coreon-sparql-client is a ui application for making sparql queries to the equivalent Coreon endpoint.
It can be loaded inside an iframe, or run as an independent ui app.
Prerequisites:
- Docker (20.10.8)
- nginx (nginx/1.18.0 (Ubuntu))
In order for the queries to access the endpoint and receive response, two factors are required:
- a repository URI that specifies the target from which the data will be parsed
- an API key for user authentication.
Both pieces of information are meant to be provided dynamically by a parent application (since the current app is configured to be rendered in an iframe inside a parent application).
In order for this app to be run independently, the necessary info will need to be set manually.
To install this application and deploy it as a docker image using nginx, please follow the instructions at https://www.docker.com/blog/how-to-use-the-official-nginx-docker-image/
sudo docker build -t webserver .
sudo docker run -it --rm -d -p 8080:80 --name web webserverThe application can then be accessed at localhost:8080
The UI consists of a form that contains a textarea input. Use this input to build custom queries and submit in order to receive a response from the Coreon sparql endpoint. The response will be rendered as an html table, below the query.
In the case where the client app is hosted within an iframe, the parent application may expose the url to one or multiple HTML files, containing metadata related to the source that is being queried. In the case of Coreon, this source is a repository. In the case of multiple repositories that can be accessed, there must be one HTML file for each corresponding repository. These HTML files must be placed under a directory with the name "samples", which, itself is placed within the "html" directory of the client application.
The client app can fetch and display the repository's name, description and sample queries.
It is required that within the provided HTML file, the relevant strings, be wrapped by elements with corresponding classes, as follows.
- Repository name: "coreon-repo-name"
- Repository description: "coreon-repo-description"
- Repository query: "coreon-sample-query"
There can be multiple sample queries, for each repository.
