Standard metadata section expands on the basics: full title, description, themes, keywords, category, creation date, last update date, and creator.
This is the information to reference when citing the dataset in a report or grant application.
Application and Case Studies section surfaces context that helps you understand how the data has been or could be used. It includes use cases, relevant case studies, and related reports.
If you're building a grant narrative or researching a topic, this section can save you significant time — the related reports are linked directly.
Contact and Support Information lists the agency website (memphistn.gov) and any available user support materials. For questions, use the key contact email in the sidebar.
Data Asset section contains the practical details for working with the data: years available, access type (whether the data lives directly on the DMS portal, not on an external site), and data export formats (for more guidance, see Downloads & formats).
Data Quality and Limitations is one of the most important sections to read before using any dataset. It includes the Geographic level, Data limitations, and Data collection and cleaning methods.
Always read the limitations note. It tells you exactly what the data can and can't be used to conclude.
