You may be thinking.\nFor starters, I can quite easily Mesh data from Googlebase (which emits RSS 2.0 or Atom) and other data sources with the Mapping Services from Yahoo!\n\nI can achieve this in minutes without writing a single line of code. I can do it because of the Data Model prowess of RDF (self-describing instance-data), the data interchange and transformation power of XML and XSLT respectively, the inherent power of XML based Web Services (REST or SOAP), and of course, having a Hybrid Server product like Virtuoso at my disposal that delivers a cross platform solution for exploiting all of these standards coherently.\n\nI can share the self-describing describing data source that serves my Meshup. Try reusing the data presented by a Mashup via the same URL that you used to locate Mashup to get my drift.\n\nDemo Links:\n\n\n\n Googlebase Query URL as an RDF Data Source\n\nPerform a simple Data Mesh by adding (via link copy and paste) this Upcoming.org Query Services URL for Ajax Events to the RDF Browsers list of Data Sources (paste into the Data Source URI input field).\n\nWhat does this all mean?\n"Context" is the catalyst of the burgeoning Data Web (Semantic Web Layer - 1). It's the emerging appreciation of "Context" that is driving the growing desire to increment Web versions from 2.0 to 3.0. It also the the very same "Context" that has been a preoccupation of Semantic Web vision since its inception.\nThe journey towards a more Semantic Web is all inclusive (all "ANDs" and no "ORs" re. participation).\nThe Semantic Web is self-annotating. Web 2.0 has provided a huge contribution to the self annotation effort: on the Web we now have Data Spaces for Bookmarks (e.g del.icio.us), Image Galleries ( e.g Flickr), Discussion Forums (remember those comments associated with blog posts? ditto the pingbacks and trackbacks?), People Profiles (FOAF, XFN, del.icio.us, and those crumbling walled-gardens around many Social Networks), and more..\nA Web without granular access to Data is simply not a Web worth having (think about the menace of click-fraud and spam).\n\n" ; atom:title "Data Web, Googlebase, and Yahoo!" . @prefix ns10: . sioc:has_creator ns10:this ; sioc:has_container . @prefix ns11: . sioc:links_to ns11:Virtuoso_Universal_Server , . @prefix ns12: . sioc:links_to ns12:Activity , , , ; atom:source ; atom:author ns1:this ; atom:published "2007-03-22T23:04:21Z" ; atom:updated "2007-03-22T23:14:55Z" . @prefix opl: . opl:isDescribedUsing . ns10:this rdf:type sioc:User . @prefix rdf: . @prefix ns1: . @prefix foaf: . ns1:this rdf:type foaf:Person ; foaf:made . @prefix atom: . rdf:type atom:Feed . @prefix sioct: . rdf:type sioct:Weblog . @prefix rdfs: . rdfs:label "kidehen@openlinksw.com's BLOG [127] description" . @prefix sioc: . sioc:container_of ; atom:entry ; atom:contains . @prefix ns7: . ns7:this rdf:type sioc:User ; sioc:creator_of .
