I have been calling this type of metadata 'second party metadata', while Scott Wilson is here using the term 'social metadata'. As he describes, "APML (Attention Profile Markup Language) is a means of sharing an individual attention profile [and] ULML (User Labor Markup Language) is a specification for tracking the metrics of user participation in social web services." He's quite right when he says "neither APML or ULML is going mainstream anytime soon" but here's how it ought to work (it won't, not without a lot of kicking and screaming first, because of commercialization and privacy issues): this metadata is made accessible for harvesting, and when it is harvested, is used to create resource profiles, which assist in the distribution of resources.
