What IS Metadata?
Data ‘reporting’ WHO created the data?
WHAT is the content of the data?
WHEN was it created?
WHERE is it geographically?
HOW was the data developed?
WHY was the data developed?

Project Management:Contract Deliverables
Metadata is a data component therefore part of any data deliverable
Clearly specify your metadata requirement via a metadata:
classification/validation schema, e.g. ‘level’ of metadata
template
specification manual
Provide a sample record if possible

Conclusions
If created with utility in mind, metadata can serve multiple roles:
and this is only human utility of metadata…
archivist preserve lineage
accountant preserve investment
developer document process
manager track progress
contributors communicate
consumer locate, assess, access data

Data Management:Reality Check
Discussion Questions:
Which of these data and project management metadata applications are you most likely to use and why?
Are there additional metadata applications that would serve your organization?

How Do I Create Metadata?
Steps to Success:
1. Understand the organization and content of the CSDGM
2. Learn to use the CSDGM Workbook (aka The Greenbook)
3. Select a metadata editor tool
4. Apply the CSDGM to your data
![Page 47: Making Metadata Work For Your National Climate Data Center Asheville NC February 2006 Lynda Wayne US Federal Geographic Data Committee / GeoMaxim Mike](https://reader030.vdocument.in/reader030/viewer/2022033101/56649e555503460f94b4d0e5/html5/thumbnails/47.jpg)

CSDGM Overview
The CSDGM documents:
digital geospatial datadigital geospatial data
imagery digital land surveysGIS files geographic databases

CSDGM Overview
Standard is organized into seven primary sections
There are three ‘supporting’ sections that repeat within the primary sections:
citation• a standardized way to cite the data and source data
time period information• a standardized way to record dates
contacts• a standardized way to document contacts

Metadata Tools
How do I determine the best metadata tool?Does your organization provide a tool that meets specific data management objectives?Does your GIS software provide an internal metadata editor?Do you need a tool that supports one or more CSDGM Profiles or Extensions? Do you need to document data resource beyond those managed within your GIS? Do you need a tool that is easily distributed to partners? What features are most important to you?

the good news….
XML supports consistent and robust implementation via software tools
• Format and exchange- current implementation - txt, doc, db file, etc.
- exchange format is txt
• Internal metadata harvesting and other automated features

the not-so-great news….
Standard can no longer be ‘read’ by most geospatial data developers
greater dependency on tools
lack of direct contact difficult for some metadata creators - analogous to moving from command line to GUI

Crosswalks drafted for:CSDGM Vers. 2.0
Dublin Core, others
Conversion software in development:FGDC sponsored effort with Intergraph /SMMS for standalone
ESRI has drafted for ArcCatalog
What about legacy metadata?

Now….1. Continue creation using CSDGM vers.2 !!!
2. Use ISO-poised softwareESRI ArcCatalog
Intergraph / SMMS
MetaD, FGDC/Polytechnic University Catalunya
3. Add Topic Categories as theme keywords with ‘ISO 19115 Category’ as keyword thesaurus
4. Monitor FGDC website for news, materials, and training opportunities
How do I prepare?

Soon…1. Educate and inform your organization that a
migration, and assistance, is in the future
2. Develop a metadata conversion plan using crosswalks and conversion software
3. Adopt ‘CSDGM vers. 3.0’ when finalized
How do I prepare?

Why Metadata?
Utilizing External Data….

Why metadata?
Be a part of the BIG picture
Federal Geographic Data Committee (FGDC)- coordinates national geospatial data development
National Spatial Data Infrastructure (NSDI)- creation and distribution of seamless national geospatial data
Global Spatial Data Infrastructure (GSDI)- creation and distribution of seamless global geospatial data

Who creates metadata?
OfficiallyFederal organizations producing digital geospatial data
Federally funded projects that produce digital geospatial data
Morally and practicallyAnybody that creates digital data
It’s the right thing to do!
