*** SCHEMA EXPLANATION **** This is the MAIN schema for the News and Opportunities metadata framework. This MAIN schema calls other VOCABULARY schemas to create the metadata framework structure. *** NAMESPACES ******** The chameleon approach to namespace conventions is used in the VOCABULARY schemas. Only this MAIN schema has a target namespace. The VOCABULARY schemas do not have target namespaces (allows for plug-n-play components and vocabularies). *** ROOT ELEMENT ***** The root element of this schema is news-oppsRecord. *** SCHEMA DEVELOPMENT ***** The Venetian Blind approach is used for this MAIN schema and all VOCABULARY schemas. Elements within all schemas are used for fields (quantities) of the metadata framework. When elements have controlled vocabularies that are hierarchal, the vocabularies appear in the element as a colon separated text string. Attributes are used when additional information is required for the content of an element or if two pieces of information are required. *** DEFINING COMPLEX and SIMPLE TYPES ******* Since the metadata framework uses Venetian Blind schema development, most metadata fields are defined as complex or simple types. This improves re-use for other frameworks developed at the DLESE Program Center (DPC) or within the DLESE community. As such, each schema has a complex and simple type section. Built-in simple types are defined when an elment is defined. Derived simple types are used when a metadata field appears more than once or if restrictions are needed on element content. *** LICENSE INFORMATION ***** Copyright 2002, 2003 2004 2005 DLESE Program Center University Corporation for Atmospheric Research (UCAR) P.O.
