Special Princeton Conversion Processes
          Path:  APIS  :  APIS Documentation  :  Metadata  : Princeton Conversion  
  
  NB: This document is to be used in conjuction with the Princeton / APIS Conversion Data Map, which includes requirements for straightforward data conversions. More complex conversions (e.g., those involving multiple fields or data manipulation) are documented below.
  1. Dates (046)

    Convert MARC 046 dates as following:

                             046 |aq|b500|d690

    converts to:

                            cuDate_1 | 1 | -690
                            cuDate_2 | 1 | -500
    etc.
  2. Author/Associated Names

    Convert MARC 100 to cu100a and cu100r as follows:

    1. Move source 100 |a to cu100a as such
    2. Create a new cu100r with content "aut" [i.e., author]

      3. EXAMPLE

      100 |aEuripides

           converts to:

      cu100a | 1 Euripides
           and
      cu100r | 1 | aut


  3. Writing Material / Medium (cu655)

    NB: Spec/conversion error -- "ostraca" spelled "ostraka" in Princeton records; not correctly converted to cu655 (resource type) fields.

    1. Transfer source MARC 300 field to APIS record as such.

    2. Also scan source MARC 300 field content for specified writing material / medium and generate a single cu655 field according to the following conversion table. (NB: The $ indicates wild card truncation.)

      Material/medium conversions
      300a text
      		   cu655 genre term
      papy$
      		   Papyri
      ostrac$
      		   Ostraca
      lead tablet
      		   Lead tablets
      wooden tablet
      		   Wooden tablets
      parchment
      		   Parchment
      paper
      		   Paper
      linen
      		   Linen

      EXAMPLE:

      300 |a1|fitem :|bpapyrus, twenty-one partly joined fragments ...
      converts to:

      300 | 1 | 1 item : papyrus, twenty-one partly joined fragments ...
      and
      cu655 | 1| Papyri
                                                         
  4. Reference / Link to Duke Databank of Documentary Papyri (DDBDP)

    Convert incoming 510 fields with either P.Princ. or P.Oxy. references (only) to both cu510 and cu510_dd (DDBDP citation form for link to Project Perseus)

    EXAMPLE

    "|aP.Princ. II|b15"

         converts to

    cu510 | 1 | P.Princ. II 15
         and
    cu510_dd | 1 | P.Princ.:2:15
