This is one way of doing, although it is not always desirable to have
the full ISO list for everyone (this is why there is no default category
in ERP5).
I would suggest to put a link to this list in the erp5.org (it is maybe
already there).

This area:
    http://www.erp5.org/ResourceLibrary
is meant for that.

In some cases, we have set a workflow on categories to define which are
in use and which are not.

By using the checked_permission or state parameter, we only display
those categories which are still in use, while preserving legacy data.

This way, it is possible to keep old category definitions and introduce
new ones during the life of the system, without doing heavy data migration.

The reason why this workflow is not set in default is because the more
workflows in the system, the less performance. It is also possible to
achieve similar result by changing effective data parameters in categories.

JPS.
