Notes and Terms related to building a product specification

In an effort to transition from paper-based books to a more data-centric information system, these product specifications were decided by the group. The information stored in N-Pubs were broken into manageable thematic information blocks that could be assigned to individuals within the group who are subject-matter experts.

The following pages contain discussion and work being done on each specific product specification (an * means there is no sample data so the page is rather empty, highlighted are being "intensively worked on"):

S-122 - Marine Protected Areas

S-123 - Radio Services

S-124 Navigational Warnings*

S-125 - Navigational Services

S-126 - Physical Environment

S-127 - Traffic Management

S-128 - Catalogue of Nautical Products*

S-12x - Marine Services*

S-xxx - Digital Mariners' Routeing Guide*

S-xxx - Harbour Infrastructure*
