"The Sequence Ontology is a set of terms and relationships used to describe the features and attributes of biological sequence. SO includes different kinds of features which can be located on the sequence. Biological features are those which are defined by their disposition to be involved in a biological process."

"The Sequence Ontologies are provided as a resource to the biological community. They have the following obvious uses:

  • To provide for a structured controlled vocabulary for the description of primary annotations of nucleic acid sequence, e.g. the annotations shared by a DAS server (BioDAS, Biosapiens DAS), or annotations encoded by GFF3.
  • To provide for a structured representation of these annotations within databases. Were genes within model organism databases to be annotated with these terms then it would be possible to query all these databases for, for example, all genes whose transcripts are edited, or trans-spliced, or are bound by a particular protein. One such genomic database is Chado.
  • To provide a structured controlled vocabulary for the description of mutations at both the sequence and more gross level in the context of genomic databases."

"The Sequence Ontology is part of OBO. It has close links to other ontology projects such as the RNAO consortium, and the Biosapiens polypeptide features."
