LCC XML Document Metadata Element - USEPA/ATtILA2 GitHub Wiki

Metadata Element

Basic structure of ATtILA's Land Cover Classification schema XML document: Metadata element.

<metadata>
	<name></name>
	<description></description>
</metadata>

The Metadata element contains the name of the coding schema along with a brief description. ATtILA requires the Metadata element to be present when it parses the the XML document, and it cannot be empty. The Metadata element must contain the following two elements:

  • name - text, land cover coding schema name
  • description - text, description of land cover coding schema

Example Metadata element:

<metadata>
	<name>NLCD</name>
	<description>National Land Cover Database</description>
</metadata>

The information contained in the Metadata element is for informational purposes only. It is displayed in the Land Cover Classification Editor's Metadata window, and only there. The entries for the name and description attributes can be as long or as short as the user desires.

XML Note

  • XML is case-sensitive and care should be used when editing the LCC XML documents using a text editor. Wherever possible, element and attribute names for the document have been defined using lowercase characters. The only current exceptions are the attributes "Id" and "Name" in the Coefficients, Values, and Classes elements. If editing an LCC XML document outside of the Land Cover Classification Editor, these attributes should be capitalized wherever they appear.

  • You may notice that in the Metadata element, the <name> element is lowercase. The distinction here is that "name" in the Metadata element pertains to an element, and that the capitalization rule only applies to an element's attributes.
