LongText : TShirt_Essay The effect of origin on TShirt quality is not well understood. Sarah (1990) notes that shirts made with Egyptian cotton are particularly durable. She mentions the infamous sam19 as a case in point. Vicki (1982) claims that shirts manufactured by Champion are now collector's items. ***LongTextEnd***When the hypertext feature is invoked, ACEDB identifies words that correspond to objects in the database and creates hypertext links to them. Suppose the essay above is in our database, perhaps linked to a TShirt. Also assume that other data, not detailed here, has been loaded:
KeySet : searchedClasses Class TShirt Class Person Class ManufacturerA KeySet object is used to list classes or objects in them.
[text window inline]
[longtext window inline]
[longtext with hypertext links]
Whether or not the hypertext feature is useful to you depends largely on the sort of documents you commit to LongText and whether or not they include object names. If your bibliographic references include abstracts, you might consider rendering the abstracts as LongText instead of Text or ?Text. If you are using LongText exclusively for user help, hypertext may not add much value. Remember that the user chooses to activate the links with the "search" button; if you decide to allow links, users are not forced to look at them unless they want.
ACEDB's implementation of hypertext is limited in two ways. First, all possible links will be made; if a Locus is called "and" or "are", these words will be highlighted in every LongText document, whether or not they are Locus names. You cannot "escape" individual links. Second, you can only link to a single object at a time. If you activate links to two classes, and there happens to be an object in both classes with the same name, you will link to only one of them. But even with these restrictions hypertext has the ability to make longish text entries much more useful.
