Intro to the June DC VoCamp A few words from the Organizers: Ed Summer, Todd Pehle and Gary Berg-Cross

What are VoCamps VoCamp -informal events (unconference) –oriented to hands-on technical work and practical outputs –dedicated time creating lightweight vocabularies/ontologies –good enough models for people to start using Approach –"paper first, laptops second" format, where the modeling is done initially on paper and only later committed to code. However we have the help of Revelytix and their Knoodl tool –presentations and demos are short, highly on-topic to the vocabulary development process, and limited in number.

GeoVoCampSouthampton2011 GeoSPARQL feature/geometry & spatial relationships model, Scaled Vocabulary Feature types/points of interest, Events/time/Change Over Time Auxiliary Vocabularies

Scale Vocab Example Interest: There appears to be a need for a vocabulary that allows a spec. for the publication and consumption of a discretised view of data. Definition: A Scale is comprised of a number of defined Points arranged in a specific order. Example Scales for “Things” range across –None –One –A few –Some –Lots –Oodles

Portion of Scale Model scale:Scale a rdfs:Class; rdfs:subClassOf scovo:Dataset ; rdfs:label "Scale" ; comment "A Scale comprises of a number of defined Points arranged in a specific order."

Examples of Vocabulary Development 1. scale:hasPoint (members); 2. rdfs:subPropertyOf scovo:datasetOf ; 3. rdfs:label "has point" ; 4. rdfs:comment "Associates a Scale with the Point(s) of which it is comprised." 5. rdfs:domain scale:Scale ; 6. rdfs:range scale:Point.

Nearness Model- uses Scale Model Scale of nearest, near and close
