With IfcTester, you can author and read Information Delivery Specification - IDS - files and validate your IFC models against IDS to see if your model is compliant. After the audit, you can generate reports in console, as a web page, JSON or BCF file. It works from the command line, as a web app, or as a library.

from ifctester import ids, reporter
# create new IDS
my_ids = ids.Ids(title="My IDS")
# add specification to it
my_spec = ids.Specification(name="My first specification")
my_spec.applicability.append(ids.Entity(name="IFCWALL"))
property = ids.Property(
name="IsExternal",
value="TRUE",
propertySet="Pset_WallCommon",
datatype="IfcBoolean",
uri="https://identifier.buildingsmart.org/uri/.../prop/LoadBearing",
instructions="Walls need to be load bearing.",
minOccurs=1,
maxOccurs="unbounded")
my_spec.requirements.append(property)
my_ids.specifications.append(my_spec)
# Save such IDS to file
result = my_ids.to_xml("SampleIDS.xml")
# open IFC file:
my_ifc = ifcopenshell.open("MyIfcModel.ifc")
# validate IFC model against IDS requirements:
my_ids.validate(my_ifc)
# show results:
reporter.Console(my_ids).report()
