Sigfrid Lundberg's Stuff
A quotation is much more than an extract
In my last entry, on cool URIs, I discussed the identification of
documents. The conclusion from that is that people in the library world are
obsessed by being able to find documents. I take that more serious than most
other library folk. I'd say that it is our mission to help our patrons find
a single word in a text, a rectangle in an image and so forth. The time is
gone when we could tell users: The answer to your question might be in any
of the books on that shelf.

About this site
I'm a terrible nerd. To use software like content management
systems or blog software is unthinkable for me. There are many ways to build
a site like this. I have chosen one that maximizes the use of angle
brackets.

Att tjäna den demokratiska kulturnationens minne
Jag har arbetat med att programmera digitala bibliotek i ungefär 15
år. När jag läser debatten om biblioteket i Sydsvenskan känner jag att jag
borde säga något. Jag vet inte i vilken utsträckning mitt perspektiv kommer
att kännas relevant för alla de som känner sig kallade att yttra sig, men
jag har en hel del erfarenheter som nog de flesta andra saknar.

Fifteen polar bears and one architecture
Today I gave a presentation on our metadata work. My experience of
that turned out to be about images.
Metadata, 2009
Five years that formed the digital library as we know it:
1997-2001
It appeared to me that many the standards and technologies
underpinning the digital library as we know it were formed during five years
around the turn of the century.

Forgive me, Father, for I have sinned... I have moved a
document
The initiatives behind the persistent linking is trying to change
the status of old documents. From 404 to 200. We've had some success with
books and journals using ISBN and ISSN numbers. Why not try to copy this to
the web? But, alas!, library people have in general too little understanding
of the Worldwide Web. In particular those who advocate persistent
identifiers.

Min mor
Min mor var 43 år gammal när hon födde mig 1956. Alltså föddes hon
själv 1913, året innan första världskriget bröt ut. Nu är hon 96, och lever,
som hon säger, på lånad tid. Tid, det är något som hon tar på största
allvar. Vi talas vid per telefon varje dag. Hon ringer 20.10, nästan
exakt. Det blir alltid ett trevligt samtal.

My first serious experience with ATOM
You don't really understand a document format until you've manually
encoded some documents, and written the software to parse and use it for
something useful. This somewhat refurbished version of my web site is to a
large extent built upon the ATOM syndication format, and here I discuss my
experience.

On Divorce and Unemployment Benefit Societies
Here I analyse of some data retrieved from Google Insight
Search. This little study is inspired by the study performed by Hyunyoung
Choi & Hal Varian, Google Research, were they were able to show that it
is possible to make short-term forcasts of economic behavours using search
statistics.

On being an international commuter
The last four years I've spent more than two hours a day on
trains. And usually, but not always less than three. Furthermore, I go from
one nation to another and participate in the in the digital dissemination of
cultural heritage of a country which isn't my own.

OpenSearch, RSS and OPML as XML Webservices for information
retrieval
At the Royal Library we have been working with the building of an
infrastructure for publishing of digitized material. It is collections of
digital images, usually with very little textual content to go with it. It
is quite a challenge to build workflows satisfying the needs of technical
staff running the scanners, the librararian and editorial staff doing the
cataloging and the needs for crosswalking metadata from the OPAC and at the
same time be able to syndicate the material in other services adhering to
different standards.

Syndication and Simple REST XML web services in a library context
Some time ago I demonstrated our navigation services. In that entry
I promised to tell you more about these services when they are are more
mature. Here is the story on the architecture of some of our new
digitization services.

Metadata processing, 2009
The description and encoding of structure
Much metadata is fairly stright forward. A book does have a title
and an author. That's usually no big deal. We've been able to handle that
for centuries. A digital book has chapters, and everything you might want to
know may be in chapter two on page seventyfive. Or someone may tell you the
solution to your problems after a quarter of an hour in some video on
YouTube. Now, how do we cope with this?

The predator rests on its prey
I've seen this image before. An excavator has demolished a
building, and has then proudly been parked on top of the remnants.

The predigital library
What is the strategic goal for a library web site? Could it be to
put the library on the web, or is it basically to the library's resources
visible to users anywhere on the globe?
Structural web design, 2009
The specification and the TODO-list
Through the web, a software vendor and a service provider could all
of a sudden compete on the same market. The software vendor use the
traditional specification, but a service implies software which is in
continuous development. Strictly speaking, there are no projects anymore,
just different activities. No specifications anymore, but TODO lists
containing incidents, bugs and requests for features ranked by
importance.

Wagging the long tail
The problem with providing an OK Amazoogle experience is that we
might fail in providing advanced services to patrons that have special
needs.

What about the HECS platforms?
I've used fortran, pascal, C, perl, php and java in addition to
more specialized tools such as SQL and XSLT. There is currently a lot of
discussions on what platform will be the next winner.

What does Free mean for The Library
Blogging is out, and the new trend is to tweet in
Twitters. Syndication is out as well, since Google steals your content and
you cannot make money on journalism. How can we survive when all media are
free?

What is a book, and does it matter?
Lorcan Dempsey of OCLC research, is involved in among lots of

make operational definitions of the 'book'.

Why I love XSLT extension functions
xslt extensions allow you to define xpath functions and extension
elements. That makes it easy for you to perform tasks within xslt that are
just only theoretically possible to do.

Why do I keep this site?
Having had a web site for about 15 years, I start to wonder why I
keep it in the first place.

Will the research libraries play a role in e-science
I was asked to participate in an e-science pilot project. The work
in the project has been food for thought for me. Will libraries be a part of
a future eScience infrastructure?
eScience, 2009
XML on the web, Client Side XSLT and Google
The market has forced the major browser manufacturers to converge
on standards. But why are the search engines lagging behind? Browsers are
capable of AJAX and advanced XML processing, but the search engines are
still basically just removing tags and presenting raw text extracts.

NB
My name is Sigfrid Lundberg. The stuff I publish here may, or may not, be of interest for anyone else.
On this site there is material on photography, music, literature and other stuff I enjoy in life. However, most of it is related to my profession as an Internet programmer and software developer within the area of digital libraries at the Royal Library, Copenhagen (Denmark) and, before that, Lund university (Sweden).
The content here does not reflect the views of my past or present employers
