[IDS] Creating an IDS file with a python script

Martin156131

Here is the sample ids file from bSI: https://github.com/buildingSMART/IDS/blob/master/Documentation/library/sample.ids

I did create a script as a challenge to recreate that sample ids file, see below:

from ifctester import ids, reporter

my_ids_path = r"C:\pathtoidsfile\sample.ids"

# create new IDS
my_ids = ids.Ids(
    title="buildingSMART Sample IDS",
    copyright="buildingSMART",
    version="1.0.0",
    description="These are example specifications for those learning how to use IDS",
    author="[email protected]",
    date="2022-01-01",
    purpose="Contractual requirements",
    )

# add specification to it
my_spec = ids.Specification(
    name="Project naming",
    minOccurs=0,
    maxOccurs="unbounded",
    ifcVersion="IFC4",
    description="Projects shall be named correctly for the purposes of identification, project archival, and model federation.",
    instructions="Each discipline is responsible for naming their own project.",
    )

my_spec.applicability.append(ids.Entity(name="IFCPROJECT"))

attribute = ids.Attribute(
    name="Name",
    value="TEST",
    instructions="The project manager shall confirm the short project code with the client based on their real estate portfolio naming scheme.",
    )

my_spec.requirements.append(attribute)

my_ids.specifications.append(my_spec)

# add an second specification to it
my_second_spec = ids.Specification(
    name="Fire rating",
    minOccurs=0,
    maxOccurs="unbounded",
    ifcVersion="IFC4",
    description="All objects must have a fire rating for building compliance checks and to know the protection strategies needed for any penetrations.",
    instructions="The architect is responsible for including this data.",
    )

my_second_spec.applicability.append(ids.Entity(name="IFCWALLTYPE"))

restriction = ids.Restriction(
    base="string",
    options={"pattern": "(-|[0-9]{2,3})\/(-|[0-9]{2,3})\/(-|[0-9]{2,3})"},
    )

property = ids.Property(
    name="FireRating", 
    value=restriction, 
    propertySet="Pset_WallCommon", 
    datatype="IfcLabel",
    uri="https://identifier.buildingsmart.org/uri/.../prop/LoadBearing", 
    instructions="Fire rating is specified using the Fire Resistance Level as defined in the Australian National Construction Code (NCC) 2019. Valid examples include -/-/-, -/120/120, and 60/60/60",
    minOccurs=1,
    maxOccurs=1)

my_second_spec.requirements.append(property)


my_ids.specifications.append(my_second_spec)

# Save such IDS to file
result = my_ids.to_xml(my_ids_path)

Really cool that with ifctester that is was possible to recreate the sample ids file !
