Understanding Match Properties in Concept Mapping

The *Match properties are used to relate, or map, concepts from separate (and typically overlapping) vocabularies that belong to different schemes. If T1 and T2 are concepts within the same scheme then you might say (T2)———skos:broader———>(T1). This is saying that the concept of Average Temperature has a narrower meaning and relates to the broader, more-general, Temperature concept — and assumes that there is common agreement on those meanings; if you can’t find/reach that conclusion but still want to show they associate, fallback to (T2)<———skos:related———>(T1).
