public class ModelAndSyntaxTests
extends SchemaModelFixture

Includes tests for adherence to mandatory GML model and syntax constraints. A GML object is an element assigned to the gml:AbstractGML substitution group (and thus is derived from gml:AbstractGMLType). Note that the so-called "object-property model" is very similar to the "striped" encoding syntax convention used in RDF/XML representations, where elements alternately represent nodes (resources) and edges (properties).

verifyGMLObjectPropertyPattern

public void verifyGMLObjectPropertyPattern()

[Test] A GML property is a child element of a GML object; such a property cannot itself be a GML object (i.e. derived from gml:AbstractGMLType). Furthermore, it must not declare any attributes of type xsd:ID.

• ISO 19136:2007, A.1.1.7: Property elements are not object elements

isGMLObject

boolean isGMLObject(org.apache.xerces.xs.XSElementDeclaration elemDecl)

Determines if an element is a GML object. A GML object is an XML element of a type derived from gml:AbstractGMLType.

Parameters:

elemDecl - An XSElementDeclaration object.

Returns:

true if the element corresponds to a GML object; false otherwise.

• "ISO 19136:2007, 7.1.3: XML schema definition of GML language"
• "ISO 19136:2007, 7.2.4.1: Derivation from AbstractGMLType"

hasIDTypeAttribute

boolean hasIDTypeAttribute(org.apache.xerces.xs.XSElementDeclaration elemDecl)

Determines if the type definition for the given element declaration includes an attribute of type xsd:ID. Only GML objects should have one (gml:id).

Parameters:

elemDecl - An XSElementDeclaration object.

Returns:

true if the element content model contains an ID type attribute; false otherwise.
