Introduction
GB/T 19710-2005 Geographic Information Metadata detailing the importance of describing metadata for geographic information.
GB/T 19710-2005 by defining a series of metadata elements and the establishment of a common set of terms, the definition and expansion of rules for a variety of geography
The description of the information provides a structural system. GB/T 19710-2005 is a basic standard for metadata related to geographic information
For a global view, but did not define the appropriate encoding rules.
GB/T 19710-2005 does not provide coding rules, so in the specific implementation of geographic information metadata, because of the various elements
Discrepancies arise from inconsistent understanding of the rules. In order to facilitate the realization of GB/T 19710-2005 standardization, the metadata to achieve the standard mention
A clear set of rule-based coding methods is provided for implementing GB/T 19710-2005. This guide is available in a set of technical documents
XML patterns to ensure interoperability, these patterns describe, test and exchange information about geographic data sets, data sets, geography
Metadata for elements, feature attributes, feature types, etc. provide a uniform specification.
GB/T 19710-2005 defines the common metadata in the field of geographic information. About Geographic Information Data Types and Geographic Information Services
More detailed metadata, as defined in the other Geographic Information National Standards and User Extensions (GB/T 19710-2005). This guideline technique
The purpose of the document is to provide rules for the implementation of common metadata, which are also considered where national standards for other geographic information need to be cited.
ISO 19118 "Geocoding" describes the need to generate coding rules based on UML patterns and the coding rules based on XML
Then, and introduced the XML. This instructional document utilizes the coding rules defined in ISO 19118 to define how to get from
The UML model in GB/T 19710-2005 derives the technical details of the XML Schema.
Implementation of Geographic Information Metadata XML Schema
1 Scope
This Guidance Document dictates the coding method of Geographic Information Metadata XML (gmd) and the coding method of GB/T 19710-2005
XML mode to achieve.
This guidance document is applicable to the sharing and exchange of geographic information metadata over the Internet or offline.
