Writing Metadata
Working Towards Best Practices for SEFSC
Metadata Publication
Metadata Validation. Ensure that the metadata is standards compliant (follows the standard in use).
Metadata Approval. The metadata should be reviewed and approved by a Subject Matter Expert or other Program Manager, in accordance with existing policies.
Metadata Publication. Publish the metadata to a clearinghouse, WAF, or other repository so that the metadata content is publicly available.
Metadata is WAF can be harvested to data.gov, noaa.data.gov as needed.Discovery Portal
Data Inventory
Metadata Creation. Who will write the metadata? It is easier for someone more familiar with the data to write the metadata. Who will be responsible for metadata updates? Which tools will be used to create the metadata?
Updates
Metadata Assessment. First, a data inventory of the data that needs to be documented should be performed. What kind of data is it? How is the data going to be made available? Where will the data reside? Where will the data be archived?

Writing Metadata
• Before you begin writing, get organized
• Document your data as you go• Write so others can
understand• Always review your document
Keep Your Reader In Mind• Write simply but completely• Document for a general
audience• Be consistent in style and
terminology• Define acronyms• Avoid using jargon• Clearly state data limitations
Writing Metadata• Write a complete “Title”
• What • Where • When• Who
Which is better?
Greater Yellowstone Rivers from 1:126,700 Forest Visitor Maps (1961-1983)
The title is critical in helping others find your data.
Vague: We checked our work and it looks complete.
Specific: We checked our work using 3 separate sets of check plots reviewed by 2 different people. We determined our work to be 95% complete based on these visual inspections.
Be specific. Quantify when you can.
Select your keywords wisely
• Use unambiguous words
• Use descriptive words
• Fully quality geographic locations– Don’t rely on extent– Use place keywords as well
VARIOUS STANDARDSTools and Techniques
Creation Methods – ISO • Several ways to create ISO Metadata
• Transform from existing metadata• Use templates• Create from “scratch”

Creating ISO Metadata From “Scratch”
General Steps for XML Editors• Open Editor• Create New XML Document• Associate Schema with XML Document
– Use Offline Schema OR– Online Schema
• Select Root Element – MI_Metadata
• Edit File in Editing Window– Use Entry Helper Features– Use Auto-population Features
Your input here is an
xml version of a CSDGM
record.
XSLT Transformationcsdgm2iso19115.xslt
Your result is an xml instance of an ISO 19115
record.
Transforming Metadata
Existing standard metadata
Target metadata standard format
Transforming Metadata
This is a part of the mapping for FGDC CSDGM to ISO 19115.
Comments are Best Practices or Questions
Other Transformations• ISO to FGDC• DIF to ISO• FGDC THREDDS• netCDF to ISO• Various ISO and FGDC views• Custom transforms – from databases to metadata standards
