Mapping of Subject Field
Mapping table
NASA STI
NCSTRL+ Subject
The Algorithem used in Subject Field mapping.
- get the NASA STI NO, this should be XX or XX-XX format.
- get the NCSTRL+ top level subject by the STI NO. Most of them are perfectly same, except
the MATHEMATICAL AND COMPUTER SCIENCES field in STI. In ncstrl+ they are seperate. Now I
use Computer Science, this will result in all the mathematical is mapped to
Computer Science. Now we get some format such as NCSTRLPLUS-ARCHIVALTYPE::
Aeronautics
- get the NCSTRL+ detail level subject by search the mapping table. if find, append the
detail level subject to the archivaltype field, such as NCSTRLPLUS-ARCHIVALTYPE:: Aeronautics/Aerodynamics.
If not find , do nothing.
- If the mapping table is perfect, we can get the perfect result by this method. Now the
mapping table is just a simple test.
