SSTIM is an open OWL and SKOS vocabulary for sensory stimulation. It mints identifiers for stimulation techniques, stimuli and their parameters, delivery media and body placements, exposure and safety boundaries, session records, and the evidence assessments attached to a claim. It exists so that auditory, visual, tactile and cross-modal stimulation protocols can be described and exchanged in one vocabulary instead of per-study prose, and it is used by researchers, tool builders and the W3C Sensory Stimulation Vocabulary Community Group.

Pattern for Local Unique Identifiers

Local identifiers in Sensory Stimulation Ontology should match this regular expression:
^[A-Za-z][A-Za-z0-9]*$

Example Local Unique Identifier
SensoryStimulation   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Sensory Stimulation Ontology should match this regular expression:
^sstim:[A-Za-z][A-Za-z0-9]*$

Example CURIE
sstim:SensoryStimulation

Providers

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier SensoryStimulation is used to demonstrate the providers available for Sensory Stimulation Ontology. Some providers may use a different example, which is displayed in the table below. A guide for curating additional providers can be found here.
