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.

  • transitional process
  • guidance documents and presentations
  • tools under development
  • stay the course (CSDGM)

Geospatial One-Stop

one of 19 federal e-gov initiatives

Portal to:

  • NSDI Clearinghouse
  • other metadata servers
  • web map applications
  • geospatial research and related information
metadata official language for the geospatial community
Metadata: official language for the geospatial community
  • data discovery and clearinghouse operations
  • data exchange and use
  • data management
    • ESRI ArcCatalog
    • Intergraph SMMS

quality metadata is operational metadata…

arccatalog and metadata
ArcCatalog and Metadata

ArcCatalog provides data management:

  • 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
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
Create Templates

Boilerplate your metadata:

  • identify all pertinent fields
  • provide content for fixed fields such as:
    • Use_Constraints
    • Contacts
    • Process Methodologies
    • Distribution Methods and Liability

create organization, theme, and project templates

links to services and data
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…

Metadata Harvest

  • Register node/service at geodata.gov
  • metadata will be regularly harvested & updated
  • harvest counselor program

Metadata Upload

  • register and upload at geodata.gov

Metadata Online Creation

  • online tool at geodata.gov for bare metadata creation
visit geodata gov
Visit geodata.gov
  • search for geospatial data and applications
  • access, compile & download data from different sources
  • seek out data development partnerships
  • create and upload metadata
  • join a thematic Channel Community

better content better performance
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
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

see handout ‘Metadata Quick Guide’
