  • Show Yahoo semantic search: “dries drupal” <br />
  • <br />
  • Resource Description Framework in attributes <br /> RDFa uses attributes from XHTML's meta and link elements, <br /> and generalises them so that they are usable on all elements. <br /> <br /> Example: <br /> 2006-10-01 <br /> <br /> <br /> <br /> Simple Dublin Core <br /> <br /> The Simple Dublin Core Metadata Element Set (DCMES) consists of 15 metadata elements: <br /> <br /> 1. Title <br /> 2. Creator <br /> 3. Subject <br /> 4. Description <br /> 5. Publisher <br /> 6. Contributor <br /> 7. Date <br /> 8. Type <br /> 9. Format <br /> 10. Identifier <br /> 11. Source <br /> 12. Language <br /> 13. Relation <br /> 14. Coverage <br /> 15. Rights <br /> <br />
  • <br />
  • <br />
  • Simple Protocol and RDF Query Language <br />
  • Important to note here is the \"property orientation\" (class matches can be conducted solely through class-attributes / properties - see Duck typing) <br /> <br /> To make queries concise, SPARQL allows the definition of prefixes and base URIs in a fashion similar to Turtle. In this query, the prefix \"abc\" stands for “http://example.com/exampleOntology#”. <br /> <br />

  • There are content tools for almost everything <br /> We will look at Drupal, Alfresco <br />

  • FP has no side effects <br /> FP - running functions in every order produces same results <br /> FP is useful for parallel processing <br /> Map Reduce is used by Google <br /> Map - Reduce: an algorithm for executing packages in parallel <br /> Map: split into parallel processing packages and produce intermediate output <br /> Reduce: combine intermediate output to produce final output <br />
  • <br />
  • DRY: Don’t repeat yourself <br /> CoC: Convention over Configuration <br /> Reflection: ability to modify code and data <br />
  • <br />
  • Largest in absolute numbers are Java, C++, C# <br /> small but steady growth in C#, C++ steady, some recent growth in Java <br />

  • Why are so many big web sites running LAMP, Python, Ruby on Rails and not Java? <br /> Challenge: large number of evolving and new web interfaces. Large communities are great at implementing these interfaces quickly.Established open source projects typically have large communities. <br /> Enterprise: smaller number of stable interfaces: stability and support important <br />

  • Semantic Web (Web 3.0) Web Application Development Web / Cloud Platforms Web Technology Trends 6
  • Find inter related data more easily Online analysis More automation: allow the computers to do more Semantic Web: Why? 7
  • Question related to Alzheimers: What proteins are involved in signal transduction and are related to pyramidal neurons Search Engine: 223‘000 hits, 0 results Linked healthcare data: 32 hits, 32 results Why Semantic Web: Example 8 Source: Tim Berners-Lee TED Presentation http://www.w3.org/2009/Talks/0204-ted-tbl/
  • Semantic Web 9 Source: http://www.usingmyhead.com/2007/07/31/my-definition-of-the-semantic-web/
  • From a web of documents ... to a web of things “Things” can be: people, places, videos, events ... RDFa: meta data markup for linking “things” uses attributes from XHTML's meta and link elements Representation: Triple: Subject, Predicate, Object Semantic Web - what it is: markup 10

  • Semantic Web: Linked Documents 12 http://www4.wiwiss.fu-berlin.de/bizer/pub/lod-datasets_2009-03-05.html
  • Query the web of related things like a database with: SPARQL: The query language of the semantic Web Semantic Web - what it is: query language 13
  • The following simple SPARQL query returns all country capitals in Africa: PREFIX abc: <http://example.com/exampleOntology#> SELECT ?capital ?country WHERE { ?x abc:cityname ?capital ; abc:isCapitalOf ?y . ?y abc:countryname ?country ; abc:isInContinent abc:Africa . } Variables are indicated by a quot;?quot; or quot;$quot; prefix. Bindings for ?capital and the ? country will be returned. The SPARQL query processor will search for sets of triples that match these four triple patterns, binding the variables in the query to the corresponding parts of each triple. In this query, the prefix quot;abcquot; stands for “http://example.com/ exampleOntology#”. SPARQL Example 14 Source: http://en.wikipedia.org/wiki/Sparql
