Lerya to set data ‘free’

Dutch geological survey TNO and Norwegian software house Kadme consolidate open source-based data management solution in new unit.

Norwegian data consultancy and software developer Kadme AS and the Dutch geological survey, TNO are setting up a joint venture, Lerya, to ‘liberate’ E&P data from proprietary formats. Kadme and TNO have been collaborating on open source technology for use in National Data Repositories since 2002.


Last year (OITJ Vol. 10 N° 1) the companies announce a standards-based IM solution for the upstream, an international version of TNO’s DINO geo data repository as used to house Dutch geological and environmental data. Lerya’s software embeds Kadme’s K-map and K-doc web services components that leverage open source tools such as the OpenGIS-based MapServer from the University of Minnesota, web services for remote portlets, JBoss and the mySQL database.


Lerya is bidding for the renewal of the prestigious Norwegian DISKOS data management contract, currently run by Schlumberger’s SINAS unit using technology from Landmark, Petris and Kadme itself. Contract award is expected mid April. The word ‘lerya’ is taken from ‘Elvish’, one of several languages invented by Lord of the Rings author J.R. Tolkien. Lerya means ‘to set free, to liberate’.
