What is IDS?
The IDS (Information Delivery Specification) is an open buildingSMART standard that describes information requirements in a machine-readable way. Instead of stating requirements only in prose, IDS defines checkable rules: which elements must carry which properties, classifications and value ranges.
The IFC check
With an IDS you can validate an IFC model automatically: does each element meet the required attributes? The check shows passes and gaps — right in the browser, without your model ever leaving your computer.
The loop closes: EIR + LOIN order the information → IDS makes it checkable → the IFC check proves compliance. "Feels done" becomes objective evidence — essential for FM handover and acceptance.
Why it matters
- Objective acceptance — no argument about "done or not".
- Early error detection — missing data surfaces before handover, not in operation.
- openBIM — vendor-neutral via IFC, not tied to one tool.
In the tool
In the generator you create the LOIN, derive an IDS from it and check your IFC model against it — all in one flow, free to try.
