COMMON TERMS

Metadata - This is a formal definition of metadata. In data processing, metadata is definitional data that provides information about or documentation of other data managed within an application or environment.

FGDC – Federal Geographic Data Committee. A 19 member interagency committee with representatives from the Executive Office of the President, Cabinet-level and independent agencies. The FGDC is developing the National Spatial Data Infrastructure (NSDI) in cooperation with State, Local and tribal governments, academic community and the private sector. FGDC approved its metadata standard in June 1998.

CSDGM – The objectives of the Content Standard for Digital Geospatial Metadata is to provide a common set of terminology and definitions for the documentation of digital geospatial data.

ISO - (International Organization for Standardization) is the world’s largest developer of voluntary International Standards. Founded in 1947.ISO is a network of national standards bodies. These national standards bodies make up the ISO membership and they represent ISO in their country.

Clearinghouse – The Clearinghouse Activity sponsored by the FGDC, is a decentralized system of servers located on the Internet which contain field-level descriptions (or metadata) of available digital spatial data. The standard format facilitates queries and a consistent presentation.

Geospatial data – as defined by FGDC: information that identifies the geographic location and characteristics of natural or constructed features and boundaries on the earth. This information may be derived from, among other things, remote sensing, mapping, and surveying technologies

While the card-catalog entry is a form of metadata, it does not address topics such as

quality, accuracy, or scale. Well-written metadata describes these and

many more aspects of the data.

Page 10: Oy What is Metadata? j of Metadata. Metadata 101 joy of Metadata  Common terms  What is metadata?  Why metadata?

Metadata contains vital information

Without a label, how would you know which

one to open?

Dog Food?

Ravioli?

Imagine being given two identical cans.

Your task is to choose one to eat. But here’s the catch. Neither can has a label. Which would you choose?

Metadata is that component of data which describes it.

RARNUM - unique combination of species, concentration, and seasonality

CONC (concentration) = Density species is found at location

Season_ID = seasonality code like to the seasonal table

WHY DOES AN ORGANIZATION NEED TO BE ABLE TO TRACK ITS DATA OR WORK?

What about the employee who is ready to retire?

Do you know what he did or how he did it?

What were his processing steps?

What about the grad student who is leaving?

Do you even know where their data is?
