Kalamar-Plugin-ExternalResources

Description

Kalamar-Plugin-ExternalResources is a web service that integrates in the plugin framework of Kalamar, to allow linking texts by their text sigle to external data providers, mainly for full text access.

Kalamar-Plugin-ExternalResources is meant to be a basic plugin and should demonstrate and evaluate the plugin capabilities of Kalamar.

This is software in an early development stage. Its behaviour may change without warnings!

Prerequisites

Go 1.19 or later

Build

To build the latest version of Kalamar-Plugin-ExternalResources, do ...

git clone https://github.com/KorAP/Kalamar-Plugin-ExternalResources
cd Kalamar-Plugin-ExternalResources
go test .
go build .

Running

The binary can be started without prerequisites. The templates folder has to be kept in the root directory. A db folder contains the database.

Registration of the plugin in Kalamar is not yet officially supported - but it works by passing the JSON blob generated at /plugin.json to the plugin registration handler.

Indexation

To index further data, the mappings need to be stored in a csv-file, like

"WPD11/A00/00001","Wikipedia","http://de.wikipedia.org/wiki/Alan_Smithee"
"WPD11/A00/00003","Wikipedia","http://de.wikipedia.org/wiki/Actinium"
"WPD11/A00/00005","Wikipedia","http://de.wikipedia.org/wiki/Ang_Lee"

With the first column being the textSigle (aka the document identifier), the second being the provider name and the third being the URL. These files can be gzipped as well. Then run the indexation with:

./Kalamar-Plugin-ExternalResources data.csv

Customization

The following environment variables can be set either as environment variables or via .env file in the calling directory.

• KORAP_SERVER: The server URL of the hosting service.
• KORAP_EXTERNAL_RESOURCES_PORT: The port the service should be listen to.
• KORAP_EXTERNAL_RESOURCES: The exposed URL the service is hosted.
