Thread:Standard for abbreviated license: CC BY-SA or CC-BY-SA (1)

In the paragraph following the table the various licenses are written with CC unconnected by a dash: eg CC BY-SA. On "The CC licenses" page the licenses are written such that the CC is connected to the rest of the license with a dash: eg CC-BY-SA.

I'd always seen the abbreviations written with a dashes between CC and BY. Is there a de facto standard somewhere that we can use here?

Also, I noted that the licenses were listed in the table without the CC prefix. The CC can be inferred, except that PD doesn't have a CC prefix. But see Jane's comment below the table:

"PD is not a license - I think we should just nix PD from the chart as it may prove confusing, or define public domain and point this out. --Jane Park 20:06, 12 January 2011 (UTC)"

I think both problems are solved if we move PD out of the table and make it a separate paragraph.

Thoughts?
