Introduction

• The standard technique for personal data interchange is called vCard which appears to be modelled on the old, unsuccessful X.500 directory standard. It's pretty grubby, but since MS Outlook supports it we should too, at least for external interface. The w3c has written a paper that describes how to model vCards in RDF, which should make the data easier to work with. Also, here's some code from HP for working with RDF (and the examples work with RDF vCard's: http://www.hpl.hp.com/semweb/ . It looks interesting - I should play around with it and learn how it works. The query language looks especially cool.
• how should the vCards be stored? One big document with lots of cards (easy to do, might bog down with many cards), or one file per card (what should the files be named?)?
• the standard for scheduling data interchange is called vCalendar, which appears to be also called iCalendar. Some notes from Tim Berners-Lee about representing iCalendar in RDF.
