards within the ISO Technical Committee 211 for geospatial standards. In many cases, multiple standards are required to adequately describe the unique characteristics of a dataset. In the case of ISO 19115 compliance, the most immediately relevant ISO standards are:
Additional standards focus on topics such as land cover, GML, geodesy, geppositioning.
It is important to note that, within one standard, multiple standards are often referenced (Figure 1).
A scenario for ISO conformance for a land cover product derived from radar data might follow the following steps:

In the end, the ISO family of standards is broad enough to allow for metadata on everything from high-level mission strategies to the details of provenance and instrument structure. The child pages contains links to normative references/standards pertinent to the generation and expansion of NASA ISO-19115 compliant metadata.

Thusfar, the NASA Best Practices for ISO 19115 have drawn upon conventions and extensions to ISO 19115:2003 and ISO 19115-2. They incorporate other forward-looking elements such as ISO 19115-1, lineage and have room for stakeholder outreach and feedback. Figure 2 illustrates the paradigm driving the Best Practices development process. (Figure 2).
