ResearchMetadataAnnouncement

Metadata extraction from the Pure Research Information System and transformation of the metadata into an announcement.

Status

Installation

Add this line to your application's Gemfile:

gem 'research_metadata_announcement'

And then execute:

$ bundle

Or install it yourself as:

$ gem install research_metadata_announcement

Usage

Configuration

Create a hash for passing to a transformer.

config = {
  url:      'https://YOUR_HOST/ws/api/59',
  username: 'YOUR_USERNAME',
  password: 'YOUR_PASSWORD',
  api_key:  'YOUR_API_KEY'
}

Transformation

Create a metadata transformer for a Pure dataset.

transformer = ResearchMetadataAnnouncement::Transformer::Dataset.new config

Give it a Pure identifier and get an announcement.

transformer.transform id: 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'

Optionally, use the :composition keyword argument to pass in an array of components (duplicates are ignored). The order of the components determines the order of the metadata in the announcement.

Possible components:

:new, :title, :keywords, :hashtags, :uri

Ideally, an announcement will be obtained using all the requested components, with the following exceptions:

• If the composition includes :keywords or :hashtags and the resource does not have any descriptors, the metadata is simply omitted.

• If the composition includes :uri, the resource must have a URI for an announcement to be returned.

• If, after :title truncation/removal, the length still exceeds the optional :max_length keyword argument, an announcement will not be returned.

If the composition includes :new, a phrase based upon the resource type is generated e.g. New dataset. However, this gem does not determine whether the resource is deemed to be new.

Each example uses a different resource for illustrative purposes.
