| Abstract | Hera is a designmethodology that supportsthe developmentof web information systems.It is a model-driven methodthat distinguishesfour steps:data retrieval, application modelgeneration, applicationmodelinstancegeneration, and presentationdata generation. Data retrieval populatesthe conceptualmodelwith data. In the application model generation the navigational aspectsof the application are specifiedin the application model. Also, the application model needsto be adaptedfor different user/channelprofiles. In thethird stepof theHera method, theapplicationmodelis populatedwith theretrieveddata. The last step consider s the physical aspectsof the presentation: the retrieveddata wrappedin applicationlogic is translated to different implementationplatforms (e.g. HTML, WML,SMIL).Havingin mindtheadvantageof web application interoperability we choseto implementan experimentalprototypefor the Hera methodusing RDF(S), thefoundationof theSemanticWeb. 1. Intr oduction and relatedwork The Web is the mostpopularsourceof informationtoday. As a result,a key successfactorfor moderninformation systemsis their web presence.From user’s point of view the one-size-fits-allparadigmis not acceptableanymore. The contentneedsto be personalizedfor different usersbasedon their preferences.Moreover suchinformation systemsshould enablemultichannelaccessas more and more userswill reachthem using different platforms (e.g.PC,PDA, WAP phone,WebTV)anddifferentnetwork speeds(e.g.dial-upmodem,network coppercable,network fiber optic cable).Dueto theserequirementsit hasbecome increasinglyimportantto haveanengineered esignof web informationsystems. Research literature provides good references like Relationship Management Methodology (RMM) [9] and Object-OrientedHypermedia Design Methodology (OOHDM) [15] for hypermediadesignmethodologiesthat offer guidelinesto the developer of a Web Information System. However, RMM doesn’ t considerthe multichannel/multiuseraspectsof the presentWeb and OOHDM offersweaksupportfor automation.Recentresearchstudies like WebML [4], XAHM [3], UWE [13], XWMF [11], and Hera[8] give designstepstowardsa (partially) automated generationof hypermediapresentations(from retrieved data)usingmodernweb technologies(e.g.XML, RDF) or object-orientedmodelinglanguages(e.g.UML). All these methodologiesaremodel-based, therole of metadatabeing crucial for automationsupport.Adaptationwith respectto the user’s preferencesor device capabilitiesis considered integrantpartof thedesignprocess. With morethan3 billion pagestheWeb is themostimportantsourceof information.TheemergingSemanticWeb (SW) [1] aims at providing a unique (semantical)view overthisdatathatwill ensurewebapplicationinteroperability. Thefoundationof theSW is theResourceDescription Framework (RDF) [14] andthe RDF Schema(RDFS)[2]. RDFSextendsRDFby providing meansto describedomain vocabularies.XWMF consistsof anextensiblesetof RDF schemataanddescriptionsto modelwebapplications.The choiceto represent modelsin RDF(S)is alsodonein Hera. In contrastto XWMF which is only amodelingframework, Heraprovidesbotha modelingframework andamethodology for developingwebapplications. |
