Here’s an item that has been on my mind for awhile. Inside a title, a  
legal case name or the title of another work are often set off with  
different font attributes. I would like to handle these with a simple  
wiki-style markup, but I’m not sure whether that is within the scope  
of CSL. Basically, underscores, asterisks and quotes would be  
"flip-flops" that distinguish the enclosed text on the basis of  
italicization, boldface and single- or double-quotes respectively.  
So:

italic title: My Work Concerning _Other Work_  
becomes: _My Work Concerning Other  
Work_

roman title: My Work Concerning _Other Work_  
becomes: My Work Concerning _Other  
Work_

quoted title: My Work Concerning "Other Work"  
becomes: “My Work Concerning ‘Other Work’”

… and so forth.

I’m wondering whether this kind of sub-field mangling is something to  
be controlled by the CSL specification, or whether it can be done  
independently by the application. If the former, I wonder whether it  
might be possible to reach agreement to allow this kind of handling  
through a variant (of which the syntax described above would be one),  
since there is a demand for the functionality, but systems running CSL  
may have differing capabilities for representing sub-field decorations  
or structure.

There is a related issue concerning Bluebook case names (subsequent  
references use only one party name), but that’s a bit more  
complicated, so I’ll hold it for later unless there is interest or  
need.

Well, the problem is this also touches on data transportability  
issues. So standardization would be valuable.

There are two issues:

1. encoding syntax. Your wiki syntax is one option. But there are  
others (embedded XHTML, for example). If wiki, I’d opt for as simple  
as possible, so probably only support italics/underlines and quotes.

2. does CSL need to know about this? I really don’t know. It certainly  
does if we want to attach some kind of semantics to different kinds of  
inline markup: titles, species names, etc. If all we care about is  
presentation, then it might not matter.

My thoughts on this, which I hope make some sense:

Unless there are cases where presentation really depends on semantics (e.g.  
a (fictitious?) rule that a “flip-flop” should occur, except when the  
italicized text represent a species name), I think support for semantic  
markup shouldn’t hold up an implementation of support for inline markup.  
Some people are now doing crazy stuff to get their bibliographies right (  
[http://forums.zotero.org/discussion/3875/rich-text-in-titles/#Item\_11](http://forums.zotero.org/discussion/3875/rich-text-in-titles/#Item_11)) ;),  
and I really think support for inline markup should be part of the  
core-functionality of any bibliography tool (it’s the one reason I’m not yet  
advocating Zotero with my colleagues). Also, if the first assumption holds  
(that semantics aren’t required), I don’t see the point in adding anything  
to CSL, but I guess it would ease things down the road if CSL processors are  
able to digest standardized (e.g. wiki) inline markup. Finally, isn’t there  
the room to support multiple types of syntax (which would mean that there  
isn’t a need for a final decision on this)?

I agree this should be dealt with in some, and that we should do so  
for the 0.9 release. Have you added it to the tracker?

Just as a followup:

This is a difficult issue, and I know of no existing solution that I  
consider satisfactory.

The reason this is difficult is that it touches on a lot of disparate  
issues: data modeling and encoding, output formatting, etc. in a  
format that tries to be agnostic as possible about these details.

I see a couple/few options.

1. We say CSL implementations should understand a handful of stuff  
supported in, say, markdown: italics/emphasis, bold/strong, quotes,  
superscripts and subscripts. We say nothing else except that  
implementers should know what to do in different cases; if you have a  
book title like “Some \*Inner Title” and the tttle is italics, then the  
inner title flips to normal. This is what Frank mentioned.

The only useful thing about this approach is that it works for getting  
proper presentation, and it’s simple (no changes to the schema).

But for people like me who really value structured and semi-structured  
data, this is really bad, because I can’t see it leaving any room for  
attaching semantics to that micro-content (except for quotes). You  
simply have no way to glean from the output what an italicized string  
inside a roman title means.

1. a variant of the above is to have a handful of standardized  
concepts, and some standard rules that can be overridden with some CSL  
fragments (I don’t know what they might be though). I think this is  
more to my liking, but perhaps difficult to do well.

