Create view source button to display SRS MARC Bib

Purpose: To be able to view the SRS MARC record from the related Inventory Instance

As a staff person
I want a button on the Inventory Instance record
So that I can easily see the underlying source MARC bib record that is linked to that particular Instance

Scenarios

1. Scenario 1
   • Given the Inventory Instance detail view
   • When there is an underlying MARC bibliographic record in SRS (Instance metadata_source = MARC)
   • Then display an option to view that source record in the Header action caret
     • MARCcat MARC bib icon (see attached)
     • Followed by the words View source
     • See attached screenshot View source button.PNG
2. Scenario 2
   • Given the Inventory Instance detail view
   • When there is NOT an underlying MARC bibliographic record in SRS
   • Then do not display the "View source" option in the Header action caret
   • NOTE: Let A-M know if this is a problem. This is preferable to greying out the option.
   • There's a bug, but I'll write it up separately
3. Scenario 3
   • Given the View source button
   • When a User clicks it
   • Open a full-screen view of the SRS MARC Bibliographic record as an overlay over the Inventory screen
     • Header
       • Top left: x button, so that it can be closed
       • Top center: The instance title, taken from the instance Resource_title field
     • Left justified: Source: MARC bibliographic record
     • Left justified: MARC record in human-readable form, from the Leader through the 999 field
     • NOTE: See attached View source button.PNG showing the previous, deprecated formatting
     • NOTE: Per OleksiiKuzminov, we can use MARC4J to reformat the MARC-JSON into a more human-readable display
4. Scenario 4
   • Given the View source overlay
   • When the user clicks the x in the top left corner
   • Then close the source record
   • And return the user to the Instance detail view
5. Scenario 5
   • Ensure automated testing coverage for this new code is 80% plus and confirm with screenshot
