REA, a semantic model for Internet supply chain collaboration
REA (Resource-Event-Agent) is a semantic model for internet based Supply Chain collaboration developed by Dr. William McCarthy of Michigan State University. In this presentation for the ACM Conference on Object-Oriented Programming, Systems, Languages, and Applications (OOPSLA 2000), Dr. McCarthy and Robert Haugen, Logistical Software LLC outline a web-based semantic model for collaboration.
Before I dived into this thing - I asked myself what do these good people mean by using the word semantic in a semantic model for internet based supply chain collaboration? You can look up the definition here
se.man.tic: Spelled Pronunciation[si-man-tik]
– adjective
of, pertaining to, or arising from the different meanings of words or other symbols
Eg: semantic change; semantic confusion.
So in other words, a semantic model is really a language meaning based model. So, what do the authors mean by using the term sematic model?
By "semantic model" we mean a computer software model of real-world supply chain activities. Another term for semantic model from the field of knowledge representation is "ontology": the set of classes, relationships, and functions in a universe of discourse.
