The setup repository is part of the Corporate Linked Data Catalog - short: COLID - application. It helps setting up a local environment based on Docker Compose.

Easy setup of the whole environment

The Setup is part of the Corporate Linked Data Catalog - short: COLID - application. Here you can find an introduction to the application. A description of all its functions is here.

The complete guide can be found at the following link.

This repository helps settings up a local environment based on Docker Compose.

Installation instructions

1. Install Docker Desktop for Windows from Docker Hub (latest test with Docker Desktop v2.2.0.3)

2. Clone this repository locally

   git clone --recursive [URL to this Git repo]

3. Pull all changes in all submodules

   git pull --recurse-submodules

4. Create a file .env in parallel to the file docker-compose.yml and insert the following variables (example values are shown):

   MESSAGEQUEUE_COOKIE=SWQOKODSQALRPCLNMEQG
   MESSAGEQUEUE_USERNAME=guest
   MESSAGEQUEUE_PASSWORD=guest
   GRAPHDATABASE_USERNAME=admin
   GRAPHDATABASE_PASSWORD=admin
   RELATIONAL_DATABASE_ROOT_PASSWORD=dbadminpass
   RELATIONAL_DATABASE_USERNAME=dbuser
   RELATIONAL_DATABASE_PASSWORD=dbpass
   SMTP_USERNAME=any
   SMTP_PASSWORD=any
   

5. Run docker-compose up to download and build all Docker images and startup the environment

6. Wait for docker-compose to start up

7. Open the COLID editor (see URL below). Go to the profile menu in the upper right corner and click on "Administration". Open the Metadata Graph Configuration sub-menu page and click the "Start reindex" button in the upper right corner.

8. If you just want to use the Knowledge Graph Explorer Application, then only fuseki, KGE-Frontend and KGE-Web-service docker images needs to be installed.

Known problems

• While building the frontend the following error could occur. In the Dockerfiles of the frontend applications node is used with an increased heap size while building the applications node --max_old_space_size=8000. Try to increase this, if the error occurs.

  FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory
  

• After starting the application a second time, the fuseki database could throw exceptions. Delete the Docker container of the fuseki database with docker container rm fuseki. ATTENTION: This will remove all your created data and reload the database with the initial data.

• fuseki-loader/loader.sh could contain Carriage Return characters, remove them.

Quick Tips

Some quick tips and advices to work faster.

Docker

To purge all unused or dangling images, containers, volumes, and networks run the following command:

docker system prune -a

To remove all containers:

docker container rm $(docker container ls -aq)

Opensearch & Kibana

• After starting the first time, some indices and aliases need to be created
• Open http://localhost:5601, go to the Dev Tools in the left panel, enter and run the following commands

  PUT dmp-resource-1970-01-01_00.00.00
  
  PUT dmp-metadata-1970-01-01_00.00.00
  {
      "mappings": {
          "enabled": false 
      }
  }
  
  POST /_aliases
  {
      "actions" : [
          { "add" : { "index" : "dmp-resource-1970-01-01_00.00.00", "aliases" : ["dmp-search-resource", "dmp-update-resource"] } },
          { "add" : { "index" : "dmp-metadata-1970-01-01_00.00.00", "aliases" : ["dmp-search-metadata", "dmp-update-metadata"] } }
      ]
  }
  

App-wide customization for URL Domain (Optional)

On the Semantic Web, URIs identify not just Web documents, but also real-world objects like people and cars, and even abstract ideas and non-existing things like a mythical unicorn. We call these real-world objects or things. COLID uses the native bayer.com as default domain in each of its URI as the project was conceived for Bayer Ag. For example - https://pid.bayer.com/kos/19050/hasLabel

However you can also configure the custom domain in the URI if needed. In order to do that before building the docker containers, all the triples in the triplestore as well as the references to the URIs should be updated to use the custom domain. Multiple files references across the projects need to be changed from bayer.com to any custom specific domain - https://pid.orange.com/kos/19050/hasLabel Details are mentioned below.

File	Project	Variable	Comments
loader.sh	fuseki-staging	baseUrl	change baseUrl (example.com) as per your need in the shellscript before uploading triples
appsettings.json	AppData Service	ServiceUrl, HttpServiceUrl	change both variables as per your custom domain. "ServiceUrl": "https://pid.example.com/", "HttpServiceUrl": "http://pid.example.com/"
appsettings.json	Indexing Crawler Service	ServiceUrl, HttpServiceUrl	change both variables as per your custom domain. "ServiceUrl": "https://pid.example.com/", "HttpServiceUrl": "http://pid.example.com/"
appsettings.json	Registration Service	ServiceUrl, HttpServiceUrl	change both variables as per your custom domain. "ServiceUrl": "https://pid.example.com/", "HttpServiceUrl": "http://pid.example.com/"
appsettings.json	Reporting Service	ServiceUrl, HttpServiceUrl	change both variables as per your custom domain. "ServiceUrl": "https://pid.example.com/", "HttpServiceUrl": "http://pid.example.com/"
appsettings.json	Search Service	ServiceUrl, HttpServiceUrl	change both variables as per your custom domain. "ServiceUrl": "https://pid.example.com/", "HttpServiceUrl": "http://pid.example.com/"
appsettings.json	Scheduler Service	ServiceUrl, HttpServiceUrl	change both variables as per your custom domain. "ServiceUrl": "https://pid.example.com/", "HttpServiceUrl": "http://pid.example.com/"
appsettings.json	Resource Relationship Manager Backend Service	ServiceUrl, HttpServiceUrl	change both variables as per your custom domain. "ServiceUrl": "https://pid.example.com/", "HttpServiceUrl": "http://pid.example.com/"
environment.ts, environment.docker.ts	Editor Frontend	baseUrl, PidUriTemplate.baseUrl	change baseUrl (example.com) in both sections as per your custom domain
environment.ts, environment.docker.ts	Data Marketplace Frontend	baseUrl	change baseUrl (example.com) as per your custom domain
environment.ts, environment.docker.ts	Resource Relationship Manager Frontend	baseUrl	change baseUrl (example.com) as per your custom domain

COLID: Carrot2 clustering service

Carrot2 clustering service is an opensource for clustering text. It can automatically discover groups of related documents and label them with short key terms or phrases. Please publish few resources in your local COLID Setup and then you can view the clusters in the Data Marketplace. Refer link below for more details
