User Labor proposes an open data structure, User Labor Markup Language (ULML), to outline the metrics of user participation in social web services. Its aim is to construct criteria and context for determining the value of user labor, which is a monetized asset for the service provider but not for the users themselves. We believe that universal, transparent, and self-controlled user labor metrics will ultimately lead to more sustainable social web.
A ULML record has three main elements:
Actions: A user’s actions (photos, videos, tags, comments…)
Reactions: People’s reactions to a user’s actions (likes, comments, votes…)
Network: Efficiency of the interconnections within a user’s social network
