2010-03-18: On indexing of XML using XSLT
One of my really deep interests is the indexing of complex XML
content. Please find here the home page of one my software projects,

2010-03-05: A form with a join
A form is a document, or part of one, that can be used for the
entry of data. A join is a construct in query languages such SQL. A join
allows you to lookup data in one part of a database based on a query in an
other part. Joins are very general, and may appear in other contexts. Such
as the XML forms language.

2009-07-21: 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.

2009-07-09: 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.

2002: S:t Laurentius Digital Manuscript Library: An excursion along the
border between resource discovery and resource description
This note has three aims. First it discusses the experiences
gained by the development of a specific service, which, using a collection
of detailed XML descriptions, provides its users access to a collection
of digitized medieval manuscripts. Secondly, it discusses the database
used from the point of view of both retrieval of the intellectual content
(the texts) of these manuscripts and of the retrieval of the manuscripts
as unique entities. Finally, it explores the possibilities for searching
a collection of complex XML documents using a full text retrieval engine
used together with the Z39.50 information retrieval protocol.

2002: Lecture notes: S:t Laurentius Digital Manuscript Library
In this lecture, I discussed the
experiences gained by the development of a specific service, which, using
a collection of detailed XML descriptions, provides its users access to a
collection of digitized medieval manuscripts. Secondly, I discussed the
database used from the point of view of both retrieval of the intellectual
content (the texts) of these manuscripts and of the retrieval of the
manuscripts as unique entities. Finally, I turned to the possibilities for
searching a collection of complex XML documents using a full text
retrieval engine used together with the Z39.50 information retrieval
protocol.

2008: Digital Humanities Infrastructures
This note discusses different initiatives as regards providing
access to resources and tools aimed at researchers within the
humanities. Since the general breakthrough of search services like Google,
annotation and bookmarking services like del.icio.us and the like, the
attitudes towards the application of computing within the humanities has
changed. In addition, the concept of e-science has contributed to make
scholars positive to apply computing to various problems within the
humanities. Following a discussion started around year 2000, we propose
that it is possible to formalize many humanities computing tasks as
pipelines between XML processing steps.

2004: Ediffah – En digital infrastruktur för forskningsbibliotekens
arkiv- och handskriftssamlingar
Projektet syftar till att göra det möjligt att att skapa skapa
allmänt tillgängliga kataloger och arkivbeskrivningar över bibliotekens
handskriftssamlingar och personarkiv. Systemet skall vara enkelt, och
innehålla ett arbetsflöde sådant att posterna som genereras också med
automatik kan återfinnas i Nationella arkivdatabasen NAD, vårt
gemensamma bibliotekssystem LIBRIS, såväl som i lokala
databaser.

2002: XML -- en mjuk start för biblioteksfolk Mitt ständigt ofärdiga
undervisningsmaterial (...och en del annat)
Denna text syftar till att ge en överblick över vissa områden av
det digitala biblioteksområdet vilka är stadda i snabb utveckling. En
utveckling som i hög grad katalyseras av utvecklingen av olika
tillämpningar av eXtensible Markup Language, XML, som i år fyller fem år.
Utöver användningen av XML inom det digitala biblioteksväsendet ges en
överblick över modernt tänkande när det gäller metadata, hur XML kan
tänkas påverka hur vi tar del av, och hanterar elektroniska texter både i
form av digitalt bevarande och publicering av t ex
forskningsrapporter.

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. I have been that at the Royal Danish Library, Copenhagen (Denmark) and, before that, Lund university library (Sweden).
The content here does not reflect the views of my employers. They are now all past employers, since I retired 1 May 2023.
