RelatonOgc

RelatonOgc is a Ruby gem that implements the IsoBibliographicItem model.

You can use it to retrieve metadata of OGC Standards from https://raw.githubusercontent.com/opengeospatial/NamingAuthority/master/incubation/bibliography/bibliography.json, and access such metadata through the OgcBibliographicItem object.

Installation

Add this line to your application’s Gemfile:

gem 'relaton-ogc'

And then execute:

$ bundle

Or install it yourself as:

$ gem install relaton-ogc

Usage

Search for a standard using keywords

require 'relaton_ogc'
=> true

hits = RelatonOgc::OgcBibliography.search("OGC 19-025r1")
=> <RelatonOgc::HitCollection:0x007fcc8e085ba8 @ref=OGC 19-025r1 @fetched=true>

item = hits[0].fetch
=> #<RelatonOgc::OgcBibliographicItem:0x007fcab3cb4758
...

XML serialization

item.to_xml
=> "<bibitem id="19-025r1" type="standard" schema-version="v1.2.1">
      <fetched>2022-12-04</fetched>
      <title type="title-main" format="text/plain" language="en" script="Latn">Development of Spatial Data Infrastructures for Marine Data Management</title>
      <title type="main" format="text/plain" language="en" script="Latn">Development of Spatial Data Infrastructures for Marine Data Management</title>
      <uri type="obp">https://portal.ogc.org/files/?artifact_id=88037</uri>
      <docidentifier type="OGC" primary="true">19-025r1</docidentifier>
      ...
    </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">
      <fetched>2022-12-04</fetched>
      <title type="title-main" format="text/plain" language="en" script="Latn">Development of Spatial Data Infrastructures for Marine Data Management</title>
      <title type="main" format="text/plain" language="en" script="Latn">Development of Spatial Data Infrastructures for Marine Data Management</title>
      <uri type="obp">https://portal.ogc.org/files/?artifact_id=88037</uri>
      <docidentifier type="OGC" primary="true">19-025r1</docidentifier>
      ...
      <ext schema-version="v1.0.1">
        <doctype>engineering-report</doctype>
        <editorialgroup>
          <committee>technical</committee>
        </editorialgroup>
      </ext>

Typed links

Each OGC document has obp type link.

item.link
=> [#<RelatonBib::TypedUri:0x00007fc848994568 @content=#<Addressable::URI:0x8e8 URI:https://portal.ogc.org/files/?artifact_id=88037>, @type="obp">]

hash = YAML.load_file 'spec/fixtures/ogc_bib_item.yml'
=> {"id"=>"19-025r1",
...

RelatonOgc::OgcBibliographicItem.from_hash hash
=> #<RelatonOgc::OgcBibliographicItem:0x007fc322ef8548
...

Fetch data

This gem uses the https://raw.githubusercontent.com/opengeospatial/NamingAuthority/master/incubation/bibliography/bibliography.json dataset as a data source.

The method RelatonOgc::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 (default yaml).

Logging

RelatonOgc 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 tags, and push the .gem file to [rubygems.org](https://rubygems.org).
