No :) We use a.... "unique" system here at GE. The bottom portion is created automatically by the Item's template, using information from other files which place pages into hidden categories. We use DPL to have it build links showing that category's data. In the 'Recipes using Flannel' section, for example, if you go to http://ffxiv.gamerescape.co... you'll see that Flannel is listed as "Ingredient 3". That code being on that other page is all that's needed to make our system automatically show that Flannel is used in that recipe, on this page.
Same thing with the 'Acquired from Duty' section up above. Flannel comes from The Aquapolis, so in The Aquapolis's page is a section showing the rewards, and Flannel is listed there.
Each item's template is coded to look in a number of different categories and told to automatically data on the item page depending on what it finds. As you can see in http://ffxiv.gamerescape.co... for example, there are 4 recipes that use Flannel (4 pages, and then the /Recipe subpage which is ignored for the purposes of displaying the links). You'll see that those 4 pages on that Category page perfectly match what the "Recipes using Flannel" section up above shows :D
Depending on what you want to add, you'll have to go about it in different ways. Sadly that's one of the things we're lacking a bit of documentation on.. T_T It's on my list of things to do!@ (eventually..)
All this done to save ourselves the trouble of keeping track of what item's stats (cost, parameters, npcs who sell it, quests its involved in, etc) so we don't have to manually change 50 pages every time one of the item changes somehow. The system does all of that automatically for us!
