Community Comments

  • First sample comment (by TonyLinde): ...
    • Response (by authorname): ...

  • At the Victoria interop I think we agreed that it would be a good idea to explicitly ban the use of "!" in identifiers, as that would have a special meaning in the VOSpace vos: scheme. The document as stands does not include this ban.
    • Accepted. The ban has been included as requested. (RayPlante - 22 Aug 2006)

-- PaulHarrison - 27 Jun 2006

Thre is still a little confusion in the revised document about whether "!" can appear in the resource key, although the ABNF list of reserved characters in version 3.1.1 now contains "!" the text that quotes them in the 2nd paragraph of 3.1.2 for the resource key does not - it would perhaps be better to remove the list in 3.1.2 and just make a link back to the ABNF.

-- PaulHarrison - 12 Oct 2006

    • thanks for pointing out this other location requiring the update; I will update accordingly. I will certainly add the link; however, the text needs to refer to it in a non-hypertext way so that it is clear when reading a printed copy.

Comments from the Technical Coordination Group

TWG members should add their comments under their name. The deadline for comments is 27 Oct 2006.

Mark Allen (Applications IG)

I approve.

Minor textual comments:

Introduction:

of the first type describe above...

-> of the first type described above...

3.1.1

Incomplete sentence in the Note:

...;this practice has the advantage of reducing the probability that two authority ID.

3.3.2 Typo in the Note: concatonated -> concatenated

Bob Hanisch (Standards & Documentation WG)

Speaking with minimal/no authority, given that S&D WG is inactive, I approve and, like the others, only suggest that the typos be corrected.

Jonathan MacDowell (sic) (Data Models WG)

I approve the rec. Please fix the 'concatenated' (latin: /catena/, chain) typo (and while you're at, please note for future RFC's that I'm Mc, not Mac :-)).

I did find it a bit confusing in places to figure out what rules were specific to this doc and what were merely echoing standard W3C URIs etc. - you might consider adding e.g "IVOA reserved characters" for "reserved characters". But it doesn't really affect implementers, so it's not a big deal.

I agree with Doug that it would be better to just accept case insensitivity. As I read the doc, I infer that Dataset IDs are not necessarily case insensitive following the stop character that terminates the resource identifier, since that part of the string is not (?) restricted by this document.

Reagan Moore (Data Curation & Preservation IG)

I approve the recommendation. There are a few minor typos that can be corrected: section 1.0 - replace "control of provides" with "control provides" section 3.1.2 - replace "has complete control their forms" with "has complete control of their forms" section 3.2.2 - replace "that a URI that refers" with "that a URI refers"

Francois Ochsenbein (VOTable WG)

please edit

Pedro Osuna (VOQL WG)

    Point 3.1.1 list of discouraged characters is missing the following ones to be in sync with the ABNF: "&" "$"
    As above in 3.1.2 for the characters: "!" "&" "$"
    The XML schema in the appendix refers (in the documentation section) to "version 0.1" while it should be 1.1

I approve the recommendation once this very minimal changes are introduced

Ray Plante (Resource Registry WG)

Submitting Chair: no comments.

Andrea Priete-Martinez (Semantics WG)

I approve.

Guy Rixon (Grid & Web Services WG)

please edit

Doug Tody (Data Access Layer WG)

I approve the recommendation with the following minor comments.

Section 3.1.1 recommends that applications present identifiers using all lower-case characters, while 3.1.2 notes that mixed-case may be used to improve readability. Since comparisons are already case-insensitive I suggest that we uniformly allow case to be used to improve readability and not discourage the practice.

Suggesting that the resource key is intended only for human consumption and is not semantically machine-interpretable is clearly not correct. Perhaps what is meant is that the content of the resource key has no meaning within the context of the IVOA as defined by this document (it may have meaning to a data provider or consumer).

3.2.2 Typo: "In addition to the syntax to the above syntax..." 3.2.2 Typo: "concatonated"

I am pleased to see the discussion in 3.2.2 of dataset identifiers. I was originally concerned (around page 5) that as the spec was written dataset identifiers were not legal IVOA identifiers, but eventually determined that the IVOA merely claims to recognize only the collection and that the full dataset identifier syntax is nonetheless legal.
