[DCRM-L] RBMS PS Review Q1: Core Elements

Wed Nov 29 14:42:47 MST 2017

Thank you, Deborah, for bringing up this important question of the relationship between core and required. While RDA does not explicitly state what it means to be required, there are only a few transcribed elements where RDA specifies what to record if the information is not present: title proper, and the elements of the publication, distribution, and manufacture statements. Therefore, the practice has emerged that core is "must include if present, but may omit element if not" (level 3), unless the element instructions specify otherwise.

For example:
Designation of edition: Core element in RDA.  No instructions on what to do if item lacks an edition statement. Practice to omit element if no edition statement on the piece (level 3).
Title proper: Core element in RDA.  2.3.2.10 specifies to either take the title from another source or devise one (level 1).
Place of publication and Publisher's name: Core elements in RDA.  2.8.2.6.5 and 2.8.4.7 specify to record "Place of publication not identified" or  "publisher not identified," respectively, if the information is unknown (level 2).
Date of publication: Core element in RDA.  2.8.6.6 specifies to supply or approximate the date of publication if not identified on the manifestation. (level 1).

I believe this assumption that unless element instructions specify otherwise, core is "must include if present, but may omit element if not" is the basis of the current core list is the draft RBMS PS.  Perhaps, this should be more explicitly spelled out.  Also, in looking back at how RDA proper and LC-PCC PS handle core elements, both do not include a full list of core elements at 0.6, but identify core elements by making a statement at the element level, along with any specific parameters (e.g., if more than one, only the first recorded is required).  Would that be a helpful approach for us to take? Or both?

In searching RDA for the meaning of "core," I don't find it pinned down. Glossary=An indication that an RDA element, element sub-type, or sub-element is required to support specified user tasks according to the FRBR assessment of the value of each attribute and relationship. What's missing is an explication of what it means for an element to be required. Must it contain substantive value, or is it simply enough to include the element but indicate that the information is not available? We've been assuming the latter I think, but does RDA spell it out anywhere?

For example, DCRM requires place of publication and date of publication, but while "[S.l.]" is allowed for the place, "[s.d.]" is NOT allowed for the date; some kind of conjecture must be made, however vague. I'd like to maintain the distinction. Would that be managed through a conformance statement?

How about when only the first instance of a transcribed element is core? Can the core instructions require the mark of omission?

How about elements like the ISSN, which will not be present on early printed materials. If we designate it as core, does that mean we have to always include the element and indicate that there is no ISSN?

I think we need to have an explicit understanding of what it means for an element to be designated core before we can settle on a core list. My queries here include 3 possible levels of core: 1) must contain a substantive value; 2) must indicate that the information is not available; 3) must include if present, but may omit element if not.

Subject: [DCRM-L] RBMS PS Review Q1: Core Elements

The first question for RBMS PS review is which RDA elements should be identified as core for rare materials? The list in RDA proper is relatively short and there are rumblings that in the future there will be no list of core elements in RDA proper and specialist communities will be responsible for establishing their own lists.

Questions for discussion (please respond to the list):

*         Should all transcribed elements be core?

*         Is the proposed RBMS PS list of core elements (see list below) appropriate? Are they are elements that should be added or deleted?

*         Should any item attribute or relationship be core?

The current draft of the RBMS PS proposes the following list of core manifestation elements:

Title

*         Title proper

*         Parallel title proper

*         Other title information

*         Parallel other title information

*         Variant title

*         Earlier title proper (for serials)

*         Later title proper (for serials)
Statement of Responsibility

*         Statement of responsibility relating to title proper (if more than one, only the first recorded is required)

*         Parallel statement of responsibility relating to title proper?
Edition statement

*         Designation of edition

*         Parallel designation of edition[DJL]  May omit after 1st with mark of omission

*         Statement of responsibility relating to edition

*         Parallel statement of responsibility relating to edition[DJL]  only required if parallel edition statements subsequent to first have been transcribed

*         Designation of a named revision of an edition

*         Parallel designation of named revision of edition[DJL]  May omit after 1st with mark of omission

*         Statement of responsibility relating to named revision of edition

*         Parallel statement of responsibility relating to named revision of edition[DJL]  only required if parallel designation has been transcribed

Numbering of serials[DJL]  Defer to members of DCRM(S) team

*         Numeric and/or alphabetic designation of first issue or part of sequence (for first or only sequence)

*         Chronological designation of first issue or part of sequence (for first or only sequence)

*         Numeric and/or alphabetic designation of last issue or part of sequence (for last or only sequence)

*         Chronological designation of last issue or part of sequence (for last or only sequence)

*         Alternate numeric and/or alphabetic designation of first issue or part of sequence

*         Alternate chronological designation of first issue or part of sequence

*         Alternate numeric and/or alphabetic designation of last issue or part of sequence

*         Alternate chronological designation of last issue or part of sequence
 Production statement

*         Place of production[DJL]  This can't always be ascertained. If designated as core, would a "place or production not identified" satisfy the requirement?

*         Date of production (for a resource in an unpublished form)[DJL]  ditto
Publication statement

*         Place of publication (if more than one, only the first recorded is required)

*         Parallel place of publication[DJL]  (if more than one, only the first recorded is required)

*         Publisher's name (if more than one, only the first [DJL] three recorded is required)[DJL]  with requirement to summarize the omitted names

*         Parallel publisher's name[DJL]  (if more than one, only the first recorded is required)

*         Date of publication
Distribution statement (if present on the resource)

*         Place of publication distribution

*         Parallel place of distribution

*         Distributor's name

*         Parallel distributor's name

*         Date of distribution[DJL] Only if it appears as a separate distribution date when there is also a publication date
Manufacture statement (if present on the resource)

*         Place of manufacture

*         Parallel place of manufacture

*         Manufacturer's name

*         Parallel manufacturer's name

 Series statement

*         Title proper of series

*         Parallel title proper of series

*         Other title information of series

*         Parallel other title information of series

*         Statement of responsibility relating to series

*         Parallel statement of responsibility relating to series

*         ISSN of series[DJL]  see query above

*         Numbering within series

*         Title proper of subseries

*         Statement of responsibility relating to subseries

*         Parallel statement of responsibility relating to subseries

*         ISSN of subseries

And the following addendums to the RDA list of core elements for works and expressions:[DJL]  What is the rare materials reason for expanding the RDA core list for works and expressions?

Coverage of content (recommended)
Longitude and latitude
Dissertation or thesis information
Language of content
Script
Form of musical notation
Format of notated music
Medium of performance of musical content
Scale (for cartographic content)
Horizontal scale of cartographic content

Projection of cartographic content
Other details of cartographic content

Attached is the RBMS PS for the chapter 0 for additional context and background to the RBMS PS.  The RBMS PS were written to be read in tandem with the RDA proper instruction they correspond to, and consequentially some individual PSs may not make sense without referring to the original RDA instruction.
