Metadata… again?
Metadata has long been promoted by the Federal Geographic Data Committee (FGDC), state GIS coordinators, and project managers as a means to: preserve organizational data investments instill data accountability and liability facilitate data sharing.

quality metadata is operational metadata…
GIS Internal Metadata
GIS tools enable data management via metadata: search for existing, in-house data products track updates, relates and other operations auto populate dataset properties preview data geography and dbase build templates for fixed descriptive info maintain multilevel metadata
metadata is the fuel for data management…
Go Beyond the Minimum
CSDGM mandatory elements are those common to all data types and organizations not most critical
value of metadata is to capture that which is unique
time spent early, saves time spent later
Create Templates
Boilerplate your metadata:identify all pertinent fieldsprovide content for fixed fields such as:
Use_ConstraintsContactsProcess MethodologiesDistribution Methods and Liability
create organization, theme, and project templates
Links to Services and Data
Online_Linkage is a repeatable field provide multiple links to:
data download data clearinghouse webmapping applications and services
enable users to locate data and related services…

Better Content = Better Performance
Robust and accurate metadata enables new functionality:
entity attribute descriptions yield feature-level metadata accurate dates facilitate data currency reviews detailed source tracking supports cost benefit analysis detailed process descriptions enable repeatable methodologies valid accuracy statements enable fitness for use assessments
metadata management is a GIS best practice
Quality Content
large data sets require a metadata strategy consider Originator as responsible party a Title is not a filename the Abstract summarizes the metadata USE Supplemental_Information make Use_Constraints meaningful consider Entity/Attribute Detailed_Description as an
opportunity to document your dbase
