Model for populating 650 - subjects #1744

Closed silveroliver closed 6 years ago

silveroliver commented 6 years ago

Our use of subject was inpart inspired by Library of Congress. Though note ComplexSubject is not from Bibframe but is from another LC spec called MADS for representing authority records (acknowledging holes in SKOS in its ability to handle post-coordination).

Example:

{
  "subjects": [
    {
      "label": "Tuberculosis - prevention & control -- Paris -- 1850 -- bibliography.",
      "type": "Subject",
      "concept": {
        "id": "hd2891f",

    }
  ]
}

Looking for alternatives to "topics".

This work is about Tuberculosis and...

"topics" : "prevention & control" or "generalDivisions": "prevention & control" or "generalQualifiers": "prevention & control" "generalConcept": "prevention & control" "generalSubjects": "prevention & control" "furtherQualifiers": "prevention & control" "qualifiers" : "prevention & control" "divisions" : "prevention & control" "descriptors" : "prevention & control" "generalQualifiers": "prevention & control"

The more I think about this, the more I'm coming round to calling concept primaryConcept and topics secondaryConcepts. In an attempt to describe both the relationship from Subject and between the concept and general devisions.

I’ve been looking at mads/skos and how Oslo Public Library deal with 650. Oslo public library don’t catalogue anymore using marc records/use minimal marc records:

https://summit2017.lodlam.net/2017/04/12/oslo-public-library/

https://github.com/digibib/ls.ext/wiki/System-components-overview

Use of broader/narrower concepts looks popular… I am attempting to write some code using a narrower topic concept…

Mads example:

Computer programming Computers Programming languages Systems Analysis

Oslo library example: http://data.deichman.no/subject/sjakk a skos:Concept ; (Main topical term: Chess) skos:narrower http://data.deichman.no/subject/x16878200 ; (Chess – Periodicals) skos:narrower http://data.deichman.no/subject/x12784600 ; (Chess – Endgame studies) skos:narrower http://data.deichman.no/subject/x12961800 ; (Chess – Problems) skos:narrower http://data.deichman.no/subject/x15398200 . (Chess – History)

Thought I'd carry on and throw this into the mix - I've made some new terminology suggestions often more than one for each term...

  1. For all bibliographic records use "marcTag": "650".
  2. If more than one subfield is populated. Populate platform "label" with concatenated subfields v, x, y, z in order, seperated by a double hyphen ' -- ' and type as "WholeConcept" or "EntireConcept" or "FullConcept".
  3. If only "a" subfield is populated type as "MainConcept" or "MainSubject" or "MainTerm" or "MainTopic".
  4. Populate platform "concept" "label" with subfield "a".
  5. When this concept has associated identifiers populate "authority" with value form subfield 0 and identity scheme from second indicator (0=lcsh 2=mesh) or if indicator 7 look at subfield 2 and populate "authorityScheme".
  6. For each subfield, for subfields v,x,y,z populate "related" with a "label", type "NarrowerConcept" or "NarrowerTerm" (except subfield "y" type as "Period", "z" as "Place" and "v" as "Format") and populate "relatedType" with v=form-subdivision, x=general-subdivision, y=chronological-subdivsion, z=geographic-subdivision.
