Feature MetadataMetadata is stored in the model in three related tables.

The Meta_DatasetDetail table holds information specific to the source of the data, i.e.; originator name, data accuracy

and currency, data source url, etc.

The Meta_ProcessDetail table holds fields specific to the processor (contact information) and the process used in

loading or updating the dataset features or objects.

The BPFeatureToMetadata table links the features and objects to one or more processes and their sources. This table gives the model the capability of lineage,

i.e.; tracking the history of changes for a given feature.

Each feature and object in the model is linked to the Meta_DatasetDetail table through the

Source_DatasetID field included in every feature class and object table. Certain metadata fields in the

Meta_DatasetDetail and Meta_ProcessDetail tables are included on the features and objects themselves to give the

user quick access to key metadata information.(See fields outlined in red).

For field definitions, please refer to the document Standard Content Standard for Digital Geospatial Metadata

(FGDC-STD-001-1998). http://www.fgdc.gov/metadata/contstan.html

This poster depicts the Best Practices model, version 1.1 and was created by the U. S. Geological Survey ,National Geospatial Technical Operations Center,

Denver, Colorado, 80225

The Best Practices Data model was developed as a collaborative effort between ESRI and the U.S. Geological Survey.

A “GIS for the Nation,” the Best Practices Data Model offers a data sharing informationtemplate to accommodate local, state, tribal, and national data needs.
