Dear Saa¹ha,
dear all,

the paper that I described in my earlier email (see below) has just been announced and published by NDMSO:

Proposal 2012-03: Data Provenance in the MARC 21 Bibliographic Format
( http://www.loc.gov/marc/marbi/2012/2012-03.html )

The full announcement is available here:

Best regards

Reinhold

>Dear Saa¹ha,
>dear all,
>
>I would like to inform you that there is a very similar approach to add
>information about classification data to the MARC format.
>
>Driven by the Dewey experts at OCLC and at the Library of Congress, and
>by the German National Library, there will be a paper on the MARBI
>agenda for June this year.  The goal is to add content designation to
>the MARC format for provenance information, or data about data.
>
>The draft paper as it is now has two sections, one about the immediate
>need of adding subfields to MARC 082, 083 and 084; and a second section
>about a broader approach that covers every MARC field, by defining a new
>field in the 88X range, and using $8 to link the two fiields together
>inside the MARC record.
>
>Data about data, or provenance information, may be split up into (at
>least) "Method of assignment" (basically in binary form, assigned by a
>machine, or not), and "Process of assignment" (by giving a URI, a
>process name, or some other description), and a "Confidence value",
>which is a numerical value.  These three parts may each form one newly
>defined subfield in 082, 083, and 084.  A subfield $q "Assigning agency"
>already exists in these fields.  The new field 88X may contain them as
>well, plus additional elements, as date and time information, and an
>identifier leading to an authority record.
>
>Regarding the timeline, we are still working on a complete draft, which
>then will have to be sent to the colleagues at NDMSO, and after some
>steps I expect the paper to be put onto the MARBI agenda and to be
>published some weeks from now.
>
>I have talked about this process during a meeting of the MODS/MADS
>Editorail Committee yesterday.  The Committee suggested to inform you
>and the whole community, and maybe wait what direction the discussion
>will take, and then see how this may work in MODS and MADS as well.

>Betreff: [MODS] machine generated classification in MODS
>
>Hello!
>
>Items are often classified according to different classification
>systems.
>According to the MODS schema, we can put several classification elements
>with different @authority attributes, like this:
>
>classification authority="lcc"
>
>classification authority="ddc"
>
>This is very useful! Good!
>
>Sometimes, each classification is achieved by a human. In other cases, a
>classication can be automatically generated by a software translating
>from a
>classification formerly done in another classification system. Such a
>machine generated classification is often less accurate and / or less
>granular than a classification done by a trained human.
>
>I wonder whether storing an automatically generated classification can
>be
>considered being within the scope of what MODS intends to accomplish and
>if
>it is the case whether we could add a new @generator attribute on the
>classification element. This would be an indication that the
>classification
>is automatically generated and it could also be used to store which
>software
>was used to achieve this translation. As a work-around, we could of
>course
>use the @edition attribute similarly to
>
>classification authority="lcc"
>
>classification authority="ddc" edition="22 machine generated from lcc by
>foo-software version 1.2"
>
>but I consider it would be more easily parsable (through XSLT etc.) to
>write
>
>classification authority="lcc"
>
>classification authority="ddc" edition="22" generator="lcc2ddc-foo-
>software
>v.1.2"
>
>or (maybe even better) through a URI
>
>classification authority="lcc"
>
>classification authority="ddc" edition="22"
>generator="http://www.lcc2ddc.org/version/1.2/"
>
>or similar.

>Regards!
