> The files in question are RDF which do qualify as computer language files
Yes, I would have thought so, given the principal intended use of any common (.n3, .ttl, etc) serialization. So, thanks, Arthur. I think I understand (enough) about various serializations you might want to use, including support for any of these, as we have already agreed:
text/n3
text/turtle
application/n-triples
application/ld+json
application/rdf+xml
application/xml
The OASIS TC Process section on "Computer Language Definitions" is motivated by the concern that machine-readable files be made available AS (separate) plain text -- that is, separate from an Appendix or (Sub-)Section within a narrative prose document. Prior to the formulation of the TC Process rule (here: https://www.oasis-open.org/policies-guidelines/tc-process#quality-formalLangDefns ). OASIS TCs would sometimes present an XSD, DTD, or other machine-readable file ONLY in the prose document, from which users would need to screen-scrape or otherwise extract content to create a usable "file" (directly usable by a parser or other applications software). Arguably, that extraction process is error-prone, and may not preserve white space conventions, etc, etc, etc. Hence: the requirement that any such representations (serializations, formats, whatever), even if displayed verbatim as display text within the prose document, must be included as separate files in each release. The manifest document we publish with each release includes an MD5/SHA-1 digest value for each such separate machine-readable file (QA support).
We have already agreed to provide support for transparent content negotiation, as needed, in providing representations (e.g., based upon Accept headers in requests).
The OASIS requirement to publish "plain text" as separate files is agnostic about how the plain text "computer language definition" files (static storage objects) are created or generated. We do want them created AS files and placed (bitwise) on the file system in the official publication hierarchy.
Similarly, it's understood that you can indeed generate the HTML for a vocabulary as part of your processing (XSLT or whatever). That's great (and cool).
So I think nothing is in doubt here other that the details about construction of the URIs for the primary prose document (or for multiple independently titled prose documents in a Multi-Part Work Product), where the URIs for a prose specification cover page should conform to the Naming Directives. For that purpose, is essential that commitment is made to "Work Product" as the fundamental entity: it is key to construction of the URIs, which transparently reflect the directory hierarchy in the production/publication server.
To make that clearer, perhaps: the section "Required Document URIs" pertains to construction of URI references for a prose Document Cover Page; see:
http://docs.oasis-open.org/specGuidelines/ndr/namingDirectives.html#specURIs
For a simple Work Product, there would be only one main/principal titled prose document, and it must conform to the template provided by TC Administation, with al the required sections. Its cover page displays the required URIs (aka "document URI") which identify the Work Product as a whole. Any other HTML documents that are part of the Work Product need not conform to the same "document URI" pattern: the filenames may be release-agostic and version-agnostic, for example (incorporating no filename component for Version or Stage or Revision).
The rules for constructing (prose cover page) "document URIs" are a bit more verbose, but follow the same essential pattern as for a simple Work Product having one primary prose document; the URIs add components for "parts" if the Multi-Part Work Product has independently titled prose parts:
http://docs.oasis-open.org/specGuidelines/ndr/namingDirectives.html#URIs-MP
Please let me know if we can provide additional guidance here.

The files in question are RDF which do qualify as computer language files.
RDF is not itself a format. RDF can be represented in several formats,
e.g. RDF/XML, Turtle. That explains why we have both .rdf and .ttl files.
In practice, Turtle is the source that humans edit. We programmatically
generate RDF/XML since not all applications support Turtle. In addition,
we programmatically generate HTML. We do this to provide a human-readable
representation. Think of this as being like Javadoc.
The RDF resource itself has a URI that omits the file extension. It is
supposed to identify the conceptual resource. We use HTTP content
negotiation to serve up the format preferred by the requester. This is a
W3C Best Practice. See [1].

