FORMAT/EXAMPLES	Although ice is generally thought of as rigid, glaciers are not stationary masses. In fact, in order to be considered a glacier, an ice mass must be of sufficient size and thickness to cause motion. Its sheer weight becomes so great that gravity forces a glacier to spread outward and downslope. A glacier moves according to its mass balance—the difference between how much snow and ice a glacier gains each year relative to how much it loses. When the amount of snow and ice accumulated on a glacier through precipitation or wind deposits exceeds the amount lost due to melting, wind erosion, or breaking off into the sea, it is said to have a positive mass balance year. During extended warm periods, when the snow and ice lost over a year exceeds what is gained, the mass balance is negative. While a series of positive mass balance years may prompt the glacier to advance downslope, a series of negative years may cause the glacier to recede. For most glaciers, advancing and receding are noticeable only over a long time. However, when glaciers recede rapidly, movement may be evident over just a few months or years. Glacial movement plays an important role in shaping landscapes. In mountainous regions, glacial erosion widens and deepens a V-shaped river valley that guides a glacier's flow. When the ice thaws, a U-shaped valley is revealed. Stray boulders that have been deposited far from their source, known as glacial erratics, often litter this transformed landscape. Deep grooves, or striations, in exposed bedrock are other telltale signs of glacial movement. In this collection of images, you can see evidence of what happens to the landscape, especially when valley glaciers recede. For example, in the Carroll Glacier pairing, the more recent image clearly depicts the U-shaped valley, the terminal moraine (debris pile) that marks the limit of the glacier's advance, and vegetation where previously only rocks were present. Also, much of the water seen covering the river valley has receded along with the glacier. Since 1900, most glaciers around the world have retreated. The retreat is probably linked to global warming, whose effect on ice could have potentially serious consequences for humans. Accelerated melting of valley glaciers could produce catastrophic flooding followed by long-term drought, which would affect hundreds of millions of people who rely on stable glaciers to provide water for agriculture and their drinking supply.

About the PBS Digital Learning Library Metadata ...

Current Version of PBS DLL Metadata is 1.2

Genesis of the PBS DLL Metadata

Preliminary drafts of proposed metadata elements for the Digital Learning Library were presented to PBS in February of 2008. Over the course of two years, with the release of version 1.2 of the PBS DLL Metadata in January 2010, the total number of elements was reduced from 109 individual descriptors to the current 69 metadata elements. See our timeline of version changes and the state of the elements on the web page entitled Metadata Schema Changes > Version Control & Change Orders.

This dictionary of metadata elements is considered to be an "Application Profile" because it draws its metadata elements from other established metadata dictionaries and schemas. An Application Profile is a...

...set of metadata elements, policies, and guidelines defined for a particular application or situation. The elements may be harvested from one or more element sets, thus allowing a given application or profile to use pre-established, well-formed, standardized metadata in addition to other metadata descriptors that are created and defined locally (custom metadata). For example, a given application might choose a subset of the Dublin Core that meets its needs, or may select elements from the Dublin Core, another element set, and several locally defined elements, all combined in a single schema. An Application Profile is not complete unless adequate documentation is provided in order to identify and specify definitions, policies and best practices associated with an application profile's use.

Must All of the Metadata Elements be Used?

Not all of the 69 element descriptions in Version 1.2 need to be supplied by content contributors. There are three types of metadata in the PBS DLL...

MANDATORY:
This small group of elements is required in order to provide basic descriptions about a media item and to facilitate searching.
OPTIONAL:
This set of metadata elements can be supplied by contributors if the descriptions exist and will enhance the findability of media items from the repository.
PROVIDED BY PBS:
This set of metadata is primarily supplied by PBS itself for each contributed media item and includes the correlations of media items to state and national core curriculum educational subject areas and learning objectives.
