SNPWG2

SNPWG has to develop a Product Specification enables ECDIS manufactures to built up a software able to display NPub information on an ECDIS screen. Following sub-pages provide discussions on the UML model and the ProdSpec for several NPub problems. The wiki administration is trying to provide the files in a convenient way; but we can not guarantee to fit all requirements.

We start the UML modeling with different UML applications and spotted several problems when trying to exchange the files. We decided to use StarUML as the common application. StarUML is free available and can be downloaded from the StarUML website http://staruml.sourceforge.net/en/. The file exchange works properly.

Product Specifications

Generals

Initially we tried to adapt the S100 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 S10x for NPubs and it is likely that such a specification can differ from S100. We also discussed two options of a NPub ProdSpec

1. a total new NPub ProdSpec starting from scratch
2. a NPub ProdSpec using S57 and charted content as much as possible, adding only those features relevant for nautical information.

The result is to follow the latter option. That avoid also some work for us because we haven't to develop the charted content again. How that works can also be seen at the UML models. Only features useful for SNPWG interests are copied from S57. All others remain untouched.

What is currently under discussion? Do we need to built several ProdSpec or can we combine all ProdSpec proposed below into one NPub ProdSpec. We will see what the future brings?

UML Models

I 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.
