Moreover, it offers\na simple mechanism to register additional user-defined Java objects for mapping CityJSON Extensions.\n\n:information_source: citygson is in **maintenance mode** with no significant active development planned. Existing\nbugs will be fixed, but large new features will likely not be added. citygson was mainly developed for citygml4j v2.\nThe latest [citygml4j v3](https://github.com/citygml4j/citygml4j) brings its own serialization module for the\nCityJSON encoding and, thus, is not dependent on citygson anymore.\n\nLicense\n-------\ncitygson is licensed under the [Apache License, Version 2.0](http://www.apache.org/licenses/LICENSE-2.0).\nSee the `LICENSE` file for more details.\n\nLatest release\n--------------\nThe latest stable release of citygson is 1.2.0.\n\nDownload the citygson 1.2.0 release binaries [here](https://github.com/citygml4j/citygson/releases/download/v1.2.0/citygson-1.2.0.zip).\nPrevious releases are available from the [releases section](https://github.com/citygml4j/citygson/releases).\n\nContributing\n------------\n* To file bugs found in the software create a GitHub issue.\n* To contribute code for fixing filed issues create a pull request with the issue id.\n* To propose a new feature create a GitHub issue and open a discussion.\n\nSupported CityJSON versions\n---------------------------\ncitygson only supports CityJSON 1.0. There are no plans to add support for more recent versions of CityJSON.\n\nBuilding\n--------\ncitygson requires Java 11 or higher. The project uses [Gradle](https://gradle.org/) as build system.\nTo build the library from source, run the following command from the root of the repository.\n\n    \u003e gradlew installDist\n\nThis will create a folder `build/install/citygson`. Simply put the `citygson-\u003cversion\u003e.jar` library file and its\nmandatory dependencies from the `lib` folder on your classpath to start developing with citygson. Have fun :-)\n\nMaven artifact\n--------------\ncitygson is also available as [Maven](http://maven.apache.org/) artifact from the\n[Maven Central Repository](https://search.maven.org/search?q=a:citygson).\nTo add citygson  to your project with Maven, add the following code to your `pom.xml`.\nYou may need to adapt the citygson version number.\n\n```xml\n\u003cdependency\u003e\n  \u003cgroupId\u003eorg.citygml4j\u003c/groupId\u003e\n  \u003cartifactId\u003ecitygson\u003c/artifactId\u003e\n  \u003cversion\u003e1.2.0\u003c/version\u003e\n\u003c/dependency\u003e\n```\n\nHere is how you use citygson with your Gradle project:\n\n```gradle\nrepositories {\n  mavenCentral()\n}\n\ndependencies {\n  compile 'org.citygml4j:citygson:1.2.0'\n}\n```\n\nMore information\n----------------\nCityJSON is a data format for encoding a subset of the [OGC CityGML](http://www.opengeospatial.org/standards/citygml)\ndata model using JSON instead of GML. The [CityJSON specification](https://github.com/cityjson/specs) is developed\nand maintained on GitHub by the [3D geoinformation group at TU Delft](https://3d.bk.tudelft.nl/).\n\ncitygson has been developed in the context of the [CityGML](http://www.opengeospatial.org/standards/citygml)\nJava API [citygml4j](https://github.com/citygml4j/citygml4j) and is used as CityJSON parser in this project.\ncitygml4j adds another data abstraction layer and object model that can be populated from both CityJSON data\nand GML-encoded CityGML data. This way, citygml4j users don't have to choose between the encodings but can\nwrite code that supports both of them.","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcitygml4j%2Fcitygson","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcitygml4j%2Fcitygson","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcitygml4j%2Fcitygson/lists"}
