Any URL-type attribute, when viewed in the Displayed Attributes table or the Get Info pop-overs attributes tab will show a globe icon. When clicked, Tinderbox passes the value of that attribute to macOS Finder. Importantly, it is Finder [sic] that decides what app (or none) is used.
URLs, can be any Web-type URL (e.g. http://, https://, ftp://) or an application’s pseudo-protocol†. You can also use the
file:/// protocol for local files, but the File-type attribute is likely a better thing to use.
If clicking the globe icon does nothing, the problem may lie outside Tinderbox, noting that is it is Finder and not Tinderbox that decides what to do with the URL.
†. ‘pseudo-protocol’: Something that can be accessed in the manner of a protocol but is not in fact a protocol. A number of apps such as Bookends, DEVONthink, Tinderbox, MarginNote, to name a few that allow the user to link between data in such apps that are on the same Mac (or possibly the same local network—look at each app’s documentation for detail). Here, is an example of the pseudo-protocol for a single Bookends reference, as copied from my Mac:
bookends://sonnysoftware.com/61228. The example is to show the general syntax. The
bookends:// part is the pseudo-protocol and that which tell Finder what app to open and to which to pass the data.
App pseudo-protocol-documention. This is a very incomplete list of app and docs, but may help give a flavour:
bookends://. Bookends. PDF manual, p.74.
x-devonthink-item://. DEVONthink. App Help, article ‘Item Links’
tinderbox://. Tinderbox. aTbRef: Tinderbox URL schema.
omnioutliner://. OmniOutliner. App Help: The Edit Menu, at
Copy as Link.
- etc. There are other apps I don’t have, such as MarginNote, that have similar affordances. In making this list i’m reminded that , for better or worse, this inter-app ‘glue’ is generally not obvious to the non-techie user and ‘lightly’ documented. But most (all?) of these apps have user forums and/or tech support that are proactive, so don’t be reserved at asking for help/pointers to examples.
