1. Since the functions of Folders in early releases have been taken place by Categories Modules, Categories Module is becoming the the center piece for information management in the newly released Biblioscape. Now a record (reference record, notes record, task record or chart record) can belong to one category and even more. I suggest that the Data type of Categories field in the tables which store reference record, notes record, task record and chart record should be changed from "String" type to "Memo" type. The "String" type can only contain 200 characters, maybe it is not enough for some users. And I found that the Biblioscape application added extra "_" at the beginning and the end of each category name in the Categories field of the record. So the application will add 4 extra characters in the Categories field( which include the delimited symbol "; ") everytime when users add a category name to a record.
2. The size of Categories field in reference record is 100 bytes(bib.dat) while the size of Categories field in other record (like notes and chart record ) is 200 bytes(note.dat, chart.dat, etc.).
3. Since Category can also be organized in tree struction, will it result in confusion if there are two sub-category which have the same name? For example, in the Catogories tree there are two root nodes named "actors" and "scientists" respectively, they both have a child node named "biography". If you add a reference record and let its category belong to "biography" (which is the child of "scientists" ). then you can find the newly added reference record also belong to "biography" (which is the child of "actor") in the Categories Module. So I think the Category ID field should be taken into account.
sample Categories tree:

One possible answer to the scenario you outline in in question 3. would be to have a single category for "biography", but then you would need to be able to generate a list of references that are in the category "scientists" AND the category "biography." Is this possible???

A taxonomy built with the
A taxonomy built with the categories module should use linking to represent knowledge. If it is for tagging, the term should then be unique. Tagging means adding a bunch of terms to describe an information object. It is like the keywords field. You cannot use the same term twice even it means different things.

Right, so in the example we are working with would you suggest making "biography" a keyword? Then you could combine a category search with the key word to get the right reference set?
If I build a taxonomy for
If I build a taxonomy for tagging, I will make sure each term is unique. I will have one term "Biography Scientist" and another one "Biography Actor". Actually, a taxonomy like the one given should not be used for tagging. In that example, the relationship between parent and child is many-to-many. It is better to use faceted classifications. I will have one facet "Professional", under it there are "Scientist", "Actor", etc. I will have another facet called "Writing", under it ther are "Biography", "Interview", etc. When you use this for tagging, you can add one tag "Biography" and another tag "Scientist". In Biblioscape 7.x, when you have more than one category selected, Biblioscape will build a search with "AND" operator. When building a tree strucutre, a child should not have more than one parent.

Ok, I'm starting to get this. Thanks. Is there a way to add a pop up in the advanced search so that when you add "categories" as the field, you get a pop up in the "value" that would allow you to choose the categories instead of having to type them in?
After you do a fast search,
After you do a fast search, click the refine fast search icon. You can then pick a category from a list and add more conditions.
1, 2. Good points. I agree
1, 2. Good points. I agree with you.
3. Categories can be used for both tagging and linking. When you use it to build knowledge base, you should use linking instead of tagging. With linking, Biblioscape will points to the correct record even they have the same name.
Thanks,
