Purpose of this story is to Update Marc2BF conversion Java library to process marc field 008, char 18-21 to create “illustrations” edge.
This conversion is applicable only when the material type of the Work is “Book”. Determination of the material type should rely on examining characters at positions 6 and 7 of the leader (0-based indexing). If the combination of characters in positions 6 and 7 of the leader matches any of the following sequences, then it is recognized as a Book.
Each Work may contain multiple illustrations, denoted by characters within the range of 18 to 21 (inclusive). A Category resource is to be created for each character.
New resources to be created
Resource 1:
For each character within the range of 18 to 21 (inclusive), specifically if the character is one of: a, b, c, d, e, f, g, h, i, j, k, l, m, o, or p, an outgoing edge with predicate http://bibfra.me/vocab/marc/illustrations should be created from the Work resource.
a - Illustrations b - Maps c - Portraits d - Charts e - Plans f - Plates g - Music h - Facsimiles i - Coats of arms j - Genealogical tables k - Forms l - Samples m - Phonodisc, phonowire, etc. o - Photographs p - Illuminations
In scope: Conversion from MARC to linked data
Out of scope: Conversion from linked data to MARC (MODLD-365)
Notes:
95,659 monographs in LC’s 1M dataset has “illustrations”
