New Features

Ontology Views

Views in BioPortal are subsets or other derivatives of ontologies in the repository that you can share with the community. You can upload views for any ontology, and review them, add notes, create mappings, and use REST Web services to access them programmatically.
A view can also serve as a mechanism to define value sets, which are quite useful in combination with the BioPortal ontology-term selection widget.
View generation and storage in BioPortal is the result of collaboration with Dr. Jim Brinkley’s group at the University of Washington.

NCBO Resource Index

We have initiated automated indexing of the contents of public databases using ontology terms. The indexing is done using the same workflow that drives the previously released Annotator web service.
Currently we index the following public databases:  Array Express, Biositemaps, caNanoLab, Conserved Domain Database,, DrugBank, Gene Expression Omnibus, Online Mendelian Inheritance in Man, PharmGKB, Reactome, ResearchCrossroads (Grant funding database), Stanford Microarray Database, UniProt KB, and WikiPathways.  The resulting annotations are accessible for browsing via the Resources tab corresponding to any ontology concept. The annotations can also be accessed programmatically:

Search filter for Ontology Groups and Categories

You can now limit your search to ontologies from a certain group (e.g., OBO Foundry, caBIG) or ontologies in a certain category (e.g., anatomy).
