Company overview

"Open Standards and Open Minds"

Many years of experience

Aduna, founded in 1997, is an experienced software developer and implementation partner. The company, strongly inspired by the Semantic Web vision of Tim Berners-Lee, has many years of experience. We supported the growth and adoption of the field by initiating and driving the Sesame project, one of the popular RDF triple stores.


+ Semantic Web

"The Semantic Web is a web of data. There is a lot of data we all use every day, and its not part of the web. I can see my bank statements on the web, and my photographs, and I can see my appointments in a calendar. But can I see my photos in a calendar to see what I was doing when I took them? Can I see bank statement lines in a calendar? Why not? Because we don't have a web of data. Because data is controlled by applications, and each application keeps it to itself. The Semantic Web is about two things. It is about common formats for interchange of data, where on the original Web we only had interchange of documents. Also it is about language for recording how the data relates to real world objects. That allows a person, or a machine, to start off in one database, and then move through an unending set of databases which are connected not by wires but by being about the same thing." -- W3C Semantic Web Activity homepage
