FDSN StationXML Schema
The purpose of the FDSN StationXML schema is to define an XML representation of the most important and commonly used structures of SEED 2.4 metadata.
The goal is to allow mapping between SEED 2.4 dataless SEED volumes and this schema with as little transformation or loss of information as possible while at the same time simplifying station metadata representation when possible. Also, content and clarification has been added where lacking in the SEED standard.
When definitions and usage are underdefined the SEED manual should be referred to for clarification. SEED specification: http://www.fdsn.org/publications.htm
Another goal is to create a base schema that can be extended to represent similar data types.
Examples will be provided in the future.
The targetNamespace of the document identifies the major version of the schema and document,
version 1.x of the schema uses a target namespace of
This combination of attributes and targetNamespaces allows the schema and documents to be versioned and allows the schema to be updated with backward compatible changes (e.g. 1.2) and still validate documents created for previous major versions of the schema (e.g. 1.0).
