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

It currently retrieves metadata of IHO Standards from https://github.com/relaton/relaton-data-iho.

Add this line to your application's Gemfile:

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

=> [<RelatonIho::Hit:0x007fcab6b9aab8 @text="OGC 19-025r1" @fetched="false" @fullIdentifier="" @title="">]

tem = hits[0].fetch
=> #<RelatonIho::IhoBibliographicItem:0x007fcab3cb4758
...
----

=== XML serialization
[source,ruby]
----
item.to_xml
=> "<bibitem id="19-025r1" type="standard">
      <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.opengeospatial.org/files/?artifact_id=88037</uri>
      <docidentifier type="OGC">19-025r1</docidentifier>
