Goals of the meeting Motivation and market for this work (22IT) Rules for conducting the meeting (22H1) Call for agenda items, adoption of agenda (22H2) Proposed work plan going forward

Motivation and market Ontology Summit 2009 explored the use of ontologies in standardisation Candidate projects identified Single ontology for units of measure identified as suitable for immediate action Measurement units and dimensions (or dimensionality) essential for the meaningful communication of –measurements –design specifications –scientific data –medical data –environmental data and regulations –commercial transactions Ontology of measurement units and dimensions would have wide utility in many IT standards

Benefits of work The proposed ontology will be Be applicable to any developer of information models or applications that require an unambiguous definition of units in a digital form that can be utilised by a wide range of applications Improve the quality of standards Support more robust implementations Support semantic integration Support conformance testing Highlight logical inconsistencies and ambiguities that need to be addressed

Objective Development of the draft of an international standard ontology for "Units of Measure and Quantities –single or federated integrated ontology –represents fundamental and derived units of measure and their relationships –independent of industry sector and applications –based on available specifications and standards –publicly available, free of charge

Scope of ontology Base dimensions and units of the SI (metric) system Metric scale factors (nano-, micro-, milli-, kilo-,...) Rules for constructing various derived units Designations of the most common derived units such as joules, watts,... Non-metric base units, e.g., inch, foot, pound More popular derived units, e.g, quart, cup Needs to include external references Links to colloquial names and addresses May need to include rules for use Anomalies should be addressed Representation in common forms – OWL, CLIF

Targets for today Report work to date Confirm scope of activity Confirm technical approach and features Agree deliverables Develop work plan Identify potential resources Establish organisation

Some rules of engagement No-one seems to have a complete answer Focus is using ontology to add value to existing work Deliver benefit to end users We are not trying to: –Establish new research projects –Fund pet projects –Solve deep philosophical arguments Parking lot will be used!
