Thanks, @StephenL. I was aware of the URL field, but the limitation is that there is only one field for storing a link.
As your example shows, this field tends to be a useful place to keep a connection to the original source.
However, what to do if I now want to link this document (suppose it’s a Web Archive, or a pdf generated from a web site) to a couple other related documents (oh, say a spreadsheet, a RTF with some notes I’ve written, and a mindmap file)? This problem comes up as I try to draw links and relationships between documents.
Devonthink seems to be a great platform to accomplish this, but a quota of one outgoing link per document is constraining. I understand a million links could be embedded into documents, but that changes the document itself — not desirable, and in some cases, like a read-only file, not doable.
Extending the topic, suppose we had the ability to put in multiple links as metadata associate with a document. What then? How would one traverse and explore these links?
There is presently a link button that, when clicked on, takes you to the single url link associated with the document. But, in this hypothetical version of DevonThink, if you control-click on that icon a menu would pop-up next to the pointer giving you a list of target documents. As you hover over each choice, a small preview icon would show up next to the menu item. Select one, and you jump to it. Hit command-[ and you go back. Command-] go forward.
We can get even more powerful. The drop-down menu shows target links, a divider, and then source links (things that point to this document).
All this would be really amazing. One could build an amazing wiki of documents with this capability.
