Re: [Bimserver-devel] Use of IfcXmlWriter

[Nicholas N. <nn...@ae...>]

Would it be timely to mention that the XML produced is not compliant with the XSD issued by buildingSMART ?
There are three issues:

(a) header

The <ifc:uos> ... </ifc:uos> should be < uos> ... </ uos>

(b) set and list

ex:cType="list" and ex:cType="set" are used incorrectly (perhaps even always the wrong one). I removed them all.

(c) IFC defined types.

Many, many fields that are simple types are reported as complex types. An example is:

		<IfcShapeRepresentation id="i56441">
			<ContextOfItems>
				<IfcGeometricRepresentationContext xsi:nil="true" ref="i54795"/>
			</ContextOfItems>
			<RepresentationIdentifier>
				<IfcLabel>Axis</IfcLabel>
			</RepresentationIdentifier>
			<RepresentationType>
				<IfcLabel>Curve2D</IfcLabel>
			</RepresentationType>
			<Items >
				<IfcPolyline pos="0" xsi:nil="true" ref="i56442"/>
			</Items>
		</IfcShapeRepresentation>

Which should be 

		<IfcShapeRepresentation id="i56441">
			<ContextOfItems>
				<IfcGeometricRepresentationContext xsi:nil="true" ref="i54795"/>
			</ContextOfItems>
			<RepresentationIdentifier>Axis</RepresentationIdentifier>
			<RepresentationType>Curve2D</RepresentationType>
			<Items >
				<IfcPolyline pos="0" xsi:nil="true" ref="i56442"/>
			</Items>
		</IfcShapeRepresentation>


The IFC defined types should only appear on lists and where select types are used.

Whilst I probably dont have the expertise to fix these, I am happy to validate any new samples.

Regards,
Nick.

Hello Anders,

The "No source code is available for type java.io.File" is strange because it's a standard java class.
Are you able to run a simple hello world program in your project?
Could you check if you have a JRE/JDK library referenced in your dependencies as well, and also what Java Compiler is used for the project (see Project properties)?

Kind regards,
Ruben de Laat
