5. Purpose of the Standard Supports common uses of metadata Provides common set of terminology and definitions, and information about values to be provided Provides a common format for recording information about a data set

6. Structure of the Metadata Content Standard Sections Compound Elements Data Elements Nested Boxes Mandatory Mandatory if Applicable Optional

7. Visualizing the Metadata Content Standard Section

8. Compound Elements (2-dimensional boxes) Visualizing the Metadata Content Standard

9. Compound Element 1 Compound Element 1.1 Data Element 1.1.1 Data Element 1.1.2 Data Element 1.2 The Compound Element Compound elements are composed of other compound or data elements. The composition is represented by nested boxes. Compound Element 1 is composed of Compound Element 1.1 and Data Element 1.2 Compound Element 1.1 is composed of Data Element 1.1.1 and Data Element 1.1.2.

10. Visualizing the Metadata Content Standard Data Elements (3-dimensional boxes)

11. Compound Element 1 (can be repeated unlimited times) Compound Element 1.1 Data Element 1.1.1 Data Element 1.1.2 Data Element 1.2 If an element can be repeated independently from other elements, a label below the element name states how many times the element may be repeated. If there is no label, the element does not repeat independently from other elements. In the illustration, Compound Element 1 can be repeated an unlimited number of times. Thus, the following block of data is repeated: Compound Element 1 Compound Element 1.1 Data Element 1.1.1 Data Element 1.1.2 Data Element 1.2 Repeatable Elements
