Is there terms in IFC corresponding to construction specifications ? And if there,where can I find it?
The heading should be Freeware not Free Software. Could one of the wiki administrators change this I am a newbie at ifcwiki.
Freeware (from "free" and "software") is computer software that is available for use at no cost or for an optional fee, but usually with one or more restricted usage rights. Freeware is in contrast to commercial software, which is typically sold for profit. The term does not imply that the software is free and open source software (FOSS). Freeware is a loosely defined category, which includes both closed and open source proprietary software.
Free Software and Open Source Software are different names for exactly the same thing.
