The Comparative Data Analysis Ontology (CDAO) provides a framework for understanding data in the context of evolutionary-comparative analysis. This comparative approach is used commonly in bioinformatics and other areas of biology to draw inferences from a comparison of differently evolved versions of something, such as differently evolved versions of a protein. In this kind of analysis, the things-to-be-compared typically are classes called 'OTUs' (Operational Taxonomic Units). The OTUs can represent biological species, but also may be drawn from higher or lower in a biological hierarchy, anywhere from molecules to communities. The features to be compared among OTUs are rendered in an entity-attribute-value model sometimes referred to as the 'character-state data model'. For a given character, such as 'beak length', each OTU has a state, such as 'short' or 'long'. The differences between states are understood to emerge by a historical process of evolutionary transitions in state, represented by a model (or rules) of transitions along with a phylogenetic tree. CDAO provides the framework for representing OTUs, trees, transformations, and characters. The representation of characters and transformations may depend on imported ontologies for a specific type of character.

Pattern for Local Unique Identifiers

Local identifiers in Comparative Data Analysis Ontology should match this regular expression:
^\d{7}$

Example Local Unique Identifier

0000072   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Comparative Data Analysis Ontology should match this regular expression:
^cdao:\d{7}$

Example CURIE

cdao:0000072

Publications

2009 Initial implementation of a comparative data analysis ontology.

The metaregistry provides mappings between the Bioregistry and other registries. There are 8 mappings to external registries for cdao with 2 unique external prefixes.

Providers are various services that resolve CURIEs to URLs. The example CURIE cdao:0000072 is used to demonstrate the provides available for cdao. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
