Hi Arthur,
Thanks for providing information about the TC's goals and plans in the use of namespace name URIs, content negotiation, etc.
I have lead responsibility on OASIS Staff for advancing our Web architecture best practices and server support, and indeed, I have discussed most of these OSLC-related issues with Steve Speicher [1a]. Please feel free to send email off-list () if it's sausage-making, or to discuss the TC's plans on-list as a means of providing early notice, so that the proposed naming design or server function can be evaluated.
A couple initial comments:
1. With respect to your note below about the use of content negotiation ("The only novel requirement here is that we need to support HTTP
content negotiation"): content negotiation is a topic I discussed with the OpenDocument TC members in May 2014, indicating our agreement that we will support content negotiation for applicable (semantic web) resources, as needed. We're on board! I wrote:
"We agree that it's expected and necessary to support content negotiation on the OASIS Library server(s) for the Linked Data resources, so we have plans underway to make that happen..." [2a]
The memo in [1a] {msg00022.html} mentions "content negotiation" in our framework solution several times, though the initial plans for using HTTP 3** redirects in connection with the open-serivces.net namespace URIs have been altered (reverse proxy)...
2. With respect to the hypothetical ("suppose") examples below which predicate the existence of information resources (files) rooted "at" locations like "http://docs.oasis-open.org/oslc-promcode/ns/*" , viz.,
"the content at:
http://docs.oasis-open.org/oslc-promcode/ns/core.html
the content at:
http://docs.oasis-open.org/oslc-promcode/ns/core.rdf
the content at:
http://docs.oasis-open.org/oslc-promcode/ns/core.ttl "
I understand these to be typical hypothetical examples of content negotiation, similar to what we see now on open-services.net, and broadly for SemWeb/linked data [3a]. For planning purposes, and especially if you plan to declare a namespace like "http://docs.oasis-open.org/oslc-promcode/ns/foo#" (or "http://docs.oasis-open.org/oslc-promcode/ns/foo" OR "http://docs.oasis-open.org/oslc-promcode/ns/foo/" ): we reserve any such path containing /ns/ for constructing identifiers only, and we never store (tangible/file) "content at" a location suggested e.g., by "http://docs.oasis-open.org/oslc-promcode/ns/core.html". Please see the Naming Directives for an explanation [ http://docs.oasis-open.org/specGuidelines/ndr/namingDirectives.html#ns-pathElementReserved ]. It is OK to use the path with /ns/ to construct identifiers for non-information items (viz., identifiers/names for named properties, classes, functions, dialects, faults, actions, named message types, etc).
3. Thanks for the references to Jazz.net for help. If the .htaccess file you mention is portable (or likely re-usable in part), please send it to me.
Thanks, and best wishes,
- Robin Cover
PS It's encouraging to see the uptake of ReSpec for authoring in the OSLC Member Section (affiliated) TCs, based upon the customizations provided by Steve Speicher. I strongly support that effort, and thank all of you (authors, editors, reviewers) who are assisting in that development effort, despite some (likely) growing pains. Congratulations!

Chet,
Thanks for the description of the process. I am glad to see that this
process includes artifacts such as schemas, wsdl, etc.
In our TC, we need to publish an RDF vocabulary (and some other RDF
files), as will other OSLC TCs. The W3C has published Best Practices for
this [1]. The only novel requirement here is that we need to support HTTP
content negotiation. This means that we need to serve up different content
types for a given URI, based on an Accept header. We've implemented this
at OSLC and jazz.net which both use an Apache web server. We created a
.htaccess file to generate 303 redirects, which is Recipe 3 [2]. We'd
deploy the .htaccess file into our root directory:
http://docs.oasis-open.org/oslc-promcode/
Let me be concrete. Suppose we assign the following URI to our RDF
vocabulary:
http://docs.oasis-open.org/oslc-promcode/ns/core
When the Accept header contains text/html or application/xhtml+xml we
respond with the content at:
http://docs.oasis-open.org/oslc-promcode/ns/core.html
When the Accept header contains application/rdf+xml we respond with the
content at:
http://docs.oasis-open.org/oslc-promcode/ns/core.rdf
When the Accept header contains text/turtle we respond with the content
at:
http://docs.oasis-open.org/oslc-promcode/ns/core.ttl

