Ruby Models for the OpenActive Opportunity and Booking Specifications
OpenActive aims to provide model files for all classes defined in its Opportunity and Booking specifications across the PHP, Ruby, and .NET languages. This repository is intended for the Ruby files; see also the PHP and .NET implementations.
Additional documentation can be found at https://www.rubydoc.info/gems/openactive/.
Add this line to your application's Gemfile:
gem 'openactive'And then execute:
$ bundle
Or install it yourself as:
$ gem install openactive
This package provides Ruby models for the OpenActive specifications.
It also provide a set of models for the schema.org specifications.
Finally it provides a set of classes to handle OpenActive's RPDE data feeds.
OpenActive includes OpenActive.io objects as objects for use in Ruby. All classes can be serialized into JSON-LD, to provide easy conformance with the Modelling Specification and Open Booking API Specification.
Please note that type enforcement is in place for both class construction and attribute assignment, providing an invalid type will result in a OpenActive::Exception::InvalidArgumentException being thrown.
Classes for all OpenActive classes are available in the OpenActive::Models and OpenActive::Enums namespaces, and can be easily serialized to JSON-LD, as follows. Enumerations are available as enums for properties that require their use.
event = OpenActive::Models::Event.new(
name: "Virtual BODYPUMP",
event_status: OpenActive::Enums::Schema::EventStatusType::EventScheduled
)
json_ld = event.to_jsonValue of jsonLd:
{
"@context": "https://openactive.io/",
"@type": "Event",
"name": "Virtual BODYPUMP",
"eventStatus": "https://schema.org/EventScheduled"
}The OpenActive data model builds on top of Schema.org, which means that you are free to use additional schema.org properties within OpenActive published data.
To reflect this, OpenActive uses inheritance to build ontop of a copy of Schema.org, these are available within the OpenActive::Models::Schema and OpenActive::Enums::Schema namespaces. And so makes it easy to use additional properties from schema.org on any given type.

}To publish an OpenActive data feed (see this video explainer), The OpenActive gem provides a drop-in solution to render the feed pages. This also includes validation for the underlying feed query.
OpenActive::Rpde::RpdeBody.create_from_modified_id(feedBaseUrl, afterTimestamp, afterId, items)
Creates a new RPDE Page based on the RPDE Items provided using the Modified Timestamp and ID Ordering Strategy, given the afterTimestamp and afterId parameters of the current query. Also validates that the items are in the correct order, throwing a SerializationException if this is not the case.
items = [
OpenActive::Rpde::RpdeItem.new(
Id: "1",
Modified: 3,
State: OpenActive::Rpde::RpdeState::Updated,
Kind: OpenActive::Rpde::RpdeKind::SessionSeries,
Data: @event
),
OpenActive::Rpde::RpdeItem.new(
Id: "2",
Modified: 4,
State: OpenActive::Rpde::RpdeState::Deleted,
Kind: OpenActive::Rpde::RpdeKind::SessionSeries,
Data: nil
)
]
json_ld = OpenActive::Rpde::RpdeBody.new("https://www.example.com/feed", 1, "1", items).to_jsonOpenActive::Rpde::RpdeBody.create_from_next_change_number(feedBaseUrl, afterChangeNumber, items)
Creates a new RPDE Page based on the RPDE Items provided using the Incrementing Unique Change Number Ordering Strategy, given the afterChangeNumber parameter of the current query. Also validates that the items are in the correct order, throwing a SerializationException if this is not the case.
items = [
OpenActive::Rpde::RpdeItem.new(
Id: "1",
Modified: 3,
State: OpenActive::Rpde::RpdeState::Updated,
Kind: OpenActive::Rpde::RpdeKind::SessionSeries,

)
]
json_ld = OpenActive::Rpde::RpdeBody.create_from_next_change_number("https://www.example.com/feed", 2, items).to_jsonReturns the serialized object in hash form complying to json-ld structure (unlike .to_h this serializes everything all the way down.)
event.serialize
{"@type"=>"Event", "name"=>"Virtual BODYPUMP", "eventStatus"=>"https://schema.org/EventScheduled", "@context"=>["https://openactive.io/", "https://openactive.io/ns-beta"]}
Serializes down to a json-ld string.

Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
