Subject: [OASIS Issue Tracker] Commented: (OFFICE-3435) ODF 1.2 CD05 Part 26.11.13 Incredible HYPERLINK Function
[ http://tools.oasis-open.org/issues/browse/OFFICE-3435?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=23049#action_23049 ]
Dennis Hamilton commented on OFFICE-3435:
-----------------------------------------
@Rob,
Whether or not an implementation recognizes a text string cell value as having the form of an URI and presents the cell as a hyperlink with that label has nothing whatsoever to do with OpenFormula and there is nothing that OpenFormula provides as a side-effect. In fact, OpenFormula can and should be blissfully ignorant of how hosts style results and present them as the values of cells (if that is what is being computed).
The problem with HYPERLINK(IRI, value) is that the result of the HYPERLINK function, in this case, is value, and the target of the URI is something that the HOST has to be informed of as a side-effect. Since there can be multiple HYLERLINK function references in the same formula evaluation, and the ultimate value might not be the direct result of any of them, there is far more magic involved here. I don't think OpenFormula has that magic wand, but I do believe it can dutifully report those IRI values to whatever sorcerer has been built into the HOST-dependent-behavior binding (conceptually).
[Reminds me of an animated feature set to the music of "The Sorcerer's Apprentice."]

> Key: OFFICE-3435
> URL: http://tools.oasis-open.org/issues/browse/OFFICE-3435
> Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
> Issue Type: Bug
> Components: Needs Discussion, OpenFormula, Part 2 (Formulas)
> Affects Versions: ODF 1.2 CD 05
> Reporter: Dennis Hamilton
> Assignee: Dennis Hamilton
> Fix For: ODF 1.2 CD 06
>
>
> ODF 1.2 CD05 Part 2 has an inexplicable definition for the HYPERLINK function.
> The description asserts that there is an effect on a cell.
> The description assrts that there is an effect on a cell even if the function's occurrence is not needed in the evaluation of the formula.
> The description asserts that there is a coordinated effect in how an IRI is composed (or multiples delivered) from individual occurrences of the HYPERLINK function in the same expression.
> The description asserts unjustifiable requirements on the implementation of an evaluator.
> Finally, the examples of this function are used to refine the definition. Only the simplest examples can be inferred from the definition.
> It appears that incidental consequences of a specific implementation are being appealed to, without concern for what is essential and good enough for an OpenFormula case and no matter what odd behaviors that implementations might have for cases that defy well-definedness.