Subject: Re: [oslc-promcode] Re: Including files in specifications
for PROMCODE
Kaz/Arthur/Steve,
Time out. I see now upon morning's re-read of my message below that in
the final portion, I cited the expected naming patterns for a typical
OASIS Work Products "prose document", which incorporates what we call a
"document identifier". I overlooked an embedded message (Arthur's) which
suggested that one or more of the files in question be treated as computer
language definition files. The example URI reference I provided for an
HTML representation would match a typical OASIS Work Products "prose
document" -- and we don't usually consider an HTML document a "computer
language definition".
TC Process uses examples to describe "Computer Language Definitions" [1],
-- XML instances, schemas, and Java code, including fragments of such --
which must be published as "separate plain text files", referenced by URI
reference from the Work Product's narrative/prose specification document
a)
https://www.oasis-open.org/policies-guidelines/tc-process#quality-formalLangDefns
b) ... " machine-readable computer language definitions (e.g.,DTDs,
schemas, WSDLs, XML/JSON artifacts...) [Naming Directives]
A "machine-readable" (aka) "Computer Language Definition" file in plain
text is one intended primarily for machine processing, not in styled
rendering intended primarily for reading as narrative by a human.
But I can see the need for clarifying discussion about the constitution of
Work Products in the PROMCODE TC and in related OSLC TCs, and I recall
that Steve sketched an outline of the types of files and resources that
would make up a typical Work Product (obviously a Multi-Part Work
Product). Let's take a step back -- and initially off-list -- to get
clarification on some of these details.
Thanks,
- Robin
[1] TC Process: Computer Language Definitions
(7) Computer Language Definitions. All normative computer language
definitions that are part of the Work Product, such as XML instances,
schemas and Java(TM) code, including fragments of such, must be well
formed and valid.
(7a) For Standards Track Work Products:
All normative computer language definitions must be provided in separate
plain text files;
Each text file must be referenced from the Work Product; and
Where any definition in these separate files disagrees with the definition
found in the specification, the definition in the separate file prevails.
(7b) For Non-Standards Track Work Products:
All computer language definitions should be provided in separate plain
text files; and
Each text file should be referenced from the Work Product.

Kaz,
Your question in the context of this thread seems to relate to the notion
of "Version" with respect to the OASIS identifier schemes -- and not to
vocabulary "versions" under a (different) open-services.net versioning
scheme ... right? Assuming that you mean OASIS "Version", I'll try to
clarify how we use namespace name identifiers and versioning
* Version:
http://docs.oasis-open.org/specGuidelines/ndr/namingDirectives.html#Version
A "Version" is identified with a unique Work Product, used in all releases
for the specification lifecycle for that Work Product ( WD, CSD, CS, COS,
OS). Once the Work Product comes to CS or OS (OASIS Standard) level (or
is abandoned), that "Version" is complete.
While a Work Product is progressed through its lifecycle, namespace name
identifiers can also be revisioned (e.g., incremented using numeric
components in sequence), per the wishes of the TC
The Naming Directives document clarifies that for namespace URIs using the
docs.oasis-open.org domain ( pattern:
http://docs.oasis-open.org/[tc-shortname]/ns/xxxx ), the final "xxxx"
should ( should, not must) "incorporate a versioning subcomponent (e.g., a
string like 201011 representing a date or v1.1 representing a version
number)". In the case of the OSLC specs, where legacy namespace name URIs
and construction patterns are being used, the OASIS guidance about
"versioning subcomponent" is not directly applicable
If the TC wants to use a namespace name URI for a spec that applies to
more than one Version of the specification (e.g.,
http://open-services.net/ns/promcode# ) -- that should be OK as far as I
know. Whatever URI aliasing machinery is set up to deliver the correct
representation from the OASIS server when the "open-services.net" URI
reference is dereferenced -- should fetch/deliver whatever the TC elects.
In the case of traditional OASIS specs, namespace name URIs have often
been versioned (per Naming Directives "should") in support of a TC's goals
for implementation, conformance, etc. But if you don't want to (verbatim)
version your namespace names, I think that's up to you, per SemWeb
expectations
Irrespective of the above, the use of "Latest version:" URIs is scoped to
a particular OASIS "Version". That's orthogonal to the conventions your
TC may want to use in versioning or nor versioning a namespace name URI
How OASIS "Latest version:" URIs work in the case of "Versions": the KMIP
Profiles will illustrate the point: "Latest" is bound to one Version, and
does not cross Versions
http://docs.oasis-open.org/kmip/profiles/
http://docs.oasis-open.org/kmip/profiles/v1.0/
http://docs.oasis-open.org/kmip/profiles/v1.1/

I will change our shape document in WebSVN as once they are approved, then
we can simply copy from WebSVN to docs.oasis-open.org.

When we have v2.0, if we use [1] as stable @prefix for v1.0 shape document
it will means v1.0 shape documents uses v2.0 vocabulary document, because
[1] redirect to v2.0 vocabulary document.
I understand we will never change existing v1.0 content but only extend as
v2.0, still confusing.
This wouldn't happen for shape document because it seems not have stable
redirect URL between major versions as you said:

Is my understanding correct?

Hi Robin,
(2) above also has been discussed, right?
Is it a correct behavior that v1.0 shapes refer to v2.0 or newer
vocabulary?
