This library parses and generates GML 3.2 application schemas and data sets that conform to:

Installation

To install the gem, add the following line to your Gemfile:

gem 'ogc-gml'

And then execute:

$ bundle install

Usage

To use the OGC GML gem in your Ruby project, require it in your code:

require 'ogc-gml'

Then, you can start using the gem’s functionality.

For example:

# Parse a GML file
gml_data = File.read('spec/fixtures/geospatial_jp_iur_3.1/Bridge_class.xml')
gml = Ogc::Gml::Dictionary.from_xml(gml_data)

# Access the loaded GML Dictionary
gml_dictionary = gml.dictionary
gml_dictionary.features.each do |feature|
  puts feature.name
end

It is possible to utilize the library to develop an Executable Test Suite for GML, similar to the OGC ETS for GML 3.2.
