I need attributes in my metadata that are specific to my product |
The ECHO and ISO metadata models both include the ability to add non-standard elements required by specific communities:
ECHO Additional Attributes have the following properties:
Section | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
The ECHO Collection Level Metadata includes 149 structured elements and 327 Additional Attributes, so they are an important part of the existing metadata. The additional attributes need to be classified in order to attach them to the correct object in the ISO metadata. Preliminary categories and examples are shown here. These will almost certainly change as the categories are reviewed.

Some existing AdditionalAttributes include information that fits in an existing ISO 19115 element without the NASA extensions. In this case, custom translations are required. The details of these translations are described here.
