The subject of the work needs to be supported in the Marva editor for cataloging workflows:

The subject component in BIBFRAME is mapped to multiple tags in the corresponding MARC record as detailed in , , , .

The scope of this card will be limited to displaying the values of the subject components in resource descriptions derived from MARC records. As a first step in building out support for subject headings, this card simply requires read-only display of the labels returned in the API contract.

For now, the value(s) of the subject should be displayed in the Marva interface alongside 'Search LCSH/LCNAF'

• $a of subject fields (600, 610, 650, 651)

Out of scope

• Any/all subfields besides $a in fields 600, 610, 650, and 651

• The ability to search / lookup values for the subject component

• "Qualifiers" defined in the Monograph profile, but not present in the corresponding MARC record:

  • Subject components (e.g. Geographic subjects, Children's subjects, Work as subject)

  • Subdivisions (e.g. Heading or Topical, Geographic, Chronological, Form)

Each of these will be addressed in separate Jira cards

Use cases

1. Concept / [Family / Person]

GIVEN that a cataloger has conducted a search for resource descriptions in Marva

AND the underlying MARC record has a subject in the 600 tag

WHEN the cataloger chooses to see the full display of a resource description from the search results list

THEN the resource description is displayed

AND the subject component is populated with the same value as in the $a field in the 600 tag in the corresponding MARC record

2. Concept / [Organization / Jurisdiction]

GIVEN that a cataloger has conducted a search for resource descriptions in Marva

AND the underlying MARC record has a subject in the 610 tag

WHEN the cataloger chooses to see the full display of a resource description from the search results list

THEN the resource description is displayed

AND the subject component is populated with the same value as in the $a field in the 610 tag in the corresponding MARC record

3. Concept / Topic

GIVEN that a cataloger has conducted a search for resource descriptions in Marva

AND the underlying MARC record has a subject in the 650 tag

WHEN the cataloger chooses to see the full display of a resource description from the search results list

THEN the resource description is displayed

AND the subject component is populated with the same value as in the $a field in the 650 tag in the corresponding MARC record

4. Concept / Place

GIVEN that a cataloger has conducted a search for resource descriptions in Marva

AND the underlying MARC record has a subject in the 651 tag

WHEN the cataloger chooses to see the full display of a resource description from the search results list

THEN the resource description is displayed

AND the subject component is populated with the same value as in the $a field in the 651 tag in the corresponding MARC record

5. No Subjects

GIVEN that a cataloger has conducted a search for resource descriptions in Marva

AND the underlying MARC record does not have values for the 600, 610, 650, or 651 tags

WHEN the cataloger chooses to see the full display of a resource description from the search results list

THEN the resource description is displayed

AND no values are displayed in the subject component

6. Multiple Subjects

GIVEN that a cataloger has conducted a search for resource descriptions in Marva

AND the underlying MARC record has multiple subjects (spanning the 600, 610, 650, and/or 651 tags)

WHEN the cataloger chooses to see the full display of a resource description from the search results list

THEN the resource description is displayed

AND each subject value is displayed in the subject component

7. Repeat --> Edit mode

Use cases 1-6 apply when viewing a resource in edit mode.
