Definition for MODS XML element: is a container element used to provide detailed coding for physical parts of a resource. It may be used as a top level element to designate physical parts or under for specifying the location of a part within a host/parent item.

Subelements: detail, extent, date, text

MODS RDF expresses part as an aggregator (http://www.loc.gov/standards/mods/modsrdf/primer.html#aggregator) "MODS XML elements and are structured elements - they have subelements. Therefore in RDF these are represented by properties (locationOfResource and part) whose ranges (classes Location and Part) are what we refer to as “aggregator classes”: their members - the objects of these properties - becomes the subject for triples corresponding to the subelements.'

Example: ModsResource12356 part #BlankNode15

BlankNode15 rdf:type #Part

BlankNode15 partOrder “4”

BlankNode15 partLevel "v.2, no. 3"

BlankNode15 partCaption “no.”

BlankNode15 partNumber “2”

Any reason to revise the treatment of part?

The LC MODS RDF representation of is more or less a straight XML to RDF conversion. I am still unclear on what we really intend to represent with MODS and I don’t think I have ever really understood it. I think we need some clear examples of what information we are trying to represent, before we can make an informed decision about how it should be represented in RDF. The examples in the guidelines don’t help me very much.

I see that when submitting a comment if you try to indicate an XML element including the angle brackets, it strips the whole word - both brackets and element name. So in my previous comment I tried to indicate the element part with angle brackets and it came out "The LC MODS RDF representation of is more...." when what I meant was 'The LC MODS RDF representation element part of is more..."

I've been searching high and low for an implementation example. We (at Columbia) have used it sometimes under relatedItem, not as a top level element. However, I found this presentation about the Blue Mountain Project. See slide 22 http://musiclib.princeton.edu/sites/default/files/IAML%20BMP%20slide%20presentation%20140715.pdf

Good job digging up that one…

On the page titled “MODS Coding Sample for the June 6, 1905 Issue of Le Mercure musical”

Can I interpret this example to mean that the resource described consists of these three “things”

· Volume 1. caption “re annee”

· Issue 3”. caption “No. 3”

· Volume 1. (no caption)

But that doesn’t make much sense, there are two volume 1s.

Found the MODS records from that project on GitHub: https://github.com/pulibrary/BlueMountain/tree/master/metadata/periodicals Might offer some better examples.

This sort of situation is the reason that part was added as a top level element. It came about in digitizing newspapers at LC and during the development of ALTO. There was a need to describe the resource as something separate, not as a constituent of a larger one (in which case you would use relatedItem with part to show its relationship to the whole). So the only way to describe it was as part of a larger one and it didn't have any distinctive title. The powerpoint illustrates the use of METS, ALTO and MODS together--and this was exactly the context in which part was added. I'm a little confused by those MODS records on GitHub-- I don't see part as an element in them. I'll see if I can dig up some LC examples using part at the top level.

Working Group call 11/7/2014: Continue with current LC MODS RDF approach. See notes at: https://github.com/blunalucero/MODS-RDF/wiki/MODS-RDF-working-group-call-11.7.14
