Model consistency #7

Open dr-shorthair opened 3 years ago

dr-shorthair commented 3 years ago

Looking at the FSDF Feature Model illustrated in https://github.com/GeoscienceAustralia/FSDF/blob/master/fsdf_feature.md I have the following questions:

  1. What is the relation to the ontologies in https://github.com/surroundaustralia/fsdf-kg
  2. A number of the properties are similar to those defined in https://github.com/GeoscienceAustralia/FSDF/blob/master/rdf/common.ttl - is the intention to modify that, or just to copy them all into the fsdf: namespace? BTW - I like the hasXXX formulation
  3. The two accuracy properties have range xsd:float - should it be a scaled value (i.e. with a UoM) or is it some kind of ratio?

Hi Simon, thanks for your questions. My answer is as below and hope we discuss further.

  1. This FSDF feature model was developed as part of the ontologies in https://github.com/surroundaustralia/fsdf-kg, but it hasn't been fully covered and explained in that yet, as I checked today. It will be further updated. Your help is much appreciated.
  2. Yes, most properties were designed to be consistent as much as possible to https://github.com/GeoscienceAustralia/FSDF/blob/master/rdf/common.ttl. It was intended to use that as much as possible with some expansions. See https://github.com/surroundaustralia/fsdf-kg/blob/master/edg/ontologies/common.ttl.
  3. You are right, I think the accuracy properties should be updated to scaled values instead of xsd:float
