Common Approach to Impact Measurement

Common Impact Data Standard

This site publishes the Common Impact Data Standard (CIDS) ontology, its companion modules, and SHACL validation files. Each release is available as machine-readable RDF, and most also have human-readable documentation.

Common Impact Data Standard (CIDS)

https://ontology.commonapproach.org/cids

A standardized way to represent a social purpose organization’s (SPO) impact model, such as its theory of change, logic model or outcome chain. It represents impact as defined by the Impact Management Project norms (now housed at Impact Frontiers) and lets organizations exchange impact information regardless of the impact models they use.

Accessing the ontologies

The ontology URIs /cids, /sff and /cfo use content negotiation: browsers get HTML documentation, and RDF tools get the current release in the format named in their Accept header. For an earlier release, use the file links in the tables above. Common Form is available as HTML, Turtle and OWL/XML only.
