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.
The Times They are a Changin’ International metadata standard ISO ANSI • transitional process • guidance documents and presentations • tools under development • stay the course (CSDGM) all shall be well…
The Times They are a Changin’ 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 • data discovery and clearinghouse operations • data exchange and use • data management • ESRI ArcCatalog • Intergraph SMMS 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 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 • 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…

ISO Topic Categories as Keywords • aids translation to ISO metadata • data can sort into geodata.gov ‘channels’
Document Planned Data Acquisitions • promotes data development partnering • required of federal agencies • $1 million current • $500,000 next fiscal year • geodata.gov • ‘Status’ provided as a data search element • calls for partnerships can be featured within Channels
Publish or Perish…geodata.gov 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 • 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 http://www.geodata.gov
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 see handout ‘Metadata Quick Guide’
