This is the start page for NIPWG Feature Concept Dictionary discussion.

A source providing S57 the Feature Object Catalogue is listed at the menu bar for your convenience.

READ THIS FIRST The open issues have been placed at the "Proposed ... to be added to NIWPG FCD" menu items. If you agree with the proposal add your name/organisation and a little "agreed" just underneath the separation line which can easily be detected by the four "-" at the bottom of each page when switching to "edit" modus. This "edit" can only be seen when being logged in.

This procedure applies only to the open items. However, the discussion is not limited to them.

Use of different colours to specify the different status of FCD entries

The menu entries should use different colours to show their status of implementation
"black" means not approved by a Product Specification
"blue" means confirmed
"red" means added to relevant IHO register

All menu entries are enhanced with the relevant html code. It is only necessary to change the colour according to the given values.
