Different icons for DOI vs HTML links

[stefan-kolb]

From @lc9275 One request: would it be possible to have different icons for doi and html like before?
Maybe we can do this for the url/doi column inside the main table.

[stefan-kolb]

@matthiasgeiger Do you think there are possible icons for that?

[simonharrer]

or @matthiasgeiger could we combine an icon with a text, so that we use the default icon for a document and add the text as an overlay?

[matthiasgeiger]

https://materialdesignicons.com/icon/library or https://materialdesignicons.com/icon/book for DOI?

Edit: textual overlay would be more complex...

[stefan-kolb]

I like the library icon. Although I'm generally not convinced to introduce two icons. I mean both just open a website. What if there are two URLs anyway?

[simonharrer]

maybe combine two existing icons: http://stackoverflow.com/questions/5797113/java-combine-imageicons

Reasoning for two icons: DOI leads to a full text provided by the publisher, HTML may lead to a background page or the paper on the homepage of the author. IMHO this distinction is quite common. Furthermore, this is also a kind of quality check: Do most of my entries contain a DOI?

[simonharrer]

Good idea for the database statistics.

[stefan-kolb]

But we only show one icon even if both links are there?!

@koppor to extend your reasoning I'd point out that several types of document do not have DOI: patents, books, reports, theses etc. Further, some "exotic" or very old paper may not have DOI. So, I vote for two different icons.

Multiple types. Textual overlay would be great. Or the icon of the type belonging to the link which will be opened on click. Maybe with a little plus in the lower right corner to show that there are more links?

[simonharrer]

We could use the barcode icon from the https://materialdesignicons.com/

[stefan-kolb]

Yeah thats cool!

[simonharrer]

@matthiasgeiger is the icon already included in the current icon font we use?

[matthiasgeiger]

Yes. Codepoint should be F071.
