NIPWG is developing Product Specifications to enable ECDIS manufacturers to build software able to display NPUB information on an ECDIS screen.

This Wiki attempts to provide the files in a convenient way; but we can not guarantee to fit all requirements.

Published and in-progress Product Specifications

Currently (September 2022), the following Product Specifications are under development:

S-128, Catalogue of Nautical Products Edition 1.x
S-131, Marine Harbour Infrastructure Edition 1.0.0

The following Product Specifications have been published as of September 2022 and are available from the IHO Geospatial Information Registry, Product Specification Register.

S-122 Edition 1.0.0
S-123 Edition 1.0.0
S-127 Edition 1.0.0
S-128 Edition 1.0.0

-Initially we tried to adapt the S-100 ProdSpec as much as possible. That was good for the learning process.
-However, we have had a discussion resulting that we have to develop a ProdSpec S-10x for NPUBS and it is likely that such a specification can differ from S-100.
-We also discussed two options of a NPUB ProdSpec
-# a totally new NPUB ProdSpec starting from scratch
-# a NPUB ProdSpec using S-57 and charted content as much as possible, adding only those features relevant for nautical information.
-The result is to follow the latter option. That avoids some work for us because we do not have to develop the charted content again.
-How that works can also be seen at the UML models. Only features useful for SNPWG work are copied from S-57. All others remain untouched.
-What is currently under discussion? Do we need to build several ProdSpec or can we combine all ProdSpec proposed below into one NPUB ProdSpec. We will see what the future brings?
-===Waterways===
-The waterway ProdSpec is being discussed between Olav and Jens. The files reflecting the discussions are stored here [[Image:Product_Specification_Waterways.doc]]

-==UML Models==
-We propose to display a jpg. file providing a preview of the UML model here or at the sub-pages and a link to the uml file for those who intent to work with UML.
-Discussions are to be placed to the discussion page which has a similar structure like this page. The contacts provided are hosting the UML diagrams. It is strongly advised to contact them before trying to amend the attached UML files. The e-mail addresses are to be obtained from the IHO/SNPWG website if not known. We intent to avoid too much duplications of the work done.

-The diagram needs revision checking if the associations/aggregation are been set correctly.
-However the idea behind the diagram is simple now.
-Waterways (for SNPWG interest) are navigable. That means they should have at least a SEAARE object to provide an OBJNAM. Furthermore the SEAARE needs some Category 1 objects to cover the skin of the earth, means DRGARE, DEPARE or UNSARE. All other objects are using the three object to describe the navigable water.
-If non-geo objects apply in one area either the SEAARE or the other non Cat 1 objects they can be easily added. Using  non-geo objects at the cat 1 objects is also possible.
-ARCSLN is not been considered yet.
-This diagram was revised several times enabling us to get the ProdSpec displayed in UML. The results are listed.

-The UML file for the pilotage model depicts attributes,
-enumerations, etc. in diagrams separate from the main diagram.
-Also, there are some omissions and shortcuts in
-this diagram, for example, ordinary UML enumerations are not quite the
-correct model for S100 enumeration value lists (doing that correctly
-in UML will take a lot more effort and complication and at this point
-of time I am not even sure StarUML can show it properly).  The objects
-and attributes in this version are Jeppesen proposed updates (as of July
-) to those on the Wiki.
