raphael 21:45, 4 January 2013 (UTC): Continuing the remarks about commercial companies, satellite images, and commercial companies on the main page:

Adding satellite images as a source sounds reasonable. Adding commercial companies as a source is also reasonable but I think the term itself needs more thinking about in the context of the other categories (specifically, I'm thinking about classifying satellite data supplied by a commercial company).

"Information from the internet": We can make this "industry publications" and define it as "shipping and other industry publications and web sites".

One possible resolution of the question of law versus regulation is to combine the two into one term, e.g., make item 3 "national law or regulation", defined as "legislative or administrative law or regulation passed by a national government or national regulatory agency or authority". This has the advantage that the encoder or mariner does not have to think about the difference - unless the group believes the distinction matters to the mariner?

jens 09:38, 4 March 2013 (UTC) Should we extend the "publication" definition to include images/photographs/graphics? That would simplify the set of attributes for GRAPHC.

raphael 20:26, 4 March 2013 (UTC): I agree that graphics and charts should be included in the definition of "publication". The rest are fine, only insert "legislative and administrative" in the definition of item 5 (that is, make it like item 3 so no one wonders whether that difference is significant).
