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 Modelscale: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
