   5. Submission of Contributions. Unless You explicitly state otherwise,

      any Contribution intentionally submitted for inclusion in the Work

      by You to the Licensor shall be under the terms and conditions of

      this License, without any additional terms or conditions.

      Notwithstanding the above, nothing herein shall supersede or modify

      the terms of any separate license agreement you may have executed

      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade

      names, trademarks, service marks, or product names of the Licensor,

      except as required for reasonable and customary use in describing the

      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or

      agreed to in writing, Licensor provides the Work (and each

      implied, including, without limitation, any warranties or conditions

      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

      PARTICULAR PURPOSE. You are solely responsible for determining the

      appropriateness of using or redistributing the Work and assume any

      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,

      whether in tort (including negligence), contract, or otherwise,

      unless required by applicable law (such as deliberate and grossly

      negligent acts) or agreed to in writing, shall any Contributor be

      liable to You for damages, including any direct, indirect, special,

      incidental, or consequential damages of any character arising as a

      result of this License or out of the use or inability to use the

      Work (including but not limited to damages for loss of goodwill,

      work stoppage, computer failure or malfunction, or any and all

      other commercial damages or losses), even if such Contributor

      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing

      the Work or Derivative Works thereof, You may choose to offer,

      and charge a fee for, acceptance of support, warranty, indemnity,

      or other liability obligations and/or rights consistent with this

      License. However, in accepting such obligations, You may act only

      on Your own behalf and on Your sole responsibility, not on behalf

      of any other Contributor, and only if You agree to indemnify,

      defend, and hold each Contributor harmless for any liability

      incurred by, or claims asserted against, such Contributor by reason

      of your accepting any such warranty or additional liability.

*This repository is part of the outcomes of the Specialist Task Force 620 focusing on the authoring of a World Representation as part of the ETSI ISG Augmented Reality Framework architecture (https://www.etsi.org/deliver/etsi_gs/ARF/001_099/003/01.01.01_60/gs_ARF003v010101p.pdf).*

*The set of the World Representation authoring components includes:*

*•	The C++ and C# source code for servers and clients  generated from OpenAPI available here (https://forge.etsi.org/rep/arf/arf005)*

*•	A Unity plugin and a Unity editor for authoring and accessing a World Representation hosted on a World Storage server.*

*All these components are available under the ETSI Labs group “World Storage API Helpers”: https://labs.etsi.org/rep/arf/world-storage-api-helpers*

*If you wish to contribute to this project or any other projects in the context of the [ETSI ISG Augmented Reality Framework architecture](https://www.etsi.org/committee/1420-arf), please refer to the ["How to get involved in an ISG" section on the ETSI website](https://www.etsi.org/how-to-get-involved-in-an-isg)*

# Description

This is a small project generating the C# client code and DLLs for the ISG ARF World Storage.

The referenced submodule contains the OpenAPI specification of the ISG ARF World Storage. To checkout the newest version of it use the following commands:

    cd ARF005WorldStorageAPI

    cd openapi

    git checkout master

    cd ..

# Preparing the yaml file (merging)

Before generating the code you must put all referenced YAML file together, otherwies you will get an error in NSwag.For this, we uses a custom tool 'openapi-merger'. This tool only includes file-referenced ref shemas, and do not change local ones (as 'swagger-merger' will do!).

    npm install -g openapi-merger 

## Patching the openfile JS command

If you have some white char in your path/filename, openapi-merger will failed because of an error with the %20 (white pace) in the pathname. To avoid this, please add a line to the js script 'yaml.js' located in your npm path e.g. 

    C:\Users\<YOU>\AppData\Roaming\npm\node_modules\openapi-merger\src

In the readYAML function, the first line:

```c#

function readYAML(filePath) {

    filePath = filePath.replace ("%20", " ");  // White-space bug fixe provided by SylR (FraunhoferHHI)

    const str = "" + fs.readFileSync(filePath, "utf8");

    return yaml.load(str);

}

```

## Using it

To start the merging go into the definition folder of the API and execute this:

    cd openapi/API/worldstorage

    npx openapi-merger -i worldstorageopenapi.yaml -o worldstorageopenapi_merged.yaml 

and also here:

    cd openapi/API/worldanalysis

    npx openapi-merger -i worldanalysisopenapi.yaml -o worldanalysisopenapi_merged.yaml 

Don't forget to change the filename in the JSON config file for NSwag to the merged one!!!

# Installing NSwag

    npm install nswag -g

You can check the version with

    nswag version

# Code Generation

To generate the code and the DLLs use the following commands:

To generate the c# code use the following commands:

    nswag run WorldStorageNSwag.json

    nswag run WorldAnalysisNSwag.json

The generated C# modules (one per definition file) are then contained in the folder `client/csharp-nswag`.

# How to proceed then?

Copy the cs file(s) to your CSharp project or Unity asset folder

## Unity

Add the NewtonSoft package:

"com.unity.nuget.newtonsoft-json": "3.2.1",

Change the Unity prefs to use the NET Framework (not only 2.1)

    npm install

    npm run build

Add a file "csc.rsp":

-r:System.ComponentModel.DataAnnotations.dll

The generated library and its depencies are then contained in the folder `generated_client/bin`.
