Metadata 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 metadatafields 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).

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.
