                                       Chinese KOS (Ⅱ): Research and implementation of Classification Scheme Sharing Service System


               with the base number from the schedules and notations from the subdivision tables by computer
               programs. Taking Table 2 for example, operation steps of number building are shown in Figure 3.
               Computer programs automatically calculate the accurate combined class numbers according to
               subdivision regulations. And the same results can be got through invoking Web Service APIs.
               The Web versions of DDC, LCC and UDC all provide number building functions. At present, the
               Web version of CLC v5.0 of the NLC does not provide the function yet. Compared with the Web
               versions of international mainstream classification schemes, it started late, but the possibility of
               providing the functionality of building new class numbers with the existing class numbers for users
               in the future should not be excluded.

                                                  The folk arts and crafts→TS938. The main
                                                  table doesn’t specify adding subdivisions from
                The Uygur   The folk arts   Uyghur  Chinese Nationality Table. But when needed to
                folk arts and  and crafts   nationality  be subdivided with the table, we need to add “2”   TS938“215”
                 crafts                           which is the notation for Chinese nationality in
                                                  front of “15” which is the notation for Uyghur
                                                  nationality. The result is “215”

                                                  Literature in various countries→I3/7.This
                                                  book is the comment on American modern
                                                  poetry, so adding notation from the Global
                Anxiety of                        Area Table at first, then subdivide using the
                 influence: a  Literature in   American  specific subdivision table for I3/7. The class   I712.072
                theory  of poem  various countries   poetry  number after subdivisions is I712.072. The
                (America)                         notation 712 represents America in the Global
                                                  Area Table and the notation 072 means poetry
