These terms refer to two specific modes of data processing (a.k.a. reasoning), e.g., in validation and querying. Open-world reasoning is when you assume there could be additional data “out there” that you just don’t know about yet, so “missing ain’t broken”. Closed-world reasoning is when you assume that your dataset is complete, so “missing” is a validation error. Yes, there is "open world assumption" and "closed world assumption" that are modes of data processing. Note I carefully did not use those terms. There is also "LOD" which talks about open data, but makes no statement about mode of processing. So what shall we call the difference between the open web and my private, internal data store? Is it open vs. enterprise? But the fact is that I expect my data to ALSO be available in a web-based environment that 1) uses the open world assumption and 2) is where anyone can say anything about anything. kc -- Karen Coyle kcoyle@kcoyle.net http://kcoyle.net m: 1-510-435-8234 skype: kcoylenet/+1-510-984-3600
