This note is challenging because of the possible value "0" (Private) in ind. 1. Otherwise, straightforward in that we can only map the main content subfield $a to "note on item" (and mint an IRI for item asssociated with the manifestation).

My thought is, since the "private" designation applies only to the note, the note needs to become a "metadata work" so we can say something about it.
Would something like this work? Other possibilities? (this is a transformation note for $a mapping)

    This is clunky - currently there is no property for a metadata work that indicates access restriction, but there's no direct path to a "metadata manifestation".

Wonder if this is the only tag with such an indication in an indicator or elsewhere about restrictions on letting people access it.

Please review, suggest better ways if possible...
Note that rdam: p30145 "restriction on access to manifestation" only accepts an unstructured description.
Could we use rdaw: p10004 "Category of work" and devise a category for a Metadata Work that designated its intended consumption? or possibly some other Work property?

I'd rather there was a controlled value meaning "private" somewhere we could plug in but can't find one.

Please note that there is a proposal to be discussed by RSC later this month which will allow rdam:P30145 to accept a structured description/VES. The proposal is likely to be accepted, and be incorporated into RDA early in the new year.

However, rdam:P30145 is not the appropriate property to use. As the example shows, it is a manifestation property, but the 'private' restriction applies to the metadata work and all of its expressions and manifestations. I agree that rdaw:P10004 is better, and there is no need to mint the metadata manifestation. The values of 'category of metadata work' are, in this context, binary: private or public?

The status of private vs public is related to other statuses that an RDF graph (metadata work) might have, such as "deprecated". Note that the Open Metadata Registry has a vocabulary of statuses for VES concepts. The status of RDF graphs must be an issue for linked data communities ... but I can't immediately find an appropriate resolution.

Thank you Gordon. I'm glad you see 'Category of work" as the better option, and just use the term unstructured. If we come across a VES that has a concept that comes close (private, not for publication, etc.) we could see whether we wanted to use it later. I don't know if this is the same as a status. I'd consider "not published" to be a status, but statuses can change. This should be a value somewhere that a system could use to prevent something's status from ever becoming "published".

I wonder what is achieved by mapping $u separately, when RDA does not allow recording IRIs for rdai:P40026 "has custodial history of item". Seems to me that $a and $u can be joined using a boilerplate:

ex:Item1 rdaid:P40026 "[$a] (Additional information can be found at $u)"

$u is repeatable, so right now in the code I'm doing reification multiple times.

<< ex:Item1 rdaid:P40026 [$a] >> rdawd:P10004 "Private". // Reified statement 1
<< ex:Item1 rdaid:P40026 "http://fakeIRI2.edu/fake1" >> rdawd:P10004 "Private". // Reified statement 2
<< ex:Item1 rdaid:P40026 "http://fakeIRI2.edu/fake2" >> rdawd:P10004 "Private". // Reified statement 3

I'd really like to cut down on the number of reifications needed. $u here is just a text string anyway.

I think @pan-zhuo is right; nothing seems to be gained from separate statements for a $u if that is just going to be a string. Reification to say something is private seems reasonable to me, though.

My opinion is that it doesn't matter much either way. I would consider that we conceived of this as a practice run, a demonstration of how to perform reification in RDA/RDF. So I would choose the demonstration that serves better as a demonstration, which I would say is "reification multiple times." But really I don't think it matters too much; either way, we make a good demonstration.

I'm confused about the use of rdawd:P10004; specifically, I'm most confused that a Work property would be used. How could the metadata WORK be private? Isn't the metadata Manifestation private? (Sometimes ubiquitous WEMIfication seems like a tremendous burden.) Then, on a related issue, I'm wondering how "private" can be considered a category for a Work. I don't see the public/private categorization is pertinent to works, so if the value "private" remains related to the metadata Work, wouldn't it make more sense as a mere note?

How could the metadata WORK be private? Isn't the metadata Manifestation private?

This reminds me that the minimum description of a work must include a link to an expression or manifestation. Apparently, we are not interested in the metadata expression (unless we want to talk about the language used in the metadata description), then we will need to mint a metadata manifestation anyway, is that correct?

If so, what does that manifestation IRI look like? Suppose you have a metadata work IRI

http://fakeIRI2.edu/MetaWork1

Is the manifestation IRI

http://fakeIRI2.edu/MetaMan1

Or,

http://fakeIRI2.edu/MetaWork1.rdf
http://fakeIRI2.edu/MetaWork1.ttl
http://fakeIRI2.edu/MetaWork1.html

@gerontakos: We are talking specifically about a category of metadata work that is a single metadata statement.

We could say that there are two categorization schemes being applied:

  1. Categories of work: static work; diachronic work; aggregating work; collection work (these are all explicit in RDA, but RSC has rightly decided not to offer guidance or vocabularies for "category" elements (one for each Entity).
  2. Categories of metadata work: single statement; multiple statement; public; private; single entity; multiple entity (categories may be combined). A category of "private" would be defined something like "A metadata work that is intended for a closed information system".

@pan-zhuo: For metadata WEM IRIs, we can flip the process I suggested for MARC 21 WEMs:

There is no 'record control number' that can be used as a local part, so we use our own running number (e.g. 1).
Start with Work: exW/1
Add Expression: exW/1 rdamo:P10078 exE/1 .
Add minimal conformance condition for Works: exW/1 rdawd:P10002 stringify(exW/1) .
Add minimal conformance condition for Expressions: exE/1 rdaed:P20002 stringify(exE/1) .
Or: exE/1 rdaed:P20062 "rdf+xml" . // has form of notation

The manifestation of this metadata work is the file that the transform writes to, so we can't mint it ourselves. Note that the manifestation of a set of metadata works is an aggregate of expressions of the metadata works, so it embodies an aggregating work and expression. The aggregating work is the transform because it selects, etc. the metadata works to create, realize, and embody.
