 ```In the case of:    (01) Does 1 meter = 1.00 meter    (02) My suggestion would quantify the answer assuming you had the following concepts included for each ontology class:    (03) 1. The concept ( in this case 'length") 2. The value domain ( in this case 1 and 1.00) 3. The precision ( in this case a misalignment of a whole number and a number with tenths and hundreths) 4. A qualifier ( in this case "meter")    (04) This seems sort of basic, no??    (05) Duane    (06) Sent from my iPhone    (07) On 2009-09-29, at 8:31 PM, "Joe Collins" wrote:    (08) > Pat, > >> Well, actually, it is.
