Not just because it dropped on my birthday, but I recommend skimming this post for a bit more nuance than what is provided by referring to a "semantic layer." And, which requires more exploration than can be provided in the post, or in my comment, the ontology service interacts in extraordinarily meaningful [sic] ways with is described in the post as "enterprise security architectures." A shorthand way to think about this is to consider how the ontology service can power ABAC (attribute based access control; see NIST 800-162). ABAC implementations offer security that goes beyond circular definitions "admin" or developer" to application domain particulars. Security for real time health systems, for instance, dive into specialization details, such as artifacts produced by, say, radiology intelligent agents. Setting security policies for such artifacts should never be placed in the hands of developers or security architect generalists. It would be interesting to get the author's take on how partial ontologies can be leveraged, since that is the reality for most point-in-time application uses for ontologies.
