WSMO-Lite Submission• W3C Member Submission as of 23 August 2010 – http://www.w3.org/Submission/WSMO-Lite/• Directors Acknowledgment received on 14 September 2010 – "It is a useful addition to SAWSDL for annotations of existing services and the combination of both techniques can certainly be applied to a large number of semantic Web services use cases."
  12. 12. USDL Incubator Activity 13
  13. 13. USDL -> RDF :AbstractService rdf:type rdfs:Class ; rdfs:comment "AbstractService is used to represent classes of services, i.e. groups of services that share a number of characteristics. AbstractService enables the capturing of these characteristics as a set (configuration) of predefined description properties (USDL objects)." ; rdfs:isDefinedBy <http://www.w3.org/TR/usdl/service> ; rdfs:label "Abstract Service" ; rdfs:subClassOf gr:ProductOrServiceModel . :AbstractServiceType rdf:subClassOf skos:Concept ; rdfs:comment "Types of Abstract Service. Schemes for classifying Abstract Service should start from here" ; rdfs:isDefinedBy <http://www.w3.org/TR/usdl/service> ; skos:prefLabel "Abstract Service Type"@en . :ComposableEntity rdf:type rdfs:Class ; rdfs:comment "Composable serves as the super type of all USDL classes that can be included in a composite service or service bundle. Valid classes are Service, ServiceBundle and AbstractService." ; rdfs:isDefinedBy <http://www.w3.org/TR/usdl/service> ; rdfs:label "Composable Entity" . :CompositeService rdf:type rdfs:Class ; rdfs:comment "A CompositeService is a special type of Service that aggregates other services, service bundles or abstract services. Unlike service bundles, which group services for single-point selling, composite services provide new functionality by combining the capabilities of their parts." ; rdfs:isDefinedBy <http://www.w3.org/TR/usdl/service> ; rdfs:subClassOf gr:ProductOrServicesSomeInstancesPlaceholder , :Service . 14

  23. 23. D9.4.3 OpenData/Mobile Prototype (SOA4All Real Estate Finder)
  24. 24. Description• New action with budget that was left: Not in DOW; completely new, no additional costs• Content: – Usage of SOA4All components in a mobile environment: service discovery, composition, execution – Usage of Open Data initiatives including mobile environments with SOA4All technologies; Usage of Data for localized information (e.g. bus stations…) – Provision of a mobile application for assessing real estate investments• Why Real Estate?• All Services from data.gov.uk initiative 27
  25. 25. DescriptionWhat does it mean?•User View: – Application for finding real estate offers with an iPhone App – based on querying localized information•SOA4All View: – Validation of components in real-world mobile use case, – creation of backend components optimized for mobile use•Developer View: – Provision of examples on how to use SOA4All in iPhone apps on the code level. – Components are adopting their view based on service descriptions. – All source code (including the iPhone app) is opened: https://sourceforge.net/projects/soa4re/ 30
  26. 26. User ViewScenario from User Perspectiove 1. User starts app on his iPhone and selects a location 2. User enters criteria, e.g. looking for a house with 5 rooms 3. User refines search with location based criteria, e.g. Looking for a house in a low crime area of london with a bus stop located in the neigborhood 4. User gets combined results and explores them on a map 31
  27. 27. Frontend Demo Demo 32
  28. 28. Usage of SOA4AllWhat is the role of SOA4All in the scenario?•Service Annotation & iServe – For annotating restful and SOAP based services and publishing them in iServe•Service Discovery – For finding location based services automatically – For wrapping service descriptions into XML for better consumption on iPhone side – Dynamic creation of forms on top on the discovery results! (beta, exploitable)•Services and data stores coming from UK Open Data Initiativese.g. Nestoria, Schools, Bus Stations, Train Stations…•Service Execution 37

  31. 31. Status• 2 Prototypes have been finished• Really working (unlike in other projects ;-))• Version 1.0 already accepted by Apple and listed in the official Apple AppStore• Version 2.0 under submission• Works on iPhone (iOS 4.3) and iPad• Listed at data.gov.uk initiative / Website as featured App• Source opened: https://sourceforge.net/projects/soa4re 40
  32. 32. Status• Officially listed at data.gov.uk as example app for open webservices• http://data.gov.uk/apps/soa4all-real-estate-finder 42
  33. 33. OSS Packaging
  34. 34. Open Source Software• SOA4All OSS Packaging Installer – Installs SOA4All Studio tools and platform services. – A separate installer available for fDSB – Available soon on soa4all.eu under Apache and LGPL licenses• Scenarios for local deployment by third parties – Private deployment (e.g. private registry) – Development: contributing features and fixes• Sources available – http://sourceforge.net/projects/soa4all-st-core – http://fdsb.gforge.inria.fr/ – https://github.com/liudong/iserve – https://github.com/mmale/sweet – … 44

  36. 36. SOA4All ranking before US…• Eclectic ranking – Preferences cannot be combined – Three user interfaces – Some unexploited synergies 46
  37. 37. … and after US• Holistic ranking – Preferences can be combined – Single user interface – Ranking approaches are integrated 47
  38. 38. OSS Explanations
  39. 39. OSS Explanation• A holistic view on using the major tools – Illustrated by a comprehensive scenario – Outside the formal Use Cases – In other scenarios, tools can be mixed and matched• Covering SWS lifecycle
  40. 40. OSS Explanation ScenarioA provider with local knowledge… example: bank service for ATM locations…wants it service to be used. semantic annotation, publishingThe service is visible to a client… discovery, ranking…who reuses it in a complex process. composition 50

  88. 88. Before SOA4All – 1.8B users – more than 1 trillion pagesStatic WWW URI, HTML, HTTP
  89. 89. Before SOA4All Supporting machine delegation and interoperability • search • extraction • representation • interpretation • maintenanceStatic WWW Semantic Web URI, HTML, HTTP RDF, RDF(S), OWL
  90. 90. Before SOA4AllDynamic Web Services UDDI, WSDL, SOAP Enable computation over the Web Static WWW Semantic Web URI, HTML, HTTP RDF, RDF(S), OWL
  91. 91. Before SOA4All Automated Web Service UsageDynamic Web Services Semantic Web UDDI, WSDL, SOAP Services Static WWW Semantic Web URI, HTML, HTTP RDF, RDF(S), OWL
  92. 92. After SOA4AllDynamic REST! Web Services Semantic Web UDDI, WSDL, SOAP Services Static WWW Semantic Web URI, HTML, HTTP RDF, RDF(S), OWL
  93. 93. Conclusions• Web of data is here• Rest services dominate the Web• SOA4All technologies uniquely – Align service descriptions with Web of Data – Abstract over service technologies on the Web – Supported by a comprehensive suite of easy-to-use tools 103
