How does this work?

You may want to read some background to know what this is all about. All source files are available from that page.

The green brackets in the text, and the green outlines in the picture, show the presence of encoded sign fragments. In the texts, placing the mouse over a left bracket will tell you something about the text fragment: it will give its internal identifier and tell in what lowest-level signs the text fragment is used. In the image, alt texts will do something similar.

Clicking the mouse on a right bracket, or somewhere in the picture, will take you to the sign model page. You'll be shown a diagram of the current text or image fragment hyperlinked to other signs and sign classes.

In the selection lists in the right bottom corner you can select a sign class, and then either:

• list the corresponding sign instances in the sign selection list;
• highlight all instances in text and/or image (this will highlight the sign vehicles rather than the signs themselves, of course);
• view a diagram of the sign definition.

The sign selection list has similar functions.

I am very much interested in your feedback.
