Droits d'accès dans SweetWikiDe $1Table des matières
Utilisateurs, groupes, rôles et actionsInspiration première : la manière dont DekiWiki gère les droits. Dans la partie admin, il y a un control panel qui permet de gérer des "Roles", un rôle étant associé à une action (cf screenshot ci-dessous). Il y a aussi la gestion des utilisateurs et des groupes, un groupe pouvant se composer d'une liste d'utilisateurs et/ou d'autres groupes. Un utilisateur ou un groupe a un role par défaut.
Spécification des droits pour une resourceDans DekiWiki, pour chaque page, on spécifie son accès "public, semi-public ou privé", et pour les deux derniers cas, on donne la liste des utilisateurs et/ou des groupes qui ont le droit de modifier ou de voir et modifier.
Ontologies proposées et exemples d'annotation pour SweetWikiNous proposons d'étendre l'ontologie du wiki et d'utiliser conjointement une ontologie intitulée provisoirement amo_ont (Access Management Ontology). Nous supposons que les home page de SweetWiki contiennent un profil FOAF dédié à SweetWiki (qui pourra être référencé par un profil FOAF "global", un peu à la manière d'Adil qui a des profils FOAF légers/dédiés sur lastfm, etc... et un gros profil FOAF sur un URL de l'inria). Exemple de profil FOAF dans une home page de sweetwiki<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#" xmlns:owl="http://www.w3.org/2002/07/owl#" xmlns:foaf="http://xmlns.com/foaf/0.1/#" xmlns:xfoaf="http://www.foafrealm.org/xfoaf/0.1/#" xmlns:ex="http://example.org/ex#" xmlns:dc="http://purl.org/dc/elements/1.1/#" xmlns:wiki="http://sweetwiki.inria.fr/ontology#" xmlns:sparql="http://www.w3.org/2005/sparql-results#" xml:base ="http://sweetwiki.inria.fr/AMO_ontology.rdfs/" xmlns:amo="http://sweetwiki.inria.fr/AMO_ontology.rdfs#" > <!-- Access Managment Ontology--> <foaf:Person rdf:nodeID="AnnaKolomoiska" > <foaf:name> Anna Kolomoiska </foaf:name> <foaf:mbox rdf:resource="kalamo4ka@ukr.net"/> <foaf:nick> kalamo4ka </foaf:nick> <foaf:interest rdf:resource="http://www.wikipedia.org" rdfs:label="Wikipedia"/> <foaf:interest> Rollers </foaf:interest> <foaf:homepage rdf:resource="/HomePage_AnnaKolomoiska"/> <amo:hasRole> <amo:Role rdf:nodeID="Admin"/> </amo:hasRole> <foaf:knows> <foaf:Person rdf:nodeID="AngelaBeesley"> <foaf:name> Angela Beesley </foaf:name> <xfoaf:friendshipLevel> 0.7 </xfoaf:friendshipLevel> <foaf:homepage rdf:resource="/HomePage_AngelaBeesley"/> </foaf:Person> </foaf:knows> <foaf:knows> <foaf:Person> <foaf:name> Nastya Baranenko </foaf:name> <xfoaf:friendshipLevel> 0.9 </xfoaf:friendshipLevel> </foaf:Person> </foaf:knows> </foaf:Person> </rdf:RDF> Exemple de page annotée pour spécifier un accès restreintIci, la page a un accès privé, accessible et modifiable par Ania et le groupe des admins. <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#" xmlns:owl="http://www.w3.org/2002/07/owl#" xmlns:foaf="http://xmlns.com/foaf/0.1/#" xmlns:xfoaf="http://www.foafrealm.org/xfoaf/0.1/#" xmlns:ex="http://example.org/ex#" xmlns:dc="http://purl.org/dc/elements/1.1/#" xmlns:wiki="http://sweetwiki.inria.fr/ontology#" xmlns:sparql="http://www.w3.org/2005/sparql-results#" xml:base ="http://sweetwiki.inria.fr/AMO_ontology.rdfs/" xmlns:amo="http://sweetwiki.inria.fr/AMO_ontology.rdfs#" > <!-- Access Managment Ontology--> <foaf:Document rdf:nodeID="PageBy_AnnaKolomoiska"> <foaf:name> PageBy_AnnaKolomoiska </foaf:name> <foaf:maker rdf:nodeID="AnnaKolomoiska"/> <amo:hasAccessType rdf:nodeID="Private"/> <amo:givenAgent> <foaf:Person rdf:nodeID="AnnaKolomoiska"/> </amo:givenAgent> <amo:givenAgent> <foaf:Group rdf:nodeID="GroupAdmins"/> </amo:givenAgent> </foaf:Document> </rdf:RDF> Exemple d'annotation définissant le groupe des admins et leurs rôle/actions par défaut<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#" xmlns:owl="http://www.w3.org/2002/07/owl#" xmlns:foaf="http://xmlns.com/foaf/0.1/#" xmlns:xfoaf="http://www.foafrealm.org/xfoaf/0.1/#" xmlns:ex="http://example.org/ex#" xmlns:dc="http://purl.org/dc/elements/1.1/#" xmlns:wiki="http://sweetwiki.inria.fr/ontology#" xmlns:sparql="http://www.w3.org/2005/sparql-results#" xml:base ="http://sweetwiki.inria.fr/AMO_ontology.rdfs/" xmlns:amo="http://sweetwiki.inria.fr/AMO_ontology.rdfs#" > <!-- Access Managment Ontology--> <foaf:Group rdf:nodeID="GroupAdmins"> <foaf:name> Group of Admins </foaf:name> <foaf:member> <foaf:Person rdf:nodeID="AnnaKolomoiska"/> </foaf:member> <amo:hasRole> <amo:Role rdf:nodeID="Admin"/> </amo:hasRole> </foaf:Group> </rdf:RDF>