But: a) is support for semantic markup incompatible with support for e.g.  
wiki markup? Can’t you just support an additional set of tags? Supporting  
wiki tags has the benefit of the fact that some content providers already  
mark up their titles in presentations encoding (italics, sub/superscript).  
And b), in some cases (simple) semantic markup just isn’t going to cut it.  
When citing papers, one should generally copy the metadata of that paper as  
closely as possible, even if it goes against style conventions. E.g. if a  
cited paper mentions a gene in the title, but it isn’t italicized (as it  
should be), you could annotate it with semantic markup as a gene but then  
you would need a way to indicate that it shouldn’t be italicized like the  
gene names in other (correctly written) titles. Or you could decide not to  
add semantic markup to that particular gene, but that would go against the  
semantic spirit.

Yes. But it can get difficult if you have too many of them. And this  
is still just syntax. It might be better to say what we want to be  
able to represent semantically, what implications that can or may have  
for formatting, and then go from there.

Hmm. I agree with up to the end. How these things should be handled on  
output is a function of the output style; isn’t it?

A related example is this:

British journals have different title-casing rules than U.S. journals.  
If I cite an article from a U.K. journal in a U.S. journal, I really  
think the title should be presented using the U.S. rules.

And would yield incorrect output if my position above is correct.

I personally can live a perfectly happy life without semantic markup. But  
that’s probably not the answer you are looking for.

Well, in the case of gene and species names, there isn’t any variability  
between styles. The formatting is standardized by convention, so here I  
don’t see a benefit of semantic markup in obtaining correct presentation in  
the output.

Do you need inline markup for this?

Well, more practically, my point is that we can’t know what solution  
is workable (generally) without assessing both. Presentation-only  
might work for you, but am not sure (e.g. I really don’t know) if it  
works across fields.

So your hypothetical example is only hypothetical?

For sake of argument, what happens if you have a species name in a  
book title that is otherwise italicized?

No; was just addressing your distinction between source data encoding,  
and output styling.

If one had a species name that was not italicized, you could not set  
it to output the correct styling (say, italicized).

But do you know of any cases where semantic markup is really required? I

My gut tells me it should flip-flop (i.e. become non-italicized), but some  
examples I found proof me otherwise:  
e.g. for the following reference, found at  
[http://genome.cshlp.org/content/13/2/244.full](http://genome.cshlp.org/content/13/2/244.full), Saccharomyces is italicized  
along with the rest of the title: Strathern J.N., Jones E.W., Broach J.R.  
(1982) The molecular biology of the yeast Saccharomyces— Metabolism and gene  
expression. (Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY).  
The same goes for some papers in the Journal of Biological Chemistry and  
Nature I checked. I’m not entirely sure however whether this markup is the  
result of a deliberate choice, or of limitations in the software used to  
format these entries.

Maybe I was unable to make myself entirely clear in my example. In my mind  
the most important principle here is that when citing, one should always  
copy the cited titles verbatim, including errors or non-standard markup. As  
such, the markup that should be present in the cited titles (e.g. gene and  
species markup), is not a function of the output style of the manuscript but  
purely related to the cited sources.

So let’s itemize what we know.

Here’s the stuff I deal with personally in my corner of the social  
sciences/humanities:

1. titles within titles; in some cases they are placed in single  
quotes, in some cases double-quotes, and in other cases italicized (or  
flipped).

2. quotes within titles

3. foreign phrases; not sure off the top of my head how these are  
handled; I think it varies

I gather that you also deal with:

1. species names

2. chemicals?

What else is there?

Yes, I understand you, but just disagree. If an article lists my name  
as “B D’Arcus” but I have an output style that demands the full given  
name, there’s a problem.

Parties to lawsuits that are deemed “common litigants” in the view of  
the editor of the journal concerned? When citing the case in  
subsequent references, the case should be referred to by one party  
only, and the party that is not a common litigant should be used.

There is no generally accepted list of common litigants, and no  
generally agreed unambiguous standard for identifying one.

