Subject: Re: [oslc-core] OSLC Query 3.0 public review responses

My point was that an HTTP status code has a semantic meaning and TAB just followed it. 301 means "this redirect will NEVER change". So, I plan to change the code returned by open-services.net. It's up to IBM to decide whether to follow the HTTP spec on ibm.com.

My point is that neither the specification documents nor the link checking tool can control the http status code returned by a server - so a blanket recommendation to always change the source to refer to the redirect target is not good practice - one must be more selective.

Thanks Nick,

I just looked into the comment TAB-1647 and, strictly speaking, they are fully correct regarding the substitution of the 301 permanent redirect code because you are not able to change permanent redirects (I mean you can but browsers can simply cache the 301 redirect FOREVER).

What we need to do instead is to  ensure https://httpstatuses.com/301is not returned. I recall asking Koneksys to set it to the https://httpstatuses.com/303code for RDF; I guess we need to extend it to HTML too. If IBM's homepage does locale-based redirect, it should use 303 (or the more common 302 code) too but I will stay out of that one :)

We should not follow all the recommendations concerning redirected links. For example, links to open-services.net/nsMUST stay as is, and not be changed to the target of the redirection: the redirection takes into account the content type being requested, and is also subject to occasional change. Similarly, I do not believe a link to ibm.comshould be redirected to the English sub-page: I might guess in this case the redirection is locale-sensitive.

Jim, you might want to mention to the reviewer these issues with their recommendations that a link that is redirected should necessarily be replaced by the target of that redirection. Obviously there are some cases where that action is appropriate, such as the Wikipedia and OASIS document links, or changing http to https.

Hi Jim,

Re TAB-1656:
I think we should reference
https://www.w3.org/TR/rdf11-concepts/#section-XMLLiteral. Note this is a non-normative specification for the reasons stated in that W3 document.

Re TAB-1657:
I don't understand the submitter's description. The spec is describing elements of oslc.where and these are not XML. Maybe all that is needed is a reference to a W3C document for xsd:string and rdf:XMLLiteral.

With all the moving around and the fact that I have had little time for anything other than working on high severity issues for two Jazz applications nearing release, I have no idea where the current OSLC Query 3.0 spec is. My last known reference is
http://tools.oasis-open.org/version-control/browse/wsvn/oslc-core/trunk/specs/oslc-query.html#conformance. Hopefully things should start ease up over the next few weeks and I will time for OSLC.

Best regards,

Here's the comments from the TAB with my initial responses. Could you (especially David) provide any needed corrections to my responses.
