  • A collection of essays. Essays have important metadata.
  • Essays are about events, things, people, and places.
  • Essays contain photographs that depict events, things,

people, and places.

  • People participate in any number of relationships. Places

are related to each other geographically. Etc.

  • These relationships are important and interesting (to me,

at least).

cwm [http://www.w3.org/2000/10/swap/doc/cwm.html] I use cwm (“closed world machine” ) to aggregate and apply inference rules to my data. jpegrdf [http://nwalsh.com/java/jpegrdf] I use jpegrdf to store metadata about photographs inside the photographs. Jena [http://jena.sourceforge.net/] Jena is a Java library for accessing RDF graphis. XSLT/RDFTwig [http://rdftwig.sf.net/] I use RDFTwig, a set of extension XSLT extension functions, to make it easier to style RDF data for presentation.
