# Workingtitle "gemma" //"gemma" is just a temporary title and is likely to be changed.// # Quick Start ## Build - To build all components of gemma, simply type `make` on the top level directory of the repro. - To build all components of gemma, with client in demo mode, use `make demo`. - To only (re)build the back end you can use `make gemma`. - To only build the SPA-Client you can use `make client`. - To only build the SPA-Client in demo mode you can use `make clientdemo`. For further details see [docs/DEVELOPMENT](docs/DEVELOPMENT.md), ## Setup Database - You will need a PostgreSQL cluster with PostGIS. - To install the **gemma** schema and roles use the script `./schema/install-db.sh`. - `./schema/install-db.sh --help` shows you available options. Per default the script will create a database named "gemma" and all necessary roles in the postgres default cluster (listening on port 5432). - The script must be run as a user with PostgreSQL super user rights. By convention this is the "postgres" on most systems. ## Setup GeoServer - Install and run GeoServer as described here: http://docs.geoserver.org/stable/en/user/installation/ - Add tables you want to publish as OGC-Service Layers via GeoServer in the database. For example publish the bottleneck areas: ``` INSERT INTO sys_admin.published_services (name, as_wfs) VALUES ('waterway.bottlenecks', true); ``` In case your gemma is already running (see next section), restart it. Published WFS services will be available at `/api/internal/wfs`. Currently, the same layers will also be available as WMS services at `/api/internal/wms`, regardless of the value of `as_wms` in `sys_admin.published_services`. ## Running gemma - Best is to create a configuration file. Copy the example from `example_conf.toml` to get started: ``` cp example_conf.toml gemma.toml ``` - Edit `gemma.toml`, some parameters you probably want to change: * `host` and `port` to make gemma listen on a public interface * `metamorph-db-password` to match the password for your database user * `geoserver-url`, `geoserver-user` and `geoserver-password` to match your instance of GeoServer - `./cmd/gemma/gemma -h` gives you an overview of more available options. - Then start gemma: ``` ./cmd/gemma/gemma ``` ## Proxying OGC services through gemma - Add services you want to publish via gemma (e.g. for same-origin policy compliance reasons) in the database. For example: ``` INSERT INTO sys_admin.external_services (local_name, remote_url, is_wfs) VALUES ('d4d', 'https://service.d4d-portal.info/wamos/wfs', true); ``` In case your gemma is already running (see previous section), restart it. The services will be available at `/api/external/${local_name}`, thus in the example given above: `/api/external/d4d`. # License //gemma// source code itself licenses as Free Software under GNU Affero GPL v>=3. See the particular source files for details, the license itself can be found in the directory `LICENSES`. To build a complete product, a number of other Free Software components are used, which have their own licenses. To get an overview about the components which are partly included in the resulting production ready-product for the `client/` use `yarn licenses`, e.g. like ```sh yarn licenses list | grep '^├─ ' ``` Additionally inspect `3rdpartylibs.sh` for Go components used for the middleware and their licenses. # Credits Exclusive usage rights (we are in Europe, so it is not Common-law's "copyright"): via donau – Österreichische Wasserstraßen-Gesellschaft mbH, Austria Software-Engineering: Intevation GmbH, Germany
