DESCRIPTION

In the last ten years there has been much change in the Dewey ecosystem. One driver has been the European Dewey User Group (EDUG). This presentation, which I held at the EDUG meeting in the National Library of Norway, Oslo in April 2013, tries a look into the crystal ball in order to find out what the Dewey ecosystem looks like in ten years' time. The main points: 1) Dewey has changed some internals, including licensing, versioning and use of facets 2) DDC interoperates well with other knowledges information systems and we have well-established crosswalks in place in order to improve information retrieval 3) The integration of classification data into end-user interfaces is mainstream If this becomes true depends on the people who use the system! If they want it to happen, it will.

The EDUG community has been a large driver behind some of those changes

The DDC is a fully faceted classification (and we use those facets!)

We have verified that the crosswalks actually make retrieval better…

3. The integration of DDC into user interfaces is mainstream

Wow!

For end users we have a seamless inte-gration into catalogues and library portals

Well, it depends on us! And if we believe it can be true, it will.
