LBDserver

The LBDserver client API provides high-level functionality to manage resources on the LBDserver ecosystem. This ecosystem relies on the Solid specifications for data federation and decentralised identity. The LBDserver is a prototype of a "federated Common Data Environment" (CDE), and is one of the main deliverables of the PhD project of Jeroen Werbrouck. For more information, please have a look at the papers listed here or at the WIKI.

Installation

You can install this library with npm install lbdserver-client-api.

Content

The library exposes four Classes:

• LbdService: basic LBDserver-oriented interactions with the Pod (e.g. validate and create LBD project repository)
• LbdProject: interactions with LBDserver projects
• LbdDataset: interactions with datasets of LBDserver projects
• LbdConcept: interactions with "abstract concepts", which relate the identifiers from multiple sources
• LbdDistribution: interactions with distributions of datasets of LBDserver projects.

Further documentation on the functionality of each of these classes is available at https://lbd-hackers.github.io/lbdserver-client-api/.

Usage and Testing

In order to run tests (npm run test) which is also the preferred way of further developing the library (write test and make sure that it passes) you need to first have a local solid community server running, and you need to get credentials that you copy-paste to the credentials.js file.

Run local Solid Community server

• npm install -g @solid/community-server
• community-solid-server
• Register a new account
• Now you have a new WebId (e.g. http://localhost:3000/test/profile/card#me): a username for the Web!

Get session token

This is needed for running the tests or using the library server-side.

• npx @inrupt/generate-oidc-token
• Choose My Solid Identity provider is not on the list and type http://localhost:3000/
• Choose No ("Has your app been pre-registered by the administrator of the Pod server you are signing in to?)
• Type name of the app (consolid)
• Open link in browser (eg. http://localhost:3000/idp/auth?client_id=NFJUCr4Yc0ohwMetVisSB&scope=openid%20offline_access%20webid&response_type=code&redirect_uri=http%3A%2F%2Flocalhost%3A3001%2F&code_challenge=nOIZMSXw0u0OL9GJg7hJMVN09gn05xsM_nxlhfkH6rU&state=7eTv9ZA1rPwx2CH1CrTJqIAVafbc95lZOyxpaZ3_1BM&code_challenge_method=S256&prompt=consent) and login
• You shouls now receive credentials like below

{
  "refreshToken" : "BB",
  "clientId"     : "AA",
  "clientSecret" : "XX",
  "oidcIssuer"   : "http://localhost:3000/",
}

Build and deploy

Building the library is handled with the npm run build command. This generates the lib folder and its content. We build ESM and UMD bundles that can be directly included in an HTML document. Furthermore, we build a CommonJS and an ESM version.

Bundles are build using the configuration in rollup.config.js.
