Classification MicroMVD

The following MicroMVD vocabulary can be used to ensure classification system standards are correctly applied.

For guidance on what values should be filled in for standardised classification systems, refer to IFC classifications.

Feature: Classification

For BIM objects to be filtered and categorised in facility management system
As someone who needs to catalogue BIM data in a structured and organised manner
Classification systems data must be assigned to each relevant element

Scenario: The appropriate classification systems are referenced in the model
 * The classification "{name}" must be used
 * The classification "{name}" is published by "{source}"
 * The classification "{name}" is the edition "{edition}" on "{edition_date}"
 * The classification "{name}" has the description "{description}"
 * The classification "{name}" is referenced by the website "{location}"
 * The classification "{name}" has a hierarchy denoted by the tokens "{tokens}"

Scenario: The relevant elements are assigned to the classification system
 * The element "{guid}" is classified as a "{identification}" with name "{reference_name}"

Note that for IFC2X3, the following rules will not apply, as the data cannot be stored in IFC2X3.

 * The classification "{name}" has the description "{description}"
 * The classification "{name}" is referenced by the website "{location}"
 * The classification "{name}" has a hierarchy denoted by the tokens "{tokens}"

You can fill out the variables using the guide below.

Variable	Example	Description

`{location}`	https://toolkit.thenbs.com/articles/classification	The official website to refer to the classification online, taken from the standard list if it exists.
`{tokens}`	["_"]	A JSON list of of all of the separating tokens which denote hierarchy in the classification system, taken from the standard list if it exists.
`{identification}`	Co_20_10_60	A single classification reference identification for the particular classification system, taken from the standard list if it exists.

ArchiCAD		ArchiCAD 23	Some work is required to set up the export, but it is possible. However, the description, location, and reference tokens for the `IfcClassification` cannot be exported. It should also be noted that the Graphisoft classification XMLs tend to store the location data in the source field, which is incorrect.
