6The Network CoreMesh of interconnected routersHow is data transferred through net?packet-switching: data sent thru net in discrete chunks

7The network edge:end systems (hosts):run application programse.g., WWW, emailat edge of networkclient/server modelclient host requests, receives service from servere.g., WWW client (browser)/ server; email client/serverpeer-peer model: host interaction symmetrice.g.: teleconferencing, torrent, napster

Open DataAnyone is free to use, reuse, and redistribute

Linked Open Data (LOD)Publishing and interlinking structured dataon the WWWhttp://linkeddata.org/

Linked Open Data Rating- Available on the web (whatever format), but with an open licence Available as machine-readable structured data (e.g. excel instead of image scan of a table)- Non-proprietary format (e.g. CSV instead of excel)- All the above plus, Use open standards from W3C (RDF) to identify things- All the above, plus: Link your data to other peoples data
