There have been a few recent threads on the LOD and Semantic Web mailing lists that boil down to the fundamental issues of profitability, business models, and Linked Data. Situation Analysis ================== Business Model Issue -------------------- The problem with "Data"-oriented business models is that you ultimately have to deal with the issue of wholesale data copying without attribution. That's the key issue; everything else is a futile dance around this concern. Profitability Issue ------------------- Profit is the consequence of a functional business model. Ultimately, an entity, whether a person or an organization, has to orchestrate the intersection of pain, value opportunity, capital, value creation, market demographics, packaging, and value distribution. Linked Data ----------- As demonstrated by the Web -- on a daily basis -- our modern economy is driven by Linked Data in digital form. Nothing has really changed beyond the fact that value and its distribution network are increasingly digital. Problem Resolution ================== Relations & Relationship Granularity ------------------------------------ Linked Data has always been the engine of the Web economy because every link on the Web denotes (i.e., names or "refers to") a Relation. We know everything is Related, but we don't always know the specifics of a given relationship. What's changing today is the fidelity (or granularity) of these Relations. Thus, rather than having a Web-based economy comprised of coarse-grained relationships between entities of a specific type, the Web is evolving to incorporate new entity types in conjunction with new relationship types. Basically, the Web is becoming more fine-grained. Note -- • a Relation is a set of Relationships • Relationships may be represented in different ways, e.g., Table Records (typically presented as grids or spreadsheets), or Entity Relationship Statements (often presented as graph pictorials, like network or entity relationship model diagrams). Relation and Relationship Semantics ----------------------------------- The semantics of Relations, combined with Linked Data, are the key to addressing the challenge of "data copying without attribution". Their contribution is to add the following to the mix: • verifiable identity • access controls • trust Today, it is possible to produce and publish Linked Data (privately or publicly) while also constraining access via the use of data access policies. These policies may also be in Linked Data form, and they determine what privileges are granted to specific organizations, people, or machines. Technology ---------- The technologies that make this possible, right now, are as follows: • Linked Data HTTP URIs • SPARQL endpoints • entity relationship semantics based on the RDF model • Authentication protocols such as WebID+TLS, OAuth, OpenID, and others still taking shape (Web Keys, for example, which extends basic HTTP Digest Authentication) Conclusion ========== The Web is already driving our economy. It's how Google, Facebook, Yahoo!, and the like pay their bills. All that's happening now, in this industry inflection, is a move to a more distributed framework where participation in the Web-based economy doesn't require airport-sized data centers. You shouldn't have to be burdened by the challenge of providing services to the the whole world in exchange for $0.00 or nothing at all -- that's a game for behemoths like Google, Facebook, Twitter, etc. Linked Data (what the Web has always been about!) is an economic engine for value producers of all shapes, sizes, and forms.
