Adobe - Omniture at one point had a library of these plug-ins listed in the support section for download. Most have since been removed for the company's desire for consulting involvement. As Simon Rumble put it, "the company has an annoying habit of secrecy."2 Rumble provides an excellent method for further understanding the plug-ins through de-obfuscation. Web Analytics Land provides a small library of plug-ins, and video/multimedia tracking can be found in a separate article.
We understand Adobe - Omniture's stance for protecting their intellectual property but also feel that shared knowledge through collaboration leads to progress. The idea is not to break legal and ethical boundaries but to empower others to help improve measurement efforts. Please share if this article has provided the means for additional functionality.
