  • The generated AppLSAC will ba an editor for a data format of your choice.
  • The data will be stored in a JSON and the data format will be defined in a JSON schema.

Defining an appropriate data structure for your purpose and domain is a learning task on its. In this learing resource we will focus on a workflow from a given JSON towards the generatd JSON Editor as AppLSAC.

Learning TaskEdit

Create a JSON Editor as AppLSACEdit

The JSON Editor uses the upload feature of browsers for a server upload to load a local JSON file into the browser without submitting the file to servers on the internet (see AppLSAC/Load). The download feature of browsers for files from remote servers is used to save files to your local file system (see AppLSAC/Save). The difference is that the JSON file in not download from the internet. The JSON file was generated in the browser.

  • (JSON to Schema) Use the given JSON in JSON2Schema, modify the given JSON and create the appropriate JSON Schema.
  • (Schema to JSON Editor) Create a JSON Editor with the generated JSON Schema.
  • (Download JSON Editor) Download the JSON Editor and use the WebApp. as AppLSAC-2 offline or provide the AppLSAC on your web server, so that others can use your WebApp as AppLSAC-1.

JSON2Schema is an AppLSACEdit

JSON2Schema is itself an AppLSAC[3]. If you start JSON2Schema directly from GitLab your run it as AppLSAC-1. It you download JSON2Schema from GitLab your can run it as AppLSAC-2 i.e. you can perform the JSON Editor generation also offline in your browser.
