Metadata

metadata answers questions about data One way to discover data or learn about the data on the Maine Tracking Network is to explore its metadata.

What is metadata?

Metadata is often called "data about data." Metadata is a text document that describes the data, so that a potential data user can decide whether or not the data are appropriate to use. Metadata may include information about the context, quality and condition, or characteristics of the data.

What can I learn from metadata?

Metadata answers these questions:

Who collects and distributes the data?
What is the subject, processing, projection of the data?
When, where, why, and how were the data collected?
How should the data be used?

Where can I find metadata for the topics in the data portal?

Birth Outcome Metadata: Preterm Births and Very Preterm Births	The Maine EPHT program receives birth certificate data annually from ODRVS.
Birth Outcome Metadata: Sex Ratio	The Maine EPHT program receives birth certificate data annually from ODRVS. The ratio of male to female births (sex ratio) among Maine residents is analyzed, stratified by birth year, and geographic resolution.
Birth Outcome Metadata: Total Fertility	The Maine EPHT program receives birth certificate data annually from ODRVS. The total fertility rate among Maine residents is analyzed, stratified by year and geographic resolution.
Cancer Metadata: All Measures	The Maine EPHT program receives cancer data annually from the Maine Cancer Registry. Adult and childhood cancer rates among Maine residents are analyzed, stratified by year, geographic resolution, gender and sex, when appropriate.
Carbon Monoxide Metadata: Detectors	This data set contains information on the percent of homes in Maine with one or more CO detectors. Data are stratified by geographic location and housing type (i.e. rent, own). Detector prevalence data are derived from the BRFSS survey of Maine residents.
Carbon Monoxide Metadata: Mortality	The Maine EPHT program receives mortality data from Maine’s ODRVS. Unintentional and non-fire related carbon monoxide (CO) deaths among Maine residents are analyzed in order to assess trends over time.
Carbon Monoxide Metadata: Near Real-time Emergency Department (ED) Visits	Near real-time emergency department visit data for potential carbon monoxide exposures are from the Maine CDC Infectious Disease Program’s syndromic surveillance system.
Childhood Lead Poisoning Metadata	In collaboration with the Maine CDC’s Maine Childhood Lead Poisoning Prevention Program (CLPPP), the Maine EPHT Program receives blood lead test data for all Maine children < 6 years of age from the Health and Environmental Testing Laboratory (HETL) and directly from healthcare providers.
