TL;DR -- Valid for your image usecase only I would handle it that way:
Create a tiddler: Image-Licenses with the content: Everything that is tagged: $:/tags/Image is license: x, y, z ... <<list-links "[tag[$:/tags/Image]]">> and link the tiddler somewhere in the "Thanks to: " section of the wiki. -------------- Reasoning below: It's a management problem ---------------- On Monday, June 19, 2017 at 9:59:39 AM UTC+2, @TiddlyTweeter wrote: > > I have an issue.

SVGs use a text based XML <https://en.wikipedia.org/wiki/XML> (Extensible Markup Language) format. If you open it with a text editor or TW-editor, it looks very similar to HTML <https://en.wikipedia.org/wiki/HTML> (Hypertext Markup Language) and it is "human" and "machine" readable. see: http://tiddlywiki.com/#%24%3A%2Fcore%2Fimages%2Fdelete-button and open it. With TW we use a *manually stripped down* version of SVG. There is just enough "xml" left, that the browser or an other program can handle it. eg: (stripped down again for readability) <svg class="tc-image-delete-button tc-image-button" viewBox="0 0 128 128" width="22pt" height="22pt"> <g fill-rule="evenodd" transform="translate(12.000000, 0.000000)"> <rect x="0" y="11" width="105" height="16" rx="8"></rect> ... </g> </svg> If you save the delete button as an delete.svg file, open it with eg: inkscape, Edit the global Document: Settings: License to eg: CC-BY and save, you'll get something similar to this: <?xml version="1.0" encoding="UTF-8" standalone="no"?> <svg xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"; xmlns= "http://www.w3.org/2000/svg"; viewBox="0 0 128 128" height="22pt" width= "22pt" version="1.1" xmlns:cc="http://creativecommons.org/ns#"; xmlns:dc= "http://purl.org/dc/elements/1.1/"; class="tc-image-delete-button tc-image-button"> <metadata> <rdf:RDF> <cc:Work rdf:about=""> <cc:license rdf:resource="http://creativecommons.org/licenses/by/4.0/"/> </cc:Work> </rdf:RDF> </metadata> <g transform="translate(12)" fill-rule="evenodd"> <rect rx="8" height="16" width="105" y="11" x="0"/> ... </g> </svg> As you can see, now the (manually stripped down) <metadata> section is still "heavier" then the real content. ... That's why we completely stripped it in TW. ... BUT it contains a <cc:License> section, that is sufficient for your drag and drop usecase. Similar settings are available for every other image editor. eg: exif for jpg <https://en.wikipedia.org/wiki/Exif>, png, gif, and so on. So .... If the global program settings are done right, the license fields should be there already. So if you want to deal with it for images, you definitely should have a look at the editor-software. ... That's one reason, why I wrote: "*It's a management problem*" have fun! mario -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
