dwca-codegen 1.0.8

dwca-codegen Documentation

dwca-codegen is a dotnet command line tool that Darwin Core Archive meta-data to generate class files for mapping biodiversity datasets to strongly typed classes.

Installation

Local Install

💡 NOTE: Note: To install a tool locally you must first create a tool manifest as described here

To install the dwca-codegen tool locally open a command prompt in your project folder and enter

dotnet tool install dwca-codegen

Global Install

To install dwca-codegen globally open a command prompt and enter

dotnet tool install -g dwca-codegen

Configuration

The dwca-codegen tool accepts command line parameters and/or options from a dotnet-config configuration file. For information on dotnet-config and the command line tool for manipulating dotnet-config configuration files see https://dotnetconfig.org/.

Initial Configuration File

To create a new default configuration file use the following command.

dwca-codegen config init

This will create a file named .dwca-codegen in one of the following locations depending on whether the tool was installed locally or globally.

The layout of the file will appear similar to the following

# Sample default dwca-codegen configuration file

[dwca-codegen]
	pascalCase
	termAttribute = none
	namespace = DwC
	output = .
[dwca-codegen "usings"]
	using = System
[properties "http://rs.tdwg.org/dwc/terms/coordinatePrecision"]
	typeName = double?
	include
[properties "http://rs.tdwg.org/dwc/terms/coordinateUncertaintyInMeters"]
	typeName = double?
	include
[properties "http://rs.tdwg.org/dwc/terms/dateIdentified"]
	typeName = DateTime?
	include
[properties "http://rs.tdwg.org/dwc/terms/day"]
	typeName = int?
	include
[properties "http://rs.tdwg.org/dwc/terms/decimalLatitude"]
	typeName = double?
	include
    propertyName = Latitude
[properties "http://rs.tdwg.org/dwc/terms/decimalLongitude"]
	typeName = double?
	include
    propertyName = Longitude

The following explains some of the options and what they do

Configuration Listing

To list the current configuration use the following command.

dwca-codegen config list

Usage

To generate classes for an existing archive use the generate command as follows.

dwca-codegen -o code <path to archive file or folder>

This will generate source files for each file in the archive and write them to a subdirectory named code. The output will list the current configuration, including any options that have been overriden on the command line, and list the files that have been created as so.

Created code\Occurrence.cs
Created code\Multimedia.cs

The above example would create class files for Occurrence and Multimedia. The Multimedia file would be a simple POCO file as fillows.

namespace DwC
{
    public partial class Multimedia
    {
        public string Id { get; set; }
        public string Identifier { get; set; }
        public string Type { get; set; }
        public string Type1 { get; set; }
        public string Title { get; set; }
        public string Modified { get; set; }
        public string WebStatement { get; set; }
        public string Source { get; set; }
        public string Source1 { get; set; }
        public string Creator { get; set; }
        public string Creator1 { get; set; }
        public string Description { get; set; }
        public string CreateDate { get; set; }
        public string AccessURI { get; set; }
        public string Format { get; set; }
        public string Format1 { get; set; }
        public string FurtherInformationURL { get; set; }
    }
}

If the termAttribute option is set to name then the [Term()] attribute will be added to the properties as follows.

dwca-codegen -o code -t name ./data/dwca-mvzobs_bird-v34.48.zip

namespace DwC
{
    using DwC_A.Attributes;

    public partial class Multimedia
