1. Triple bypass

Hi, and thank you for having us. My name is Martin Malmsten and I am head of Software
Development at the Libris department, at the National Library of Sweden and I will be joined
by some of my collegues later on in the presentation.
Libris is the Swedish Union Catalogue in which university, and some public, libraries
traditionally catalogue their printed material. It is a centrally maintained catalogue which
means that we do have national identifiers and we do not spend all of our time doing
deduplication.
We are here to talk about the new catalogue and cataloguing client being built by Libris and
some of the motivations behind building it.

2. Libris LOD est. 2008
Tuesday, June 4, 13
We’ve had a Linked Open Data implementation for quite some time covering the whole of
Libris including the authority file with persons, organizations, etc. This is very nice and all
and you could say that the Libris implementation is like a flower ... but there is just one
problem.

the Linked Data essentially grows on the back of this Zombie named MARC. Marc has been
declared dead quite a few times, at least the last five ELAGS I assume.

Actually though, he is doing quite well, for being undead at least. A huge part of our
infrastructure, and I mean yours too, not just ours, is still MARC based.
A lot of workflows are MARC-based. We still ship them around.

5. Why change?
•Flexibility
•Get rid of old workflows
•Digitization projects
•Control
•Format agnostisism
•SwePub
•National Discovery?
•Storing objects

Libris faces a number of challenges. But also to be a better web citizen ...

Because publishing Linked Data is not enough. A lot of the potential for efficiency and quality
lies in consuming Linked Data. This has a profound change in how we do systems design. If
there is
Ofcourse the real challenge here is NOT really to create a linked data catalogue. The challenge
is to maintain the existing funxtionality (a lot of which is centered around MARC) and
transition it to something new. Also transition into something that will be easier to transition
OUT of.
Because a lot of what we need is already provided “by the web”.

8. The web is
distributed
Tuesday, June 4, 13
The web is distributed, and it is meant to be distributed. One could say that that is the main
thing. Which is also why ...

9. An aggregate is
not a web
...
neither is a cloud

... an aggregate is not a web. And a cloud is not a web either.

10. Keep MARC on the
outside
Tuesday, June 4, 13
So we do need to coexist with MARC, probably for some time to come. But we can keep MARC
on the outside of the system, not let it be an intergral part that influences core design. In
genreal it’s a good idea to keep the undead on the outside and I kinda wished I had drawn a
picture of that
