XML: ADN version 0.6.50

This page provides links to the XML files (main schema, controlled vocabulary schemas and instance documents) for a specific framework and version number. DLESE metadata uses XML schema and therefore the DLESE metadata frameworks are strongly data typed and are often maintained across several XML schema documents. The schemas for a particular framework are organized via an overarching or main schema (see below). This main schema may call different category and vocabulary schemas to create the framework.

To obtain all the XML schema files as a bundle for a particular framework and version, please contact support@dlese.org and request either a unix tar file or a windows zip file. Be sure to include the name of the framework and the desired version number (e.g. ADN version 0.6.50).

Main schema

  • record.xsd (Include this schema in instance documents (metadata records) for validation)
  • news-oppsRecord is the root element
  • No category schemas exist, just vocabulary schemas

Category schemas

The category schemas define distinct sections of the adn item-level metadata framework. The schemas are:

  • Commonfields - common fields across the different categories of the framework
  • Educational - educational or pedagogic features like audience, learning goals, grade range, standards
  • General - describes the overall characteristics of a resource collection (e.g. subjects, keywords, audience, title, description)
  • Geospatial Coverages - describes the area of the surface of the Earth (or other planetary body) that a resource is about, includes bounding boxes and detailed geometries using latitude and longitude coordinates
  • Lifecyle - describes resource creator and publication information
  • MetaMetaData - resource cataloger information and conditions of use of the metadata
  • Relations - relationships to other resources
  • Rights - describes rights, copyright information and conditions of use of the resource
  • Objects in Space - objects not of our solar system but that can be located by right ascension, declination and epoch
  • Technical - describes computer requirement for online resources or access information for offline resources
  • Temporal Coverages - describes temporal characteristics like time in the past, present, future and relative, that is, time (AD, BC or billion or millions of years ago)

Vocabulary schemas

Fixed schema values

  • metaMetadata.scheme: ADN (ADEPT/DLESE/NASA Alexandria Digital Earth Prototype/Digital Library for Earth System Education/National Aeronautics and Space Administration)

Sample records

  • record.xml (catalogs an online resource; shows example entries for almost every metadata field; evolves as the framework evolves)
  • required.xml (shows only required metadata for an online resource)
  • physical-object.xml (catalogs an offline resource like a rock; only the technical tag set changes
