Next Step - Metadata Components
Decide on important content – is it the same for all roles? Create consistent content for people and organizations and connect to CMR. Components - Reusable consistent descriptions of people and organizations xLinks

Additional Attributes
ECHO additional attributes (Product-Specific Attributes (PSAs)), are parameters that are not included in the ECHO metadata standard which further describe the data in each granule within a collection. These additional attributes are not part of the standard, so the only chance for users to understand them is using the information in the metadata record.
13
Properties Additional Attributes Properties:
ECHO includes a comprehensive model of information related to additional attributes (see list below). As these data are shared across disciplines and users, it is critical that the additional attributes are completely described. Additional Attributes Properties: Name – Unique name of the additional attribute. DataType – Data type of the additional attribute, chosen from the supported list of types. Description – A textual description of the attribute to help end users understand the purpose and data represented by the attribute. MeasurementResolution – Identifies the smallest unit increment to which the parameter value is measured. ParameterRangeBegin – Minimum value of all attribute values that will be provided by the collection or granules. ParameterRangeEnd – Maximum value of all attribute values that will be provided by the collection or granules. ParameterUnitsOfMeasure – Unit of measure for parameter (e.g. AVHRR: unit of geophysical parameter-units of geophysical parameter.) ParameterValueAccuracy – Estimate of the accuracy of the assignment of attribute value. This can be specified in percent or the unit with which the parameter is measured. ValueAccuracyExplanation – Defines the method used for determining the parameter value accuracy.

Quick Evaluation: Additional Attributes
The ECHO AdditionalAttribute model is very complete, but it is not consistently implemented.
