1. Create these three files:

   Code Block
   language text title group.ttl
   @prefix vcard: <http://www.w3.org/2006/vcard/ns#> . <> a vcard:Group; vcard:hasMember "testuser".

   
   

   Code Block
   language text title foo.ttl
   @prefix dc: <http://purl.org/dc/elements/1.1/>. <> dc:title "Hello, World!".

   
   

   Code Block
   language text title acl.ttl
   @prefix acl: <http://www.w3.org/ns/auth/acl#>. <#groupRead> a acl:Authorization; acl:accessTo </fcrepo/rest/foo>; acl:agentGroup </fcrepo/rest/group>; acl:mode acl:Read.

   
   

2. Upload these resources into Fedora:

   Code Block
   language textbash
   curl -X PUT http://localhost:8080/fcrepo/rest/group -u fedoraAdmin:secret3 \ -H "Content-Type: text/turtle" --data-binary @group.ttl curl -X PUT http://localhost:8080/fcrepo/rest/foo -u fedoraAdmin:secret3 \ -H "Content-Type: text/turtle" --data-binary @foo.ttl curl -X PUT http://localhost:8080/fcrepo/rest/foo/fcr:acl -u fedoraAdmin:secret3 \ -H "Content-Type: text/turtle" --data-binary @acl.ttl

   
   

3. Test that testuser can read the foo resource, while adminuser cannot: 

   Code Block
   language textbash
   $ curl -i http://localhost:8080/fcrepo/rest/foo -u testuser:password1 $ curl -i http://localhost:8080/fcrepo/rest/foo -u adminuser:password2

   The first request should respond with 200 OK, while the second should be 403 Forbidden.

   To allow adminuser to also read the foo resource, we can add adminuser to the members of the group.

1. Create group.sparql with the following contents:

   Code Block
   language text title group.sparql
   PREFIX vcard: <http://www.w3.org/2006/vcard/ns#> INSERT DATA { <> vcard:hasMember "adminuser" . }

   
   

2. Run this command to update the group and add adminuser to it:

   Code Block
   language text
   $ curl -i -X PATCH http://localhost:8080/fcrepo/rest/group \ -u fedoraAdmin:secret3 \ -H "Content-Type: application/sparql-update" \ --data-binary @group.sparql

   You should receive a 204 No Content response on success.

1. Now you should be able to repeat the command from step 3 and successfully retrieve the foo resource as adminuser: 

   Code Block
   language textbash
   $ curl -i http://localhost:8080/fcrepo/rest/foo -u adminuser:password2

   This time, you should get a 200 OK response.
