Re: SKOS Shuttle 2.2.6 available as RDF Composer

Dear Neil, Martynas,  dear communities

(I do not find quads are the best idea to type an RDF value - although there were already some publicly financed projects proposing it).

Upon Neil’s kind remark and explanation, Semweb decided to finance the implementation of units of measure in SKOS Shuttle:

SKOS Shuttle allows by now the definition of RDF typed custom attributes choosing a type from 58 available units of measure which are (temporarily) defined in https://semweb.ch/lod/2016/12/unitsofmeasure.rdf <https://semweb.ch/lod/2016/12/unitsofmeasure.rdf> (small changes might be published here in the next days) and loaded in SKOS Shuttle, waiting for W3C to come up with.

The defined units of measure are the ones described in https://en.wikipedia.org/wiki/International_System_of_Units <https://en.wikipedia.org/wiki/International_System_of_Units> and https://en.wikipedia.org/wiki/Imperial_units <https://en.wikipedia.org/wiki/Imperial_units>. they are mapped to types in https://www.w3.org/TR/xmlschema11-2/ <https://www.w3.org/TR/xmlschema11-2/> - please advice if some important units are still missing. Following Neil’s humorous hint and only upon regular commercial request further units e.g. from  https://en.wikipedia.org/wiki/List_of_humorous_units_of_measurement <https://en.wikipedia.org/wiki/List_of_humorous_units_of_measurement> will be added. 

RDF custom attribute are typed in SKOS Shuttle using the same combobox as for choosing a W3C type, like shown in https://skosshuttle.ch/gen/images/sksunits.png <https://skosshuttle.ch/gen/images/sksunits.png> (also subject to small changes in the next days).

Thus the modelled example https://skosshuttle.ch/gen/images/skspiston.png <https://skosshuttle.ch/gen/images/skspiston.png> shows now a “diameter" and a “height" in inches. 
The type “Inch” is defined as swunits:inch i.e. http://semweb.ch/lod/2016/12/unitsofmeasure.rdf#inch <http://semweb.ch/lod/2016/12/unitsofmeasure.rdf#inch>, and relies upon the W3C type https://www.w3.org/TR/xmlschema11-2/#double <https://www.w3.org/TR/xmlschema11-2/#double>).

Ergo by now SKOS Shuttle allows you by now to start using RDF typed data and hence to model not only engineering but physics domains.

Thank you, Neil :)

From the representational point of view, this need would be solved by simply define the unit of measure into the value type expression like (hypothetically)

This is a recurring problem with RDF triple modeling – there are not enough places in a triple to put all the information you need to qualify a dimension. A valve hasproperty height AND inunits centimeters. A quad already.

>> In the current release You have to name the attribute to have the measure directly in its name, for instance instead of “Diameter” you take “DiameterInches”.

>>  
>> I am proud to announce here that SKOS Shuttle has reached per today a further degree of maturity. 
>> With Release 2.2.6 SKOS Shuttle permits to create SKOS networks enhanced as follows:
>>  
>> 1) Integrating OWL classes at concept level (inherit all OWL class data properties)
>> 2) Allowing creation of Custom attributes at concept level according to values in https://www.w3.org/TR/xmlschema11-2/ <https://www.w3.org/TR/xmlschema11-2/> 
>> 3) Allowing (symmetrical) Custom Relations to link concepts (finally allowing special constructs like "part-of”)
>> 4) Inserting SPARQL-UPDATE stuff (minor feature) in SPARQL tab
>> 5) Editing coloured RDF statements in the appropriate tab.
>>  
>> De facto SKOS Shuttle has become per 2016 an RDF composer.
>> See a (really) tiny example in https://skosshuttle.ch/gen/images/skspiston.png <https://skosshuttle.ch/gen/images/skspiston.png>
>>  
>> SKOS Shuttle is free to use (inside a fixed resource extent), educational institutes gets the “silver”Tarif for free.
