We've identified a provisional basic list of categories (click here) but these are just that, provisional, and more can be added at any time. Some but not all of the categories have been split into possible sub-categories, feel free to add your own (eg "Plays by Ibsen" to the Plays category, or "deep sea diving" to the Hobbies category).
Many keyword lists have already been created, and certain topics have gained a listing of their own, eg Invertebrates has five lists but a sub-section of Invertebrates, "Insects", has nine lists of its own, and is identified as a separate topic because not all children would think to look for Insects in the Invertebrates category.
What we're also aiming to do is to make the lists as globally-relevant as possible - eg "Reptiles" has a number of snake lists, covering snakes from all over the world, because the children using the wordsearches will be from many different countries.
Eventually we will have a great many wordsearches - probably around 1000 in total, interlinked wherever relevant. And also leading off to other Internet resources - eg the Beatrix Potter listing within the "Books" area leads off to a site where kids can go and read beautifully-illustrated versions of these books *on line* .
But more than this, the "common frame of reference" identifies potential "areas to cover" to help ensure that any child can cover the basics of the general knowledge possessed by most teenagers and adults with an average education.
The "interests/crafts/hobbies" areas are just that, to provide basic structured keywords and vocabulary relating to specific areas of interest, eg "knitting" could be split into types of stitches, types of wool etc. - or we could create a "trades" section where a decorator, plumber, electrician or carpenter could send in lists of words related to his trade, such as specific tools used, types of wood, types of bathroom fitments, types of paint - and so on.
