ontologies_api

ontologies_api provides a RESTful interface for accessing BioPortal (an open repository of biomedical ontologies). Supported services include downloads, search, access to terms and concepts, text annotation, and much more.

Prerequisites

• Ruby 2.x (most recent patch level)
• rbenv and ruby-build (optional)
  • If you need to switch Ruby versions for other projects, you may want to install something like rbenv to manage your Ruby environment.
• Git
• Bundler
• 4store
  • BioPortal relies on 4store as the main datastore
  • For starting, stopping, and restarting 4store easily, you can try setting up 4s-service
• Redis
  • Used for caching (HTTP, query caching, Annotator cache)
• Solr
  • BioPortal indexes ontology class and property content using Solr (a Lucene-based server)

Configuring Solr

To configure Solr for ontologies_api usage, modify the example project included with Solr by doing the following:

cd $SOLR_HOME
cp example ncbo
cd $SOLR_HOME/ncbo/solr
mv collection1 core1
cd $SOLR_HOME/ncbo/solr/core1/conf
# Copy NCBO-specific configuration files
cp `bundle show ontologies_linked_data`/config/solr/solrconfig.xml ./
cp `bundle show ontologies_linked_data`/config/solr/schema.xml ./
cd $SOLR_HOME/ncbo/solr
cp -R core1 core2
cp `bundle show ontologies_linked_data`/config/solr/solr.xml ./
# Edit $SOLR_HOME/ncbo/solr/solr.xml
# Find the following lines:
# <core name="NCBO1" config="solrconfig.xml" instanceDir="core1" schema="schema.xml" dataDir="data"/>
# <core name="NCBO2" config="solrconfig.xml" instanceDir="core2" schema="schema.xml" dataDir="data"/>
# Replace the value of `dataDir` in each line with: 
# /<your own path to data dir>/core1
# /<your own path to data dir>/core2
# Start solr
java -Dsolr.solr.home=solr -jar start.jar
# Edit the ontologieS_api/config/environments/{env}.rb file to point to your running instance:
# http://localhost:8983/solr/NCBO1

Installing

Clone the repository

$ git clone git@github.com:ncbo/ontologies_api.git
$ cd ontologies_api

Install the dependencies

$ bundle install

Create an environment configuration file

$ cp config/environments/config.rb.sample config/environments/development.rb

config.rb.sample can be copied and renamed to match whatever environment you're running, e.g.:

production.rb
development.rb
test.rb

Run the unit tests (optional)

Requires a configuration file for the test environment:

$ cp config/environments/config.rb.sample config/environments/test.rb

Execute the suite of tests from the command line:

$ bundle exec rake test 

Run the application

$ bundle exec rackup --port 9393 

Once started, the application will be available at localhost:9393.
