The eCl@ss association has defined certain rules and regulations and relies on certain national and international standards. These rules can be assigned to different categories:

• Technical standards (e.g. such as the data model or identification scheme)

• Content rules (e.g. branch-specific standards or rules for the creation of certain structural elements)

• Process standards (such as the eCl@ss maintenance process)

Harmonized Branch Standards

eCl@ss relies on existing branch-specific standards rather than re-inventing what has already been created by experts. Therefore, eCl@ss cooperates with various other classification authorities in order to make eCl@ss interoperable to branch solutions, as all of them have the same goal: to promote eBusiness solutions. eCl@ss has already finalized harmonization projects with the following related standards:

Process standards

As described in the Release Process, eCl@ss relies on an international maintenance process as defined in the [ePPS project ftp://ftp.cen.eu/CEN/Sectors/List/ICT/CWAs/CWA16100ePPS.pdf] by the [CEN Workshop eCAT http://www.cen.eu/cen/Sectors/Sectors/ISSS/Workshops/Pages/eCAT.aspx].

The process is also related to the process used in the [DIN property server http://www.dinsml.net].