Subject: Re: [oslc-promcode] Re: Including files in specifications
for PROMCODE
Hi Arthur,
Here is the process that TCs follow to publish their work.
Initially the TC prepares a working draft of the specification. This can
be a combination of draft documents, schemas, wsdl files, etc. The TC uses
its document repository on its web page, its wiki and its svn to store
these elements. TCs do not have write privileges to docs.oasis-open.org.
When the TC is ready to assemble the content into an initial working draft
of the specification, someone - usually the editor or the chair - requests
a starter document from TC Administration using the support request at
https://www.oasis-open.org/resources/tc-admin-requests/work-product-registration-template-request
. Among other things this request does is let us work out with you all any
details about the final urls and organization of the spec when it is
published. The TC uses this starter document to prepare the working draft
of the committee spec. We can provide templates in doc or odf format. For
TCs that want to publish from their own source in xml, latex, etc. we'll
work with you to use this template as a guide to publishing the final form
needed.
When the TC is ready to publish its first Committee Specification Draft
and, if it chooses, release it for its first public review, it passes a
motion to approve those steps in a meeting of the TC or by a ballot. The
language you can use for the motion can be puled from the template at
https://www.oasis-open.org/committees/download.php/53768. After that
approval is made, someone submits a request to publish the CSD (
https://www.oasis-open.org/resources/tc-admin-requests/committee-specification-draft-creation-upload-request
) and, if desired, the request to start a public review (
https://www.oasis-open.org/resources/tc-admin-requests/committee-specification-draft-creation-upload-request
).
TC Administration will then takes your working draft as approved and
prepares the corresponding HTML and PDF versions and loads all the
components to docs.oasis-open.org. We'll notify the TC when its ready and
if a public review is to be started, announce that publicly as well.
There are further steps - handling comments from public review, approving
a Committee Specification by Special Majority Vote, etc. They are
explained here ->
https://www.oasis-open.org/resources/tcadmin/tc-process-how-to-guide-introduction
. This should get you started though.
Best regards,
/chet

Chet - As I understand it, our TC decides when to post documents at

Kaz & TC
I think our documents should use the permanent URLs. We can use SVN to
work on documents. I think we should post stable versions of documents at
docs.oasis-open.org/oslc-promcode/... and always include status
information in them to indicate if they are drafts, final, etc.

Hi Chet,
Thank you for information. Now I understand.
Arthur,
Do you think we have to make current draft consistent to current URL( I
mean at SVN address) ?

Hi Kaz,
docs.oasis-open.org/oslc-promcode/... is where your approved TC work
products will be loaded and managed once the TC begins approving Committee
Specification Drafts, public reviews and the like. The working drafts you
produce prior to that step belong in your document repository or in the
SVN.
Best,

Arthur,
OK, I did it.
I agree with you. Cleaner URLs are needed. Thank you in advance for stable
URL information.
I use the repository is not for publishing but for version control among
our
TC members. Using wiki cannot manage versions with multiple wiki pages. So
basically, I will also publish at wiki at some milestones of drafts. We
can
choose using document repository(doc.oasis-open.org) or wiki for publish,
or
whatever OASIS recommends.

Chet - Thx.
Kaz - Please also upload the generated Turtle files to SVN. I only see the
generated HTML. This gives us stable URLs, e.g.
for HTML:
https://tools.oasis-open.org/version-control/browse/wsvn/oslc-promcode/shape
/trunk/Project.html
for Turtle:
https://tools.oasis-open.org/version-control/browse/wsvn/oslc-promcode/shape
/trunk/Project.ttl
However, we should really define cleaner URLs and set up HTTP redirects
from
those to the SVN URLs. The redirects should also handle content
negotiation.
We did this on the OSLC website for RDF vocabulary documents.
Steve pointed out that OASIS did have a mechanism for assigning cleaner
URLs. I will follow up on that.

HI Arthur,
We don't permit attachments on our wiki as doing so would likely have
system
and cost impacts that we can't afford.
For stable URLs, I suggest that you use the PROMCODE SVN system at
https://tools.oasis-open.org/version-control/browse/wsvn/oslc-promcode/?sc=0
. That is what other TCs use for the same purpose.
Best,

Chet,
We are producing some files as part of the spec. We want to assign stable
URLs to these files. I normally do this at OSLC using wiki attachments.
That capability seems to turned off at PROMCODE.
What is the best practice at OASIS (e.g. for XML schemas, WSDL)?
Can we get file attachments enabled in our wiki? Thank.
