Question; would it be possible to completely clear all items from the wiki, then on all item tool tips and in the ship window have an "Add to Wiki" button. No items could be added outside of this system, and all items added would be kept updated by the server once a player chooses to add them (potentially updating the wiki with fresh stats every time the server restarts).

It's possible, but my general plan was to implement a system where items are added to a database when they get picked up my market check for the first time. This could then be by some front end that wasn't going to be the wiki. Someone could also use it to update the wiki, though.

Wiki is somewhat limited, and the design we have will allow players to access the raw data in a format suitable for processing in programs for their own purposes (such as building calculators).

This way we also get MC data.
