Metadata again

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

The Times They are a Changin’

International metadata standard

ISOANSI

  • transitional process

  • guidance documents and presentations

  • tools under development

  • stay the course (CSDGM)

    all shall be well…


The times they are a changin1

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

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…


Iso topic categories as keywords

ISO Topic Categories as Keywords

  • select one or more categories to aid in data search and discovery (see handout)

Iso topic categories as keywords1

ISO Topic Categories as Keywords

  • aids translation to ISO metadata

  • data can sort into geodata.gov ‘channels’


Document planned data acquisitions

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

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

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

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’
