First, the markup for one entry from the table of contents page for the ACM TACO (Transactions on Architecture and Code Optimization) journal:

The markup for the 'full citation' page is similar, with a little more information about the authors.
Here's the markup from the 'ACM Ref' link, which apparently is how they suggest you format it:

Citeproc XHTML output
I'm the author of the citeproc project, which includes a micro-format of sorts (though I never thought of it as such) in its XHTML output mode. See here for an example. The difference compared to the bibtex-derived model is that is a) more generic and b) hierachical.
It would be possible, certainly, to do a flat model if for some reason there was a good technical reason not to go hierarchical (though is there?)
The burden of proof is on *going* hierarchical, rather than a simpler flat solution. Complexity must be justified, not simplicity.
... but then you need to think outside the BibTeX box in any case. Any model of this sort ought to be able to handle legal citations, magazine articles, patents, etc. etc.; not just a narrow range of BibTeX types.
Per the microformats process, microformats are designed to support existing practice on the Web, anything else should be omitted from at least the first version.
Styles
This does NOT define a format, but instead shows how the format should be displayed. This is something out of the direct scope of this project. CSS styles will handle the look-and-feel of the text, and the author can put it in any order they choose. These links are mentioned for two reasons, one is informative, the other is so we know at least meet the minimum properties that are used in the styles.
- MLA Style
- Chicago, MLA, and APA styles
- Blue Book for legal citations
- Columbia University Citation Style developed for modern internet citations
