Validating ISO Metadata Standards
Tools for Validation Schemas NameSpaces Schematrons
XML Schemas Defines the structure, content, and some semantics of XML documents Pattern that represents the data’s model and defines the objects, attributes, and relationships Defines the rules for the structure and content of an XML document
Which schema do I use? Use the schema reference at ished/xsd/schema.xsd – MD_Metadata root (19115) is found at gmd.xsd – MI_Metadata root ( ) is found at gmi.xsd – FC_FeatureCatalogue root (19110) is found at gfc.xsd Use biological schema set to document biological records (extends either MD or MI Metadata)
insert text insert text xmlns:gmi=“ xmlns:gmd=“ xmlns:gco=" Namespaces These codes are called namespaces. The namespace is a container providing context and rules for items. A definition of a term may change, depending on what namespace is applied.
Validation Tips <gmi:MI_Metadata xmlns:xsi=" xmlns:gmd=" xmlns:gco= “ xmlns:xlink=" xmlns:srv=" xmlns:gml=" xmlns:gsr=" xmlns:gss=" xmlns:gts=" xmlns:gmx=" xmlns:gmi=" xsi:schemaLocation="
Schematrons Used in conjunction with schemas Checks for additional validation that the schema cannot check – Content such as west bounding coordinate is west of the east bounding coordinate Delivers human-readable error messages
