  * Ecological Metadata Language (EML) - Access control descriptors

  *

  *      Authors: Matt Jones, Zheng Wang, and Noah Goldstein

  * Organization: National Center for Ecological Analysis and Synthesis

  *  For Details: http://www.nceas.ucsb.edu/

  *      Created: 1997 August 19

  *     Modified: 1999 June 23

  *      Version: 1.4

  *    File Info: '$Id$'

  *

  * Ecological Metadata Language is a general purpose metadata content

  * specification for documenting ecological data.  The specification

  * consists of a series of modular document type definitions (DTD) that

  * provide metadata content descriptors. It describes the owner and

  * contents of the dataset  (eml-dataset.dtd), the research context in

  * which it was created (eml-context.dtd), the structural

  * characteristics of data files (eml-file.dtd), the

  * characteristics of variables in a file (eml-variable.dtd), current

  * status of data and metadata files (eml-status.dtd), access control

  * rules regarding the data  and metadata (eml-access.dtd), software

  * information (eml-software) and a variety of miscellaneous

  * supplemental descriptors (eml-supplement.dtd).

  *

  * Files generated under the structural constraints of eml are

  * plain-text files and therefore are editable in ordinary

  * text-processors.  However, these DTDs are intended for use within

  * general purpose metadata editors, and within a more specific

  * metadata editor being developed at NCEAS for the ecological

  * community.  This metadata editor will provide facilities for

  * version control and efficient metadata entry.

  * The purpose of this specification was to formalize the

  * Michener et al. work in a structured language to examine its

  * application to ecological data in a controlled manner.

  *

  * This specification was based on the work of the Ecological Society

  * of America's Committee on the Future of Long Term Data, and more

  * specifically on a related paper, Michener et al., 1997. See:

  * Michener, William K., et al., 1997. Ecological Appications,

  * "Nongeospatial metadata for the ecological sciences"

  * Vol 7(1). pp. 330-342.

  *

  * Where appropriate, we have used elements of the ISO/TC 211 draft

  * standard - the ISO Geographic information/Geomatics standard,

  * which includes xml code, as well as ISO 8601 schema. Some elements

  * in the ISO/TC 211 were expanded to allow for greater

  * resolution.

  *

  * For an explanation of the classes of metadata and elements defined

  * below, see Michener et al. 1997. In particular, the numbered comment

  * labels found below refer to Table 1 (pp. 336-337) of Michener

  * et al. 1997. In addition, each of the principal elements in the

  * specification is accompanied by a FIXED attribute called "description"

  * that provides a brief description of the content of the element. These

  * descriptions are derived from Michener et al. 1997.
