I need to provide identification information for the metadata resource.
A principle goal of metadata is to ensure that the data they describe can be independently understood and used effectively. The ISO Identification Information package provides fields for describing and unambiguously identifying objects associated with the resource.
The ISO 19115 Identification Information section includes fields for describing the resource, and for unambiguously identifying objects associated with the resource.
The Identification Information section of the metadata includes a citation to the resource being described. This citation should include a title, a unique identifier, and the version (edition) of the resource.
The MD_IdentificationInformation Object is an Abstract Object that holds general identification information for all kinds of objects. It is required and there can be any number of these objects in an MD_Metadata container. At present the MD_Identification Object can be instantiated either as a MD_DataIdentification Object, for datasets, or a MD_ServiceIdentification Object, for services.
The MD_Identification Object includes six simple elements shown inside the box in the Figure and eight associated complex objects shown as boxes outside of the MD_Identification Object. The simple elements are primarily textual descriptions that might be presented to users in a summary document or searched using full-text search mechanisms. The organizational/human contact is also included. The complex objects are described in more detail below.
This example shows the XML representation of the information required by ISO 19115 and NASA. As indicated in the conceptual model above, many important optional items also exist in the identification information.
