Hi Rupert et al, Thanks a lot for your valuable insights regarding use cases of digital identity with Stanbol and in semantic web in general. I think verified digital identity and semantic-web goes hand in hand, merging the concepts is beneficial for efficient and accurate disambiguation of entities and accurate semantic enhancements.
As you have suggested WebID can be used as a federated social profile across multiple SNSs, connecting to the same resources (contact info,photos, friends, interests) identified uniquely via WebID. The linked-data described by the WebID can be used to extract verified knowledge about the person. As Antonio has described WebID is a unique URI representing an entity and security is implemented using PKI. It can be used as an authentication mechanism across the web with WebID supported platforms. Essentially WebID is written in FOAF + some SSL which can be used to create a trusted graph of entities. For more use cases please refer [1], [2]. WebID is an emerging protocol and it's yet to be widely adopted. I too don't have prior experience with WebID integrations, but I'm very much interested to take a deep dive into the subject domain based on my research interests. There are several WebID providers such as OpenLink Data Spaces [4] and My-Profile [5]. If we go forward with integrating WebID in Stanbol as part of the federated social network integration or disambiguation tasks we can implement a WebID connector to such systems or implement a WebID provider on Stanbol side. WDYT? @Rupert: With regard to your opinion on using EntityHub as an index rather than the primary storage for the knowledge base, can you please elaborate more on why do you think so? Maybe Wiki-Link or Freebase [3] is a good option for such a knowledge base?
