+# RSDO (Razvoj Slovenščine v Digitalnem Okolju) - Concordancer
+This repository contains the source code of the concordancer which is a part of the [Terminology Portal](https://github.com/clarinsi/rsdo_term_portal).
+
+There are two main parts:
+- Web application with backend (API interface) written in ASP.NET Core 6 and frontend written in React
+- System Manager which is written in .NET 6 and is used to initially set up the system
+
+## Prerequisites
+Web application requires following external dependencies
+- OpenSearch v2.3.0 (use docker image: `opensearchproject/opensearch:2.3.0`)
+- PostgreSQL (use docker image: `postgres`)
+
+## Building source code
+### Frontend (React application)
+To build a frontend application successfully, first, [Node.js](https://nodejs.org/en/) must be installed (at least version 16).
+Use `npm install` to install all required dependencies, and `npm run build` to build the application.
+For more info see the [Readme](src/apps/Rsdo.Concordancer.Api/WebApp/README.md) inside the frontend [root](src/apps/Rsdo.Concordancer.Api/WebApp) folder.
+
+### Backend (ASP.NET Core 6) and System Manager (.NET 6)
+Open [Rsdo.Concordancer.sln](src/Rsdo.Concordancer.sln) inside of your IDE and build the solution, or use `dotnet build` command to build the solution. All required dependencies will be installed via NuGet packages.
+
+## Creating docker images
+There are two Dockerfile's in the source repository for each part. Both images should be compiled within the context of the project root folder.
+
+### Web application
+[Dockerfile](src/apps/Rsdo.Concordancer.Api/Dockerfile) for Web Application accepts additional optional argument (WEBAPP_PUBLIC_URL) which is mapped to React [PUBLIC_URL](https://create-react-app.dev/docs/using-the-public-folder/) variable. If the variable is omited, then application should be deployed on a domain root.
+
+`docker build -t rsdo-concordancer-api -f src/apps/Rsdo.Concordancer.Api/Dockerfile .`
+
+`docker build --build-arg WEBAPP_PUBLIC_URL=/corpus -t rsdo-concordancer-api -f src/apps/Rsdo.Concordancer.Api/Dockerfile .`
+
+### System Manager
+Use following [Dockerfile](src/apps/Rsdo.Concordancer.SystemManager/Dockerfile) to build System Manager.
+
+`docker build -t rsdo-concordancer-systemmanager -f src/apps/Rsdo.Concordancer.SystemManager/Dockerfile .`
+
+## Environment variables
+
+### Web application
+Web application must be configured with the following Environment variables and values:
+- `RSDO:Database:MasterConnectionString` holds connection string to the main database; e.g.: `rsdo_db;Username=rsdo;Password=strongpassword;Database=Concordancer`
+- `RSDO:Elastic:ConnectionString` holds connection string to OpenSearch server; e.g.: `http://rsdo_opensearch:9200`
+- `RSDO:Tokenizer:ClasslaUrl` holds and url to external service which is used for tokenizing search strings; e.g.: `https://orodja.cjvt.si/oznacevalnik/ajax_api/v1/slv/process`
+
+### System Manager
+System manager must be configured with the following Environment variables and values:
+- `RSDO:Database:MasterConnectionString` holds connection string to the main database; e.g.: `rsdo_db;Username=rsdo;Password=strongpassword;Database=Concordancer`
+- `RSDO:Elastic:ConnectionString` holds connection string to OpenSearch server; e.g.: `http://rsdo_opensearch:9200`
+
+## Using System Manager
+To initialy setup the system, you have to use System Manager and run following commands:
+1. `dotnet Rsdo.Concordancer.SystemManager.dll createMasterDb --connectionString="Host=rsdo_db;Username=rsdo;Password=strongpassword;Database=postgres"` which will create master database with the name Concordancer. You can select different name with the `--name` option
+2. `dotnet Rsdo.Concordancer.SystemManager.dll importSloleks --sourceFile=/data/Sloleks2.0.LMF/sloleks_clarin_2.0.xml` which will import Sloleks (which is used for better searching). XML file is not part of this repository, but it can be downloaded from the following [URL](https://www.clarin.si/repository/xmlui/bitstream/handle/11356/1230/Sloleks2.0.LMF.zip?sequence=3&isAllowed=y)
