This Thursday I’m in Vienna to participate in the Linked Open Data workshop at ESTC 2010 talking about open data on the semantic web (putting the ‘open’ in linked open data!). Update: slides from talk at ESTC.
Then on Friday (3rd Dec) I’m at the TOP-IX Open Data conference in Torino, Italy to speak on Public Sector Information and Open Data (on the 2nd fellow OKFNer Friedrich Lindenberg will be coordinating a CKAN hack day in Turin as part of the run-up to the main event). Update: slides from TOP-IX talk.

Orri Errling, OpenLink Software
- lod-cloud.net – lod cache
- 18 billion triples
- 8 x 8 core, 16GB servers
- 350m geolocations
[ed]: What’s the cost (if you weren’t corporate)? On, e.g. EC2 (using high memory reserved extra large), this is 8 * ~3k = 24k per year.
Reserve 16GB RAM for every billion triples
Column wise compressed storage architecture
- Columns better for analytics
- Rows betters for lots of transactions
- Virtuoso moves to column based architecture
Monetdb – what can we learn from them
NoSQL – in some ways a cultural thing, a rebellion against the authority of SQL
- Get rid of (some parts) of ACID
- Because google were doing it people thought they should too
- Something of a reaction now

Dear Rufus,
I’m researcher in economics in France and specialized in intellectual property rights especially in the field of biotechnology and pharmaceutical industry ( see attached a short CV). With some colleagues (jurists and economists) we are involved in a important research project sponsored by the French Agency of research (so called ANR) aiming at studying open models of innovations (based on shared access to knowledge), as alternatives to the rising phenomenon of exclusiveness (linked to the reinforcement of IP all over the world). Our study is based on several case studies with the aim of describing the diversity of open models and their conditions of sustainability. Theses case studies concern the fields of: Drugs, genes, biodiversity, open publishing, software, but also IP controversy in the history…. So, it seems that we have a lot of “common objectives†and we would be very glad to know more about your research and your activities and why not thinking about collaboration. I’m writing to you now because I’ll be in Cambridge on January, probably around the 17th f for one week. I would be very pleased to meet you if you were in Cambridge during this period. Looking forward to hearing from you Best regards
