\n\t\tWhat is IDS?\n\t<\/h2>\n\t\t\t\t\"IDS-logo1.1\"\n\t

Information Delivery Specification (IDS) is a buildingSMART standard for defining information requirements in a computer interpretable form. It allows for automatic compliance checking of IFC models, that increases quality control and fidelity of data. IDS also aids the efficient delivery of the data, by setting the expectations and providing clear guidelines of what needs to be exchanged. A user of IDS can specify how objects, classifications, materials, properties, and even values should be delivered in an IFC model.<\/p>\n\tPrevious versions<\/b><\/a>
\nAll the versions of IDS prior to 1.0 are not an official standard.\n\tIDS 1.0<\/b><\/a>
\nOn 1st June 2024 the IDS has been approved and became the official buildingSMART standard!\n\tFuture versions<\/strong><\/a>
\nWe are collecting feedback on the improvements needed for the IDS 1.1 and 2.0 versions.\n

\n\t\tIDS example\n\t<\/h3>\n\t
Human-friendly \ud83d\udc53<\/strong><\/h5>\n\t

All walls<\/strong> should have the property FireRating<\/strong> in the set Pset_WallCommon<\/strong> with a value being one of REI30<\/strong>, REI60<\/strong>, REI90<\/strong>.<\/p>\n\t

\n\ud83d\uddf7<\/strong> 2\/10 walls don’t have a FireRating property.
\n\ud83d\uddf7<\/strong> 1\/10 wall has a FireRating, but the value is “REI_60” which is not allowed.\n
