RelatonOgc is a Ruby gem that implements the https://github.com/metanorma/metanorma-model-iso#iso-bibliographic-item[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:

[source,ruby]
----
gem 'relaton-ogc'
----

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install relaton-ogc

== Usage

=== Search for a standard using keywords

[source,ruby]
----
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
[source,ruby]
----
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.

----

=== Typed links

Each OGC document has `obp` type link.

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

=== Create bibliographic item from YAML
[source,ruby]
----
hash = YAML.load_file 'spec/fixtures/ogc_bib_item.yml'
=> {"id"=>"19-025r1",
...

RelatonOgc::OgcBibliographicItem.from_hash hash

=== 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`).
