PALOMA Functions (standalone or integrated in a LCMS) : complete IEEE-LOM editor with profile and language interface selection. LOM Metatagger (LOMPAD) : complete IEEE-LOM editor with profile and language interface selection. : create, modify, move, suppress LOM and their folders. Multiple Repository manager: create, modify, move, suppress LOM and their folders. for defining/managing user, role and group rights on repositories, folders, sub-folders or LOM. Rights manager: for defining/managing user, role and group rights on repositories, folders, sub-folders or LOM. : boolean combinations of any metadata values (including classifications) to search distributed repositories. Search engine: boolean combinations of any metadata values (including classifications) to search distributed repositories. : interoperability between repositories using different protocols (Ex: CORBA, RMI, SOAP, web services). Actually uses remote JAVA object invocation. Communication API: interoperability between repositories using different protocols (Ex: CORBA, RMI, SOAP, web services). Actually uses remote JAVA object invocation. : LOM repository : LOM can be stored in two formats; XML and RDB. Business logic components implementing the server side API. On Source Forge

Some Difficulties Learning Resources: documents, tools, designs, persons, domain ontologies Multiple repositories and sources Federation and Harvesting Methods Multiplicity of Metadata standards, profiles, control vocabularies, implementations Limitations to referencing Ex: IDLD

Towards a More Intelligent Web First wave: STATIC TEXT / DATA EXCHANGE Second wave: DYNAMIC / MULTIMEDIA Third wave: SEMANTICPROGRAMMABLEPERSONALIZABLE Ontology Semantic annotations to resources enable more “intelligent processing”: search, matching, guiding,…

Domain Ontology Referencing

Two-Way Semantic Referencing Any kind of ressource can be an instance in more than one ontology The technical ontology tells TELOS how to execute it A domain ontology tells a search engine what knowledge and competency is possessed by the ressource

Extending Search Services Align a metadata profile with Telos Ontology using a RDFS store like SESAME. Add a translation operation and Reference it in the TELOS technical ontology Aggregate this operation with the search engine Reference the aggregate in the TELOS technical ontology Integrate the enhanced search engine in any scenario where it can be of use
