ontopia-tldr - Tolog Document Retrieval with Ontopia ↑

VERSION ↑

This documentation refers to ontopia-tldr version 0.1.2

DESCRIPTION ↑

Ontopia::TLDR is an attempt at bridging the gap between the worlds of formal knowledge representation (ontologies, topic maps, etc.) and bibliographic document retrieval (bibliographic databases). It allows for retrieving documents from bibliographic databases (currently, only Midos databases are supported) by means of tolog, Ontopia’s topic map query language.

Deployment ↑

Ontopia::TLDR comes as a Sinatra application, so all the standard deployment options apply (rackup, Passenger, etc.). However, in order to allow for maximum flexibility, you need to supply your own config.ru file; e.g. (see Ontopia::TLDR for available options):

require 'ontopia/tldr'

run Ontopia::TLDR.set(
  dbm_file: File.expand_path('../tldr.dbm', __FILE__),
  xtm_file: File.expand_path('../tldr.xtm', __FILE__),

  document_keys: %w[YOUR DOCUMENT KEYS],
  topic_keys:    %w[YOUR TOPIC KEYS],

  title: 'YOUR TITLE'
)

Assuming the following directory layout:

/srv/tldr
  |
  +-- config.ru
  |
  +-- tldr.dbm
  |
  +-- tldr.xtm
  |
  `-- tmp/

Place your database and topic map files there and adjust their paths in the config.ru file. The tmp/ directory is used by Passenger for the restart.txt file.

To deploy Ontopia::TLDR with Passenger on Apache, create a symlink in the DocumentRoot pointing to the app's public/ directory (this example makes use of current_gem; adjust the paths according to your environment):

/var/www
  |
  `-- tldr -> /usr/local/jruby/lib/ruby/gems/shared/current/ontopia-tldr/lib/ontopia/tldr/public

Then put the following snippet in Apache's VirtualHost configuration:

<VirtualHost *:80>
  ...

  RackBaseURI /tldr
  <Directory /var/www/tldr>
    Options -MultiViews
    PassengerAppRoot /srv/tldr                # <-- This (non-standard) line is important
    PassengerRuby /usr/local/jruby/bin/jruby  # <-- And this one sets the Ruby interpreter to JRuby
  </Directory>
</VirtualHost>

SUPPORTED PLATFORMS ↑
