P_SINGLEVALUE
/
IfcIdentifier
|
 | Reference | Reference ID for this specified type in this project (e.g. type 'A-1'), Also referred to as "construction type". It should be provided as an alternative to the name of the "object type", if the software does not support object types and no classification reference to a recognized classification system used.
IFC4.3.0.0 DEPRECATION The Reference property is deprecated and shall no longer be used, use attribute Name on the relating type instead.

PEnum_ElementStatus |
| Status | Status of the element, predominately used in renovation or retrofitting projects. The status can be assigned to as "New" - element designed as new addition, "Existing" - element exists and remains, "Demolish" - element existed but is to be demolished, "Temporary" - element will exists only temporary (like a temporary support structure).
|
| 状態 | 要素（主にリノベーションまたは改修プロジェクトにおいて）の状態。 状態は、「新規(New)」－新しく追加される要素。「既存」－要素は存在し、かつ残りもの。「破壊」－要素は存在したが、廃棄されるもの。「一時的」－一時的に存在する要素（一時的にサポートしている構造のようなもの）。
