Relaton3gpp

Relaton3gpp is a Ruby gem that implements the IsoBibliographicItem model.

You can use it to retrieve metadata of W3C Standards from https://w3.org, and access such metadata through the W3cBibliographicItem object.

Installation

Add this line to your application’s Gemfile:

gem 'relaton-3gpp'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install relaton-3gpp

Usage

Search for a standard using keywords

require "relaton_3gpp"
=> true

item = Relaton3gpp::Bibliography.get "3GPP TR 00.01U:UMTS/3.0.0"
[relaton-3gpp] (3GPP TR 00.01U:UMTS/3.0.0) Fetching repository ...
[relaton-3gpp] (3GPP TR 00.01U:UMTS/3.0.0) Found: `3GPP TR 00.01U:UMTS/3.0.0`
=> #<Relaton3gpp::BibliographicItem:0x00007f92d94264e0
...

XML serialization

item.to_xml
=> "<bibitem id="3GPPTR00.01U-UMTS/3.0.0" type="standard" schema-version="v1.2.1">
      <fetched>2022-12-02</fetched>
      <title type="main" format="text/plain">Work programme for the standardization of Universal Mobile Telecommunications System (UMTS)</title>
      <uri type="src">http://www.3gpp.org/ftp/Specs/archive/00_series/00.01U/0001U-300.zip</uri>
      <docidentifier type="3GPP" primary="true">3GPP TR 00.01U:UMTS/3.0.0</docidentifier>
      <docnumber>TR 00.01U:UMTS/3.0.0</docnumber>
      ...
    </bibitem>"

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

item.to_xml bibdata: true
=> "<bibdata type="standard" schema-version="v1.2.1">

Some 3GPP documents have src type link.

item.link.first.type
=> "src"

item.link.first.content
==> #<Addressable::URI:0x320 URI:http://www.3gpp.org/ftp/Specs/archive/00_series/00.01U/0001U-300.zip>

Create bibliographic item from XML

Relaton3gpp::XMLParser.from_xml File.read('spec/fixtures/bibdata.xml')
=> #<Relaton3gpp::BibliographicItem:0x00007fcf5f21af30
...

Create bibliographic item from YAML

hash = YAML.load_file 'spec/fixtures/bib.yaml'
=> {"schema-version"=>"v1.2.1",
 "id"=>"3GPPTR00.01U-UMTS/3.0.0",
...

bib_hash = Relaton3gpp::HashConverter.hash_to_bib hash
=> {:"schema-version"=>"v1.2.1",
 :id=>"3GPPTR00.01U-UMTS/3.0.0",
...

Relaton3gpp::BibliographicItem.new(**bib_hash)
=> #<Relaton3gpp::BibliographicItem:0x00007f92d953cbe0
...

Fetch data

There is a 3GPP dataset latest *.zip which can be converted into RelatonXML/BibXML/BibYAML formats.

The method Relaton3GPP::DataFetcher.fetch(output: "data", format: "yaml") converts all the documents from the dataset and save them to the ./data folder in YAML format. Arguments:

  • source - a data source name. Possible values are: status-smg-3GPP and status-smg-3GPP-force. The first one only downloads a dataset if it’s updated. The second one forces this gem to download the latest dataset.

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

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

Logging

Relaton3gpp 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 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 the created tag, and push the .gem file to [rubygems.org](https://rubygems.org).
