23 Religions originating in Indian subcontinent
24 Buddhism
25 Religions of antiquity. Minor cults and religions
26 Judaism
27 Christianity
28 Islam
29 Modern spiritual movements

11. Research Question
Can we use UDC’s Class 2 as the framework for an alternative view of religion in the DDC and a model for future revision of 200 Religion?

12. Project: Stage 1 Develop top-level crosswalk for major religions
Develop detailed crosswalk using Buddhism as case study
Use initial findings to plan for Stage 2

13. DDC View Based on UDC (excerpt)
Taoism ( )
Confucianism ( )
Hinduism (294.5)
Jainism (294.4)
Sikhism (294.6)
Buddhism (294.3)
Wicca (299.94)
Yoruba (African people)—religion ( )
Voodoo ( )
Ras Tafari ( )
Bible (220)
Judaism (296)
Christianity (230)
Islam (297)
Scientology ( )

14. Buddhism Case Study 1: UDC 24 + DDC notation
DDC Buddhist mythology = 243.3
Moves to chronological position
Retains DDC number building and internal/auxiliary tables
Meaningless notation in either system
Retains limited development

15. Buddhism Case Study 2: Detailed Mapping

16. Findings Structural differences and inconsistencies in both systems
Differences in enumeration/synthesis
Differences in main religion auxiliary table
Differences in common auxiliaries

17. Project: Stage 2
Map general religion topics at facet level

18. Facet Mapping 202.2 Humankind 2-18
Including atonement , creation of humankind , repentance ,
salvation , sin ,
soul
Class here comprehensive works on karma 2-182
. . .

19. Project: Stage 2 Map general religion topics at facet level
Map branches, divisions, sects
Test top-level browser
Map Islam at detailed level in conjunction with UDC expansion and DDC Arabic translation

20. Summary and Recommendations
Framework based on UDC’s Class 2 is feasible as optional arrangement, browser, and future structure for 200 Religion in the DDC
Initial UDC Class notation can be used to reposition corresponding religions in the DDC
Mapping topics in religion at the facet level will result in improvements to DDC and UDC, and will foster interoperability between the two systems
