    Notes on slide 1

    Prodosh Banerjee, Managing Partner, Anolim
    Anolim develops web applications and provides services and solutions for:
    collaboration, marketing / communications, social media, knowledge sharing, e-commerce
    I have been working in IT since 1985 as a manager, consultant, developer
    Director & Head of IT, E-Services UBS Assest Management,
    Consultant Swiss Exchange, IBM Software Labs
    Worked with the Internet since 1996 when I started development of an Internet Banking solution







    Show Yahoo semantic search: “dries drupal”


    Resource Description Framework in attributes
    RDFa uses attributes from XHTML's meta and link elements,
    and generalises them so that they are usable on all elements.

    Example:
    2006-10-01



    Simple Dublin Core

    The Simple Dublin Core Metadata Element Set (DCMES) consists of 15 metadata elements:

    1. Title
    2. Creator
    3. Subject
    4. Description
    5. Publisher
    6. Contributor
    7. Date
    8. Type
    9. Format
    10. Identifier
    11. Source
    12. Language
    13. Relation
    14. Coverage
    15. Rights



    Simple Protocol and RDF Query Language

    Important to note here is the \"property orientation\" (class matches can be conducted solely through class-attributes / properties - see Duck typing)

    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#”.





    There are content tools for almost everything
    We will look at Drupal, Alfresco



    FP has no side effects
    FP - running functions in every order produces same results
    FP is useful for parallel processing
    Map Reduce is used by Google
    Map - Reduce: an algorithm for executing packages in parallel
    Map: split into parallel processing packages and produce intermediate output
    Reduce: combine intermediate output to produce final output


    DRY: Don’t repeat yourself
    CoC: Convention over Configuration
    Reflection: ability to modify code and data


    Largest in absolute numbers are Java, C++, C#
    small but steady growth in C#, C++ steady, some recent growth in Java







    Why are so many big web sites running LAMP, Python, Ruby on Rails and not Java?
    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.
    Enterprise: smaller number of stable interfaces: stability and support important

    Web Technology Trends (early 2009) - Presentation Transcript

    1. Web Technology Trends Prodosh Banerjee, Managing Partner, Anolim http://anolim.com web applications, services & solutions for: collaboration, marketing / communications, social media, knowledge sharing, e-commerce
    2. What Trend? 2 Source: Geek and Poke (http://www.geekandpoke.com) Creative Commons Licensed
    3. Context 3
    4. Context 4
    5. Why Trends? 5
    6. Semantic Web (Web 3.0) Web Application Development Web / Cloud Platforms Web Technology Trends 6
    7. Find inter related data more easily Online analysis More automation: allow the computers to do more Semantic Web: Why? 7
    8. 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/
    9. Semantic Web 9 Source: http://www.usingmyhead.com/2007/07/31/my-definition-of-the-semantic-web/
    10. 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
    11. <?xml version=\"1.0\" encoding=\"UTF-8\"?> <!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML+RDFa 1.0//EN\" \"http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd\"> <html xmlns=\"http://www.w3.org/1999/xhtml\" xmlns:foaf=\"http://xmlns.com/foaf/0.1/\" xmlns:dc=\"http://purl.org/dc/elements/1.1/\" xml:lang=\"en\"> <head> <title>John's Home Page</title> <base href=\"http://example.org/john-d/\" /> <meta property=\"dc:creator\" content=\"Jonathan Doe\" /> </head> <body> <h1>John's Home Page</h1> <p>My name is <span property=\"foaf:nick\">John D</span> and I like <a href=\"http://www.neubauten.org/\" rel=\"foaf:interest\" xml:lang=\"de\">Einstürzende Neubauten</a>. </p> <p> My <span rel=\"foaf:interest\" resource=\"urn:ISBN:0752820907\">favorite book</span> is the inspiring <span about=\"urn:ISBN:0752820907\"><cite property=\"dc:title\">Weaving the Web</cite> by <span property=\"dc:creator\">Tim Berners-Lee</span></span> </p> XHTML and RDFa Example 11 Source: http://en.wikipedia.org/wiki/RDFa#XHTML.2BRDFa_1.0_example
    12. Semantic Web: Linked Documents 12 http://www4.wiwiss.fu-berlin.de/bizer/pub/lod-datasets_2009-03-05.html
    13. 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
    14. 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 \"?\" or \"$\" 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 \"abc\" stands for “http://example.com/ exampleOntology#”. SPARQL Example 14 Source: http://en.wikipedia.org/wiki/Sparql
