2 Agenda SPC: the Italian Interoperability framework The CG-SICA, a SPC s shared infrastructure Overview on services provided by the CG-SICA: SICA s Registers, repositories and directories Qualification of architectural components support eid and access management 2

3 The Italian interoperability framework Italian Digital Administration Code (C.A.D.) Technical Regulations for C.A.D. enforcement Connectivity and Cooperation Public System (SPC) Access to admin. s services Electronic documents exchange Digital signature Software reuse Public data base integration Common specifications for development, security, interoperability and quality of P.A. s services and infrastructural services Nationwide infrastructure Public administration s network made by multi-providers Infrastructural services for interoperability 3

4 Some definitions (from SPC s Technical regulations) SPCoop, the logic subsystem of the SPC consisting of a body of rules and functional specifications that define the application cooperation model for the SPC; SICA, interoperability, cooperation and access infrastructure services, the body of rules, services and shared infrastructures that enables interoperability and application cooperation between the Administrations and access to application services developed and made available on the SPC by those Administrations; telematic service, all functionalities implemented by means of software components, provided through a communication system that can also be accessed via the Internet; application service, all functionalities implemented by means of software components, provided or used by an Administration via the Domain Gateway; 4

5 SPC as a stack of services Backoffice P.A. s services Cooperation Public System Interoperability services Connectivity Public System Network services 5

6 SPC s shared infrastructure Qualified exchange Network (QXN) VoIP (NIV-SPC) Interconnection Node SPC Management Centre (CG-SPC) Interoperability, Cooperation and Access Infrastructure Management Centre (CG-SICA): includes all the general level components (hardware, software, documents, services) for providing the application cooperation services has a support role in relation to the qualification of domain gateways and of any secondary level federated SICA infrastructure services and provides the Committee with elements for assessing the qualitative and quantitative levels of SICA services; 6

11 The SICA Register Service Provides functionalities: to manage the Service Agreements and the Cooperation Agreements. for accessing, registering, updating, cancelling and searching for Service and Cooperation Agreements through integration with the IPA (Public Administrations Directory), for managing information on organisational bodies (public administrations and associated organisational structures, certified electronic mail addresses and Homogeneous Organisational Areas) that operate within the framework of the SPC and of the telematic services provided by them 11

12 Service Agreement The Service agreement shall contain a definition of the service and of the associated procedures for provision and use indicated below: service interface, intended as a set of operations provided by the said service; access points within which the service is available; request procedures and related responses permitted by the service (conversation protocol); semantics of the service and of the information processed; guaranteed service levels; requirements and security characteristics of the service. 12

22 The Schemas/Ontologies Catalogue Service Provides functionalities to describe the semantic elements associated with the application services and with the managed information, including for the purposes of automatically identifying services available for providing the required services, and to share the data and metadata schemas, as well as the domain ontologies, among cooperating Administrations; 22

23 Ontologies Life Cycle Ontology definition using available third party s authoring environment (i.e. Protégé) Ontology pubblication in the Catalog, from OWL and UML v2.0 Query of concepts contained in the Catalog Detailed view and/or deprecation of a selected concept Download of an Ontology associated to a selected concept Deprecation of concepts 23

24 XML Schema (XSD) Life Cycle Schema definition using available editors Schema publication in the Catalog, from XSD file Query of schemas contained in the Catalog Detailed view and/or deprecation of a selected schema 24

25 Relationship between SICA Register and Schemas & Ontologies Catalogue Service Agreements Registry (Registro degli Accordi di Servizio) Contains formal specifications of application services provided to SPCoop network for cooperation, in terms of: SA SA SA Services Agreement repository service description service semantics Catalog of Schemas and Ontologies (Catalogo degli Schemi e delle Ontologie) Contains domain ontologies, data schemas and semantics in order to share and reuse vocabularies (ontologies) and schemas for the service semantics concepts services Off line editor Import & design application Schema & Ontologies catalogue Appl. versioning WEB Query & reasoner Appl.

27 Ontologies and Schemas Management in the Catalog Service Ontologies functionalities Public Administrations can publish ontologies in the Catalog, under own namespace All P.A.s are encouraged to download available ontologies from the Catalog to leverage, extend, and refine them Support for queries and concept-level navigation Supported languages: OWL-DL UML V2.0 class diagrams (only for publishing) Schemas functionalities Public Administrations can publish data schemas in the Catalog All P.A.s are encouraged to download available schemas from the Catalog and reuse them to define new schemas for use in services definition Support for shemas queries Supported languages: XML Schema (XSD) 27

28 Use of Ontologies and Schemas for semantic services Define a service Reuse of available XML Schemas in the Catalog Semantic annotation Join semantics informations to WSDL and XSD using SAWSDL Sharing semantic services Search a service by concepts Publishing Service Agreements with semantic annotation to the SICA Registry Support to semantic searches through Catalog on Service Agreements with Semantic Annotations 28

29 Schemas & Ontologies Catalogue home page 29

30 Example of search on the Catalog Type the keyword to search a concept in the Catalog. The query can be performed on Concept Label, or Description, or See also (one at time) The query result for each concept contains URI, label, a comment, validity (deprecated or not) User can view the details of a selected Concept 30

31 Example of the Details View of a selected concept Concept detail informations: Owner, URI, label Navigation between father/children concepts, Deprecation of the concept List of Ontologies that contain the concept 31
