Re: [ontology-summit] Progressing a Units Ontology - Now

[Onno Paap <onno.paap@xxxxxxxxx>]

The ISO 15926 reference data ontology is available at the following SPARQL endpoint:

http://rdl.rdlfacade.org/data

This endpoint accepts SPARQL queries.
If you open that address with a web browser it gets redirected to a search screen, where you can query the ontology.

It is also possible to open a SPARQL query screen at this address:

http://rdl.rdlfacade.org/data?info=&search=&sparql=

In this screen, if you issue the following query it will show units of measurements (Entity data type 'Scale' in the ISO 15926-2 data model):
-----------------------------------------
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX dm: <http://dm.rdlfacade.org/data#>
SELECT ?s ?p ?o
WHERE 
  { ?s ?p ?o .
    ?s rdf:type dm:Scale .
  }
OFFSET 0
LIMIT 100

     Starting to collect ‘unit of measure’ ontologies.
     I have placed the NASA SWEET “sciUnits.owl” ontology in the OOR
     repository(http://oor-01.cim3.net/ontologies) as SWEETunits.  I also
     modified that file to change two of the relations from imported (from
     the NASA math ontology) to native to the units ontology itself; this
     change makes those relations visible in a Protégé instance window.
     This minimally modified SWEET ontology is listed as ‘SWEETunits
     Mod1’. They are classified in the “File by Category” list as “other”.
     Using this category reduces the number of ontologies presented in the
     list, making it easier to find SWEET units – but it’s easy enough to
     find when “All Categories” are displayed.

     Any other unit ontologies we should consider?
