Proposal to extend class 004 Computer science by K. P. Singh

We have just received an interesting proposal for the extension of the UDC class 004 Computer science by Kunwar P Singh and Manisha Singh (Department of Library and Information Sceince, University of Delhi) - which we are looking forward to working on.

We have been annually updating class 004 ever since its major revision and publication in 1994, adding a couple of the most urgently needed concepts almost every year. Class 004, has over 850 records in the database. Some areas of 004, however, certainly need attention. Kunwar's proposal may be very helpful in updating the 004.4 Software part of the schedule, especially programming languages. What is also an excellent contribution is the subject-alphabetical index that we can also add to the UDC Master Reference File to improve searching.

I have recently looked into the BCS Taxonomy developed by Judi Vernau and I find the main separation of the field into academic and professional topics rather interesting albeit impossible to align with document indexing requirements. Anyway, UDC allows any other field of knowledge/application area to be related to 004 which obviously influences the basic structure and difference between a general knowledge classification and special classifications.

It is useful to note that we have selected the following subdivision of 004 to be published in the UDC summary:
