Although everyone in the social software world seems to be in love with OAuth, the Yammer contingent is critical of other standards OpenSocial seeks to align itself with, such as Activity Strea.ms. Pisoni said Open Graph is "a lot simpler of a description than Activity Strea.ms" and that the trend in social software is to "keep simplifying because, at the end of the day, it's about adoption."
OpenSocial advocates also tend to speak favorably about CMIS, the Content Management Interoperability Services standard, and its potential for integrating enterprise document management systems with social software. A more formal integration between CMIS and OpenSocial is under discussion.
When I spoke with Box CEO Aaron Levie prior to his keynote at the Enterprise 2.0 conference, he dismissed CMIS as too oriented toward "legacy" technology rather than the spirit of open Web standards. This was part of a conversation in which Levie dissed OpenSocial using almost the same words that Pisoni did.
"If I had to bet, I wouldn't bet on OpenSocial," Levie said. Google and MySpace may have embraced it but since Facebook didn't, developers have had little reason to invest in OpenSocial, he said.
When I organized a Designing Social Applications panel discussion for the Enterprise 2.0 conference and show, I wound up with an OpenSocial-friendly crowd, including OpenSocial board member Jonathan LeBlanc and Jive Software's Ryan Rutan (one of the people saying nice things about CMIS).
LeBlanc told me he hears that dismissive talk about MySpace a lot. It's true the initial OpenSocial specification "had all these weird social features and profile things that didn't make sense in a larger context," he said, during our Enterprise 2.0 panel discussion. Essentially, that early spec made too many assumptions about how a social system would be constructed. To make OpenSocial relevant to a broader audience, its architects broke it down into smaller components, making it possible to adopt just the portions that are relevant to your applications. With OpenSocial 2.0, they have moved to map OpenSocial to a family of other relevant standards like OAuth and Activity Strea.ms. While OpenSocial may not be welcome at Facebook, MySpace and Google are far from its only fans, he said. It's widely used by social sites overseas, including the largest one in China, RenRen.
Still, OpenSocial aspires to be an enterprise standard, influenced by companies like IBM who have worked to make sure it meets enterprise requirements. That may be precisely the reason it's treated with suspicion by upstarts who see themselves as more a part of Web 2.0 than Enterprise 2.0.
