In scope: Conversion from MARC to linked data

Out of scope: Conversion from linked data to MARC

Notes:

• 105,049 monographs in LC’s 1M dataset has “supplementaryContent == Index”

• Example RDFs having supplementaryContent derived from 008:

  • https://id.loc.gov/resources/works/21186195.rdf

Overview:

Purpose of this story is to Update Marc2BF conversion Java library to process marc field 008, char 31 to create “supplementaryContent” 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.

New resources to be created

Resource 1:

if char 31 of 008 is “1”, an edge http://bibfra.me/vocab/marc/supplementaryContent should be created from the Work resource.

Type: http://bibfra.me/vocab/lite/Category

Resource 2:

 Create an outgoing edge http://bibfra.me/vocab/lite/isDefinedBy from the Category resource with the following properties
Type: 
 >> http://bibfra.me/vocab/lite/CategorySet

Properties

Example:

Consider the below given 008 value, where characters in position 31 is “1“

200104s2018 tu ac b 001 0ctur d

The resulting graph should resemble the following:
