It is still in limited beta, but Google’s Universal Analytics continues to evolve. The more info I review, the more the tagging reminds me of Webtrends Source Data Collector tagging concepts. The new Javascript tag is called ‘analytics.js’ and it is documented at the Google Developers site, which includes links to the Universal Analytics Developer Preview Beta program as well. With the new tag is an extensive reference of methods, fields, limits/quotas and cookie specs.
