SchemaShaper

SchemaShaper is a commandline tool for schema conversions. It reads a schema in input format and writes it in the specified output format.

SchemaShaper is targeted to schemas used for data transfer (e.g. messaging).

Features

Supported input schemas:

• avro (Apache AVRO)
• edmx (MS Entity Framework/OData)
• overarch (Overarch Class Model)

Supported output schemas:

• avro (Apache AVRO)
• overarch (Overarch Class Model)

The Overarch output can be used to visualize schemas in an UML class diagram.

Limitations

SchemaShaper may use only parts of the input schema relevant to data transfer. It is also in its early stages, so it might or might not support your use case yet.

Build

SchemaShaper is written in Clojure and gets built with leiningen. To build it, you need to have Java 11 or higher and leiningen installed.

In the cloned SchemaShaper repository, run

lein uberjar

to build a JAR file with all dependencies. This JAR file is created in the target folder and is named schemashaper.jar