That might indeed be an exception to the rule (though full names are never  
used in my field).

Still fishing for a compromise between ease of entry and semantic  
markup, here’s another shot at the topic.

Having sub-field semantic markup would be useful, but it may not be  
necessary for the semantic details to be known to CSL. As Rintze’s  
data is set up, he knows for a given set of entries what the visual  
markup represents. At the application level (Zotero, say), that data  
could, for a given set of entries, be exported with the visual markup  
mapped to appropriate inline semantic tags. For CSL, though, if there  
are very few cases that cannot be covered by a wiki flip-flop scheme  
(that’s my impression from this thread), it’s not very painful to just  
leave the edge cases for manual touch-up.

If fully fledged semantic markup is left as a problem for another  
application to deal with, this would encourage people to adopt  
consistent, or at least congruent conventions for inline markup, and  
that would I think speed rather than hinder the emergence of data  
stores containing semantic hints. I think everybody wins.

A thought, anyway.

Resurrecting this ancient discussion to see if usage might have already become established. Since this occurred, citeproc-js and Zotero have adopted support for a limited set of HTML-like markup for inline formatting: [https://www.zotero.org/support/kb/rich\_text\_bibliography](https://www.zotero.org/support/kb/rich_text_bibliography)

I am wondering whether it would still be a good idea to formalize this feature in CSL. Either using the syntax adopted by Zotero and/or perhaps Markdown or CommonMark syntax (changing existing data to a simpler syntax would probably be doable for the clients that currently support such markup).

I’d be inclined to go with html (which obviously could be hidden by GUI tools like Zotero or Mendeley) because markdown syntax may not be unique enough (as in, you could see \* or \_ in regular titles).

The only reservation to putting this in the specs is that we currently don’t say much about the data model at all there. Not sure if that should matter.

My major thought is that we probably want consistent behavior across citeprocs, so listing the tags that must be supported seems like a good idea.

That’s not really a problem. CommonMark goes to great lengths to preserve many punctuation marks, especially mid\_word ones and those without matching marks like regular askerisk use.\* You would have to have a really weird title to get accidental formatting for any of the markdown features. I would much prefer Markdown as an implementor, and in fact I have an implementation going already. Since Markdown implementations often include smart quotes, this also saves a bunch of quote parsing. And it makes preserving backwards compat with citeproc-js’ micro-HTML (as I have come to call it) very easy: simply recognise those raw HTML tokens as they appear as open tag, then contents, then close tag in the standardised token stream. I will share my implementation shortly.

Of course, these considerations are minuscule compared to the difficulty of inputting raw HTML tokens into your reference library; improving that is even more of a win. I would add finally that it’s a lot less work to support user-friendly formatting in a reference manager with Markdown than by “hiding the tags” with some rich text editor that probably won’t give you the right strict HTML subset to work out of the box.

\*Like this.

The Markdown family doesn’t seem to have syntax for superscript, subscript, or small-caps. The first two are heavily used in titles to articles in chemistry and biology.

Obviously as Markdown is HTML-oriented, you can still write superscript/subscript with `<sup>` and `<sub>`. So this isn’t a loss. There are some proposed extensions to support some of these (e.g. [https://talk.commonmark.org/t/why-there-is-no-syntax-for-subscript-and-supscript/586](https://talk.commonmark.org/t/why-there-is-no-syntax-for-subscript-and-supscript/586)), but nothing we have to actually wait on. For small caps, you simply get a pair of tokens `HtmlTag("<span style=\"font-variant: small-caps;\">")` and `HtmlTag("</span>")`, with Markdown in between, that you can recognise instead of escaping it as `&lt;span&gt;` etc.

Would these titles benefit from [Pandoc-like math syntax](https://talk.commonmark.org/t/mathematics-extension/457) in $ signs? Biology I’m guessing no, but chemists might like a “pass this straight through to LaTeX please” where they get to `\usepackage{mhchem}` and not get bogged down in subscript soup. That’s not what math is, but same kind of thing at least.
