No Maintenance Intended Build Status
A js library for working with acl files. It allows you to parse the turtle representation, update permissions and agents, and finally convert it back to turtle. It does not cover fetching acl files.
If you don't want to manually fetch and update the acl file, you can take a look at solid-acl-utils.
Please refer to this website for documentation: https://otto-aa.github.io/solid-acl-parser/
This example demonstrates how to parse a turtle string into an AclDoc object, then modify the permissions for a specific user and finally parse it back to turtle.
const SolidAclParser = require('SolicAclParser') const webId = 'https://pod.example.org/profile/card#me' const aclUrl = 'https://pod.example.org/private/file.ext.acl' const fileUrl = 'https://pod.example.org/private/file.ext' const turtle = ` @prefix acl: <http://www.w3.org/ns/auth/acl#>. @prefix foaf: <http://xmlns.com/foaf/0.1/>. <#Read-0> a acl:Authorization; acl:agentClass foaf:Agent; # everyone acl:mode acl:Read; # has Read-only access acl:accessTo <https://pod.example.org/private/file.ext>.` const { AclParser, Permissions } = SolidAclParser const { WRITE, CONTROL } = Permissions async function main() { // Parse the turtle to an AclDoc object which we can modify const parser = new AclParser({ aclUrl, fileUrl }) const doc = await parser.turtleToAclDoc(turtle) // Give the webId WRITE and CONTROL permissions doc.addRule([WRITE, CONTROL], webId) // Parse it back to turtle so we can store it in the pod const newTurtle = await parser.aclDocToTurtle(doc) console.log(newTurtle) } main()
Output turtle
