## Description

## Ontology Info

| Field | Value |
|-------|-------|
| Acronyme | PHAGE |
| Description | This ontology represents the seven steps of phylogenetic analyses. Each root concept step is composed from a set of resource annotations (to represent the data-flow) and programs (to represent the control flow). Object properties serve to represent relations to annotate data (e.g. has_RetrievedInDatabase, has_ModeledBy, etc.) and reorder the sequence of programs (e.g. has_InputOutput).This ontology has been collected in a semi-automated way from well-known databases such as NCBI, GeneOntology, UniProtKB and Felsenstein’s Web site through Web crawling and mapping techniques. |
