Relaton::Calconnect is a Ruby gem that implements the IsoBibliographicItem model.

You can use it to retrieve metadata of Calconnect Standards from https://standards.calconnect.org, and access such metadata through the CcBibliographicItem object.

Installation

Add this line to your application’s Gemfile:

gem 'relaton-calconnect'

And then execute:

$ bundle

Or install it yourself as:

$ gem install relaton-calconnect

Usage

Search for a standard using keywords

require 'relaton/calconnect'
=> true

hits = Relaton::Calconnect::Bibliography.search("CC/DIR 10005:2019")
=> <Relaton::Calconnect::HitCollection:0x00000000002df0 @ref=CC/DIR 10005:2019 @fetched=false>

item = hits[0].item
=> #<Relaton::Calconnect::ItemData:0x000000011104c998
...

XML serialization

item.to_xml
=> "<bibitem id="CC-DIR10005-2019" type="standard" schema-version="v1.5.6">
      <title language="en">Guidelines for the implementation of the CalConnect patent policy</title>
      <docidentifier type="CalConnect" primary="true">CC/DIR 10005:2019</docidentifier>
      ...
    </bibitem>"

With argument bibdata: true it outputs XML wrapped by bibdata element and adds flavour ext element.

item.to_xml bibdata: true
=> "<bibdata type="standard" schema-version="v1.5.6">
      <title language="en">Guidelines for the implementation of the CalConnect patent policy</title>
      <docidentifier type="CalConnect" primary="true">CC/DIR 10005:2019</docidentifier>
      ...
      <ext schema-version="v1.1.2">
        <doctype abbreviation="DIR">directive</doctype>
        <flavor>calconnect</flavor>
      </ext>
  </bibdata>

Typed links

Each Calconnect document has link types:

• xml - XML format

• pdf - PDF format

• doc - Microsoft Word document format

• html - HTML format

• rxl - RelatonXML format

item.source

Relaton::Calconnect::Item.from_xml File.read('spec/fixtures/cc_dir_10005_2019.xml')
 => #<Relaton::Calconnect::ItemData:0x000000010ec81040
...

Create bibliographic item from YAML

Relaton::Calconnect::Item.from_yaml File.read('spec/fixtures/item.yaml')

Fetch data

This gem uses the https://raw.githubusercontent.com/usnistgov/NIST-Tech-Pubs/nist-pages/xml/allrecords.xml dataset as one of the data sources.

The method RelatonCalconnect::DataFetcher.fetch(output: "data", format: "yaml") fetches all the documents from the dataset and saves them to the ./data folder in YAML format. Arguments:

• output - folder to save documents (default './data').

• format - the format in which the documents are saved. Possible formats are: yaml, xml, bibxml (default yaml).

Logging

RelatonCalconnect uses the relaton-logger gem for logging. By default, it logs to STDOUT. To change the log levels and add other loggers, read the relaton-logger documentation.

Development

After checking out the repo, run bin/setup to install dependencies. 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 update the index test fixture (used by tests), run rake spec:update_index. This downloads the latest index-v1.zip from the relaton-data-calconnect repository.

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](https://rubygems.org).
