 The Agora [[knowledge graph]] can be defined as a **hypergraph** `A` with a set of `k` **nodes** `N`[^node] (entities an Agora knows about) integrated out of **subnodes** `SN_0 .. SN_k` containing **subedges** `SE_0 .. SE_k`, aggregating into **edges** `E_0 .. E_k` (semantic links between entities inferred out of known subnodes). Edges are annotated implicitly by link context and explicitly via the application of [[agora protocol]]), which is extensible. 
 
-Building on the above and [[free software]], we model and detail how to implement a distributed system that provisions social knowledge services. Then we analyze some of these services and other potential applications of this system. Finally, we shortly explore possible social implications and future work.
