Note: This ticket was originally created as a a bug ticket. During 07/03’s daily, it has been decided to convert this to a story ticket.

Scope:

The subfields $v, $x, $y, and $z of MARC tags 600, 610, 650, 651, and 655 are repeatable. Currently, the mar4ld library only considers the first occurrence of these subfields when creating "subFocus" edges from the Concept resource, except for the four subfields listed below. The purpose of this ticket is to update the mar4ld library to account for repeating subfields when creating subFocus edges.

For each repeating $v, a subFocus edge should be created from Concept to a Form resource.

For each repeating $x, a subFocus edge should be created from Concept to a Topic resource.

For each repeating $y, a subFocus edge should be created from Concept to a Temporal resource.

For each repeating $z, a subFocus edge should be created from Concept to a Place resource.

Currently handled repeating subfields, as implemented in MODLD-287:

• 650$v

• 650$z

• 655$z

Description of the original bug created by @Yury Barsukou

Steps
1) Log in to Marc authority
Create a record with 010 and 100 fields
100 field should have duplicated fields (for example: $a 100a12 $b 100b $c 100c $c 100c2 $d 100d $j 100j $j 100j2 $q 100q $v 100v $v 100v2 $x 100x1 $x 100x2 $y 100y $y 100y2 $z 100z $z 100z2)
Copy ID of created recourse
Perform GET {{host}}/graph/resource/recourse_id
Check that http://bibfra.me/vocab/lite/subFocus has 1 ID for each $v, $x, $y, $z fields (including duplicates)
2) Log in to Inventory
Create new record using 245 and 600 line, 600 line should be absolutely the same as in 100 line from marc authority
Copy ID of created work
Perform GET {{host}}/graph/resource/Work_id
Check that ID of http://bibfra.me/vocab/lite/subjectin outgoingEdges = Recourse ID from p.1
Check http://bibfra.me/vocab/lite/subFocus

AR
Additional records are created for each $v, $x, $y, $z with duplicate values
If you perform GET {{host}}/graph/resource/additional_record
it will include both values, $x 100x1 and $x 100x2 for example
Check the creens

ER
No additional records/ids should be created
http://bibfra.me/vocab/lite/subFocus should consist only records that were created in Marc authority
Each record should consist only 1 value of $v, $x, $y, $z subfields or their duplicates
