Link Class (LNCLAS)
Classification of documents is possible through use of Link Classes (LNCLAS). Each Link Descriptor (LNDESC) may be classified by multiple classes; in the diagram below see how each LNDESC is associated with more than one LNCLAS. A single Link Class may classify multiple Link Descriptors; in the diagram LNCLASI is associated with all three LNDESC.
A Link Class has the following attributes:
•
NAME - user-defined name of the LNCLAS element.
•
DESC - description of the element.
There is also a pseudo attribute available named LNKDOC that returns a list of LNDESC elements that are classified by this LNCLAS.
