NEW!!!
XID Authoring System Version 7.0

has been launched with enhanced user features!

 

 The Authoring System allows the user to create an identification program for any group of "items" or species (i.e. cars, minerals, molecules, insects, students, etc..)  The databases created can be supplemented by color images of each species and line drawings to illustrate the terminology used within the menus.

 

XID keys can be as simple or sophisticated as the author wishes, making this program as useful to junior high school teachers as it is to scientific specialists.  Such programs offer many advantages over traditional dichotomous keys. While originally produced to increase speed and ease of use, they also provide the ability to easily update the data and images, and are much cheaper to produce and more compact than hard copy guides. In general, much more data is included on each item/species than is necessary to identify it.  With this abundance of data, the user can identify any of the items/species using the characteristics most obvious and easy to describe. With each characteristic entered by the user, the program eliminates all species that do not have the combination of features entered.
