An ECLASS MajorRelease is a release type that includes all possible modifications of existing structural elements (including structural modifications) and the addition of new structural elements, as well as modifications of the relations between existing structural elements. More information on the MajorRelease can be found here.
The ECLASS maintenance process is based on ISO requirements and similar to the maintenance process of other standards as e.g. the DIN property server. To facilitate the development of the standard for every interested user, the ECLASS ContentDevelopmentPlatform (formerly knows as ServicePortal) was developed as an online platform to give every user the possibility to submit change requests for the standard. The ECLASS association distinguishes three different types of releases that will be described in the following section. In 2021, the ECLASS board decided to only publish Major Releases from Release 12.0 onwards.
An ECLASS MinorRelease was a release type that included the modification of certain attributes of existing structural elements (e.g. textual changes) and the addition of new structural elements, as well as new relations between new and/or existing structural elements. More information on the MinorRelease can be found here.
