Listings provide a simple mechanism for organising information both by theme and by locality. The differences between a tour and a listing are
- A tour is an order sequence of stops, with additional linking information. The sequence and the linking information have to be input manually.
- A listing is generated automatically by using the tag information in individual pages. There is no need to specify which pages are in a listing.
- Tours are always presented as a list of titles. Listings can also be presented as a gallery of images. This is useful for more visual items and takes advantage of the fact that the listing is not ordered.
The main use for listings is to provide visitors with a larger view when they are looking at the page for an object. For instance, if the visitor is looking at a plant in a glasshouse a listing of all the plants in the same house can be useful. For example:
It is very easy for a visitor who sees a label to scroll to the correct entry for information. This is even simpler in many cases than using the keypad, and is helpful for the collection as it doesn't require a wholesale change in the labelling of items.
The other use of listings is to provide thematic information -- pictures by the same artist, or from the same school for example. In this case there are less likely to be many items, and pictures in the listing, or the listing as a gallery might be more appropriate to provide visitor's with context. When physical locality is not involved its also helpful for items to be available on a map so that the visitor can locate them physically.
To see how listings can be created we'll create an image listing for the tour we built in the last lesson. This is just to demonstrate the image styles of listing. The text style would be similar to the trail without the ordering of tour stops and the linking text.
Start editing the guide by going to the _Dashboard then selecting and editing your guide. When in the Settings page choose Listings from the left side menu. You will see
Hit the + button to add a new listing. You will see
The Id is used in links. We'll call this one trail. The tag is also trail. This will select all pages which contain the tag trail. Our three pages do contain this tag. Here is the filled-in page.
If you now publish the site you can see links to the listing on pages with the trail tag.
The listing page itself is an image gallery.
Note that contrast is not very high. Image listings are most suitable for indoor areas where the light is not very bright.
In the next tutorial we look at creating an embedded shop.
