3. Presentation structure
What is mapping of vocabularies?
What we have done so far: The first project period
What do we achieve when mapping?
What next: The second project period
Mapping is quite a challenge!

5. What is mapping?
Mapping means to establish relationships between concepts in two different vocabularies

12. Methodology for mapping

13. Methodology for mapping
● ISO Interoperability with other vocabularies
● EDUG’s recommendations for
best practice in mapping involving Dewey Decimal Classification (DDC)
● Policy statement for the project
“Mapping to Norwegian WebDewey
at the University of Oslo Library”

15. The need for a mapping software
Mapping as a computer-assisted intellectual process
From proof of concept to fully developed web application thanks to cooperation with Pansoft
Started using the tool in January 2017
Mapping, import/export and update management
Why we needed ccmapper •       Mapping, intellectual process, supported by automatic suggestions, need for a mapping software.  •       This software should support mapping on the concept level  •       Support the kinds of concepts we have and display and use all relevant data such as synonyms, hierarchy •       tool that would allow us to update and edit our mappings  •       changes in both the source vocabularies and WebDewey  •       search for lists and overview of mappings, and find concepts to map •       We reached out to pansoft on the edug meeting two years ago, resulted in collaboration
Behov for ccmapper •       Mapping er en intellektuell prosess men kan lettes av datastøtte •       Opprette mappinger •       En mapper og en kontrollerer •       Endre/vedlikeholde mappinger •       Oppdage endringer i vokabularene som påvirker mappingene •       Oversikt over eget arbeid (lister)

37. Summing-up of Two mapping project periods

38. Summing-up of Two mapping project periods
Mapping to Norwegian WebDewey
Methodology for mapping: EDUG recommendations based on ISO part 2
Mapping software: ccmapper with Pansoft
Start mapping of our two subject vocabularies
Mapping for end users
Explore the end user perspective in subject search
Develop prototype for improved subject searching
Complete mapping of two subject vocabularies

39. Primary focus: Mapping for end users
● Improved topical searching across collections and languages
● Making use of topical metadata (including mappings) before search onset
● Interactive help during the search process
